DEPARTMENT OF TRANSPORTATION Federal Railroad Administration 49 CFR Part 236 [Docket No. FRA-2023-0064] RIN 2130-AC95 Positive Train Control Systems AGENCY:
Federal Railroad Administration (FRA), Department of Transportation (DOT).

ACTION:
Notice of proposed rulemaking (NPRM).

SUMMARY:
FRA is proposing to amend certain regulations governing positive train control (PTC) systems. Since December 31, 2020, by law, PTC systems have generally governed rail operations on PTC-mandated main lines, which encompass nearly 59,000 route miles today. Through FRA's oversight and continued engagement with the industry, FRA has found that its existing PTC regulations do not adequately address temporary situations during which PTC technology is not enabled, including after certain initialization failures or in cases where a PTC system needs to be temporarily disabled to facilitate repair, maintenance, infrastructure upgrades, or capital projects. FRA expects PTC systems to be reliable and robust, further reducing the occurrence of initialization failures and outages. This NPRM proposes to establish strict parameters and operating restrictions under which railroads may continue to operate safely in certain necessary scenarios when PTC technology is temporarily not governing rail operations. The purpose of this NPRM is to enable continued, safe operations and improve rail safety by facilitating prompt repairs, upgrades, and restoration of PTC system service.

Section 20157 of title 49 of the United States Code (U.S.C.) mandates each Class I railroad, and each entity providing regularly scheduled intercity or commuter rail passenger transportation, to implement an FRA-certified PTC system on: (1) its main lines over which poison- or toxic-by-inhalation hazardous materials are transported, if the line carries five million or more gross tons of any annual traffic; (2) its main lines over which intercity or commuter rail passenger transportation is regularly provided; and (3) any other tracks the Secretary of Transportation (Secretary) prescribes by 1 By law, PTC systems must be designed to prevent certain accidents or incidents, including train-to-train collisions, over-speed derailments, incursions into established work zones, and movements of trains through switches left in the wrong position. 2

Currently, 37 host railroads 3 —including 7 Class I railroads, 4 24 entities that provide regularly scheduled intercity or commuter rail passenger transportation (hereinafter referred to as “intercity passenger railroads or commuter railroads,” respectively), and 6 Class II or III, short line, or terminal railroads—are directly subject to the statutory mandate. On December 29, 2020, FRA announced that railroads had fully implemented FRA-certified and interoperable PTC systems on all PTC-mandated main lines. 5 49 U.S.C. 20157(a); 49 CFR 236.1005(b)(7).
3 As this proposed rule primarily focuses on host railroads, FRA references the current number of PTC-mandated host railroads (37). A host railroad is “a railroad that has effective operating control over a segment of track,” and a tenant railroad is “a railroad, other than a host railroad, operating on track upon which a PTC system is required.” See 49 CFR 236.1003(b).
4 FRA acknowledges that one Class I railroad (Canadian Pacific Railway) recently acquired a second Class I railroad (Kansas City Southern Railway). However, for purposes of FRA's PTC regulations and related oversight, FRA is currently counting these railroads separately, as they presently submit separate PTC filings and have indicated they will do so unless and until they fully integrate their PTC systems.

Today, PTC technology is governing rail operations on nearly 59,000 route miles. Based on FRA's oversight of PTC technology since FRA last amended its PTC regulations in 2021, FRA identified three aspects of its existing PTC regulations that warrant revision to address ongoing challenges. Overall, the proposed amendments would benefit the railroad industry, the public, and FRA by facilitating repairs, maintenance, upgrades, and capital improvements; expanding certain railroad informational requirements; reducing costs; and enabling the safe, reliable, and resilient movement of people and goods, while preserving rail safety.
This NPRM proposes to establish strict parameters and operating restrictions under which railroads may continue to operate safely in three specific scenarios when PTC technology is temporarily not governing rail operations:
1. When non-revenue passenger equipment needs to operate to a maintenance facility or yard, for the sole purpose of repairing or exchanging PTC technology;
2. When a PTC system needs to be temporarily disabled to facilitate repair, maintenance, an infrastructure upgrade, or a capital project; and
3. When a system-level or widescale problem occurs resulting in multiple trains' PTC systems failing to initialize.
FRA's objective in this rulemaking is to establish clear, uniform processes, rather than addressing issues that arise in a reactive and piecemeal manner
system needs to be temporarily disabled to facilitate repair, maintenance, an infrastructure upgrade, or a capital project; and
3. When a system-level or widescale problem occurs resulting in multiple trains' PTC systems failing to initialize.
FRA's objective in this rulemaking is to establish clear, uniform processes, rather than addressing issues that arise in a reactive and piecemeal manner. FRA expects that establishing predictable, prescriptive processes will both enable continued operations and improve railroad safety by facilitating prompt repairs, upgrades, and restoration of PTC system service and eliminating uncertainty and inconsistent application of FRA's regulations. FRA's proposed parameters and operating restrictions in this NPRM are intended to be sufficiently strict to ensure that railroads and PTC system suppliers and vendors proactively identify and remedy problems before they arise and immediately correct any problems that may surface despite proactive measures.
First, FRA is proposing to establish an exception, under 49 CFR 236.1006(b)(6), to permit, under certain conditions, non-revenue passenger equipment to operate to maintenance facilities or yards, without being governed by PTC technology. This NPRM proposes to extend the exception currently afforded to certain freight movements to movements of non-revenue passenger equipment, including equipment that is owned or controlled by an intercity passenger railroad or commuter railroad.
This proposed exception would enable non-revenue passenger equipment, including a locomotive, locomotive consist, or train without passengers onboard, to operate to a maintenance facility or yard for the sole purpose of repairing or exchanging 6 a PTC system or component
passenger equipment, including equipment that is owned or controlled by an intercity passenger railroad or commuter railroad.
This proposed exception would enable non-revenue passenger equipment, including a locomotive, locomotive consist, or train without passengers onboard, to operate to a maintenance facility or yard for the sole purpose of repairing or exchanging 6 a PTC system or component. Commuter railroads have informed FRA this proposed exception would be beneficial and necessary, as it would enable them, for example, to operate a PTC-equipped locomotive, where the onboard PTC technology is not functioning and requires repair, to a maintenance facility or yard to repair or exchange the PTC system. To ensure rail safety, FRA is proposing to impose six conditions on each movement of non-revenue passenger equipment subject to this exception, including speed and distance restrictions, the requirement to establish an absolute block (meaning no other traffic may be present in the area), and other protections of the route.
6 FRA's existing regulations, including 49 CFR 236.1029(b)(6), refer to repairing or exchanging a PTC system or component. To clarify, FRA notes that “exchange” is intended to refer to the industry's practice of, for example, swapping out a defective component for a functioning component.
Second, FRA proposes to improve the existing process, under 49 CFR 236.1021(m), that railroads currently utilize to request and obtain FRA's approval to disable their PTC systems temporarily when necessary to facilitate repair, maintenance, infrastructure upgrades, and capital projects. This NPRM proposes to add paragraph (m)(4) to existing § 236.1021 to focus on this specific type of request for amendment (RFA) to PTC systems ( i.e., where a temporary PTC system outage is proposed), as it is different from the other types of RFAs that railroads submit under § 236.1021 and requires additional FRA oversight

This NPRM proposes to add paragraph (m)(4) to existing § 236.1021 to focus on this specific type of request for amendment (RFA) to PTC systems ( i.e., where a temporary PTC system outage is proposed), as it is different from the other types of RFAs that railroads submit under § 236.1021 and requires additional FRA oversight.
FRA proposes to require railroads to provide additional, essential information in an RFA that seeks to temporarily disable a PTC system to enable FRA to evaluate more fully the scope, circumstances, and necessity of a proposed temporary outage and properly determine whether granting the request is in the public interest and consistent with railroad safety. For example, this NPRM proposes to impose nine additional content requirements for this specific type of RFA, including certain justifications, safety analyses, mitigations, and other documentation to demonstrate the proposed outage is as narrow in scope, impact, and duration, as possible.
Third, FRA proposes to reintroduce as a permanent provision a version of a temporary provision regarding PTC system initialization failures, which expired on December 31, 2022. 7 The expired regulatory provision previously permitted any train, including an individual train, to keep operating subject to certain restrictions, if the train failed to initialize for any reason prior to the train's departure from its initial terminal. In FRA's 2014 final rule, FRA 8 In 2014, FRA also observed that “[e]xperience over these intervening years will provide more empirical data on PTC system reliability, and may be a basis for FRA to revisit this issue at a later date should circumstances warrant.” 9

FRA's intention in this NPRM, by proposing to reintroduce an updated version of this provision, is to address only system-level outages or failures that result in multiple trains' PTC systems failing to initialize, impacting the trains of the host railroad and often most, if not all, of its tenant railroads. Currently, if a PTC system fails to initialize, trains are generally prohibited from operating, which has resulted in situations where passengers could be stranded, and vital freight shipments halted.
Although PTC technology is generally reliable and robust, it is a complex technology, composed of many subsystems and dependent on external networks, and it continues to experience unplanned outages. For example, railroads' Quarterly Reports of PTC System Performance 10 show that PTC technology failed to initialize on approximately 236 intercity passenger or commuter trains and 894 freight trains in 2023. 11 Additionally, based on voluntary reporting by railroads, FRA is aware of eight (8) system-level outages that occurred in 2023 that caused multiple trains to fail to initialize.

11 The referenced initialization failures exclude any initialization failures where the source or cause was the onboard subsystem, as proposed § 236.1029(g)(3) excludes such initialization failures from receiving the flexibility afforded under proposed § 236.1029(g), as they typically impact one train. FRA is citing to the relevant initialization failures where the source or cause was, for example, the back office, wayside, or communications subsystems because those types of issues would generally impact more than one train and would be within the scope of this proposed provision.
FRA is proposing to impose two tiers of operating restrictions that would become increasingly restrictive as time passes, to ensure both that railroads utilize any operating flexibility only when necessary and that railroads and their vendors and suppliers identify and resolve issues promptly. FRA expects this will help strike the appropriate balance between enabling continued operations subject to speed restrictions, pending resolution of a PTC failure, and restoring PTC systems as quickly as possible. In short, if a PTC system fails to initialize, impacting multiple trains, FRA proposes to permit railroads to continue operating for 24 hours, subject to the operating restrictions, including speed limits, that previously applied to initialization failures and that currently apply to en route failures. 12 After the first 24 hours, FRA proposes to impose a significant speed limit of restricted speed, among other restrictions, both to help ensure rail safety and to propel the industry to act quickly to restore PTC system service
24 hours, subject to the operating restrictions, including speed limits, that previously applied to initialization failures and that currently apply to en route failures. 12 After the first 24 hours, FRA proposes to impose a significant speed limit of restricted speed, among other restrictions, both to help ensure rail safety and to propel the industry to act quickly to restore PTC system service.
12 An en route failure is a situation where a controlling locomotive experiences a “PTC system failure or the PTC system is otherwise cut out while en route ( i.e., after the train has departed its initial terminal).” 49 CFR 236.1029(b) (emphasis added). FRA's current regulations provide that when an en route failure occurs, a train may continue operating in accordance with certain restrictions, including speed limits that are based on the underlying signal or train control system still in effect, outlined under 49 CFR 236.1029(b)(1) through (6).
FRA analyzed the economic impact of this proposed rule over a 10-year period and estimated its benefits and costs, which are shown in the table below. The total estimated 10-year net benefits would be $81.8 million (discounted at 2 percent), and the annualized net benefits would be $9.1 million (discounted at 2 percent). The industry benefits associated with FRA's proposal to amend three provisions— i.e., to introduce a new exception for certain non-revenue passenger equipment movements, improve the RFA process regarding temporary PTC system outages, and permit continued operations following certain initialization failures, subject to operating restrictions—would outweigh the industry costs and government administrative costs associated with FRA's proposal to expand the content requirements for RFAs related to temporary outages

Discount rates of 2%, 3%, and 7% are used in this analysis. 2 Net Benefits = Industry Benefits − (Industry Costs + Government Administrative Costs). FRA notes that the net industry benefits of this proposed rule may help reduce the overall industry costs for implementing and operating PTC systems. II. Background

A. Legal Authority To Prescribe PTC Regulations
Section 104(a) of the Rail Safety Improvement Act of 2008 required the Secretary to prescribe PTC regulations necessary to implement the statutory mandate, including regulations specifying the essential technical functionalities of PTC systems and how FRA certifies PTC systems. 13 The Secretary delegated to the Administrator of the Federal Railroad Administration the authority to carry out the functions and exercise the authority vested in the Secretary by the Rail Safety Improvement Act of 2008. 49 CFR 1.89(b).
13 Public Law 110-432, 122 Stat. 4848 (Oct. 16, 2008), codified as amended at 49 U.S.C. 20157(g).
In accordance with its authority under 49 U.S.C. 20157(g) and 49 CFR 1.89(b), 14 FRA's PTC regulations under 49 CFR part 236, subpart I, prescribe “minimum, performance-based safety standards for PTC systems . . . including requirements to ensure that the development, functionality, architecture, installation, implementation, inspection, testing, operation, maintenance, repair, and modification of those PTC systems will achieve and maintain an acceptable level of safety.” 49 CFR 236.1001(a). FRA subsequently amended its PTC regulations via final rules published in 2010, 2012, 2014, 2016, and 2021. 15

In this proposed rule, FRA proposes to revise three sections, 49 CFR 236.1006, 236.1021, and 236.1029, of FRA's existing PTC regulations pursuant to its specific authority under 49 CFR 1.89 and 49 U.S.C. 20157(g), and its general authority under 49 U.S.C. 20103 to prescribe regulations and issue orders for every area of railroad safety.
B. Public Participation Prior to the Issuance of the NPRM
FRA regularly engages with host railroads, tenant railroads, PTC system vendors and suppliers, industry associations, and labor organizations, as part of FRA's oversight of railroads' operation of PTC systems on the mandated main lines under 49 U.S.C. 20157 and the other lines where railroads are voluntarily implementing PTC technology

In general, the four industry associations and 35 railroads strongly supported the three objectives of this NPRM. The labor organizations FRA met with supported FRA's objective of enabling operations while maintaining rail safety, but they expressed concern that regulatory flexibility might have the unintended consequence of degrading safety or delaying repairs to PTC technology. Accordingly, with all feedback in mind, FRA drafted its proposed requirements and restrictions in 49 CFR 236.1006(b)(6), 236.1021(m)(4), and 236.1029(g) to prioritize rail safety, address limited circumstances for facilitating repairs, maintenance, and infrastructure upgrades, and enable the safe, reliable, and resilient movement of passengers, commuters, and freight.
As the detailed feedback the associations, railroads, and labor organizations provided during the meetings was directed at a specific proposal in this NPRM, FRA discusses the feedback in the appropriate portions of Section III ( Section-by-Section Analysis ) of this NPRM.
The proposals in this NPRM are based on FRA's own review and analysis and, in part, on the feedback provided during the meetings in 2023 and 2024, specified above. FRA seeks comments on all proposals made in this NPRM.
III. Section-by-Section Analysis
Section 236.1006 Equipping Locomotives Operating in PTC Territory
Existing paragraph (b) in § 236.1006 contains a list of exceptions to the general requirement under paragraph (a) that each locomotive, locomotive consist, or train that operates on any PTC-governed track segment “be controlled by a locomotive equipped with an onboard PTC apparatus that is fully operative and functioning in accordance with the applicable PTCSP approved under this subpart.” 49 CFR 236.1006(a), (b)(1) through (5).
FRA proposes to add a new exception, under proposed paragraph (b)(6), to permit non-revenue passenger equipment to operate to maintenance facilities or yards, without being governed by PTC technology, under certain conditions

FRA proposes to add a new exception, under proposed paragraph (b)(6), to permit non-revenue passenger equipment to operate to maintenance facilities or yards, without being governed by PTC technology, under certain conditions. Currently, a similar exception is available only to freight railroads under existing paragraph (b)(5) of this section. The purpose of new proposed paragraph (b)(6) is to extend that type of exception to movements of certain non-revenue passenger equipment, which would include equipment owned or controlled by an intercity passenger railroad or commuter railroad.
The sole purpose of new proposed paragraph (b)(6) is to enable non-revenue passenger equipment, including a locomotive, locomotive consist, or train, to operate to a maintenance facility or yard for the purpose of repairing or exchanging a PTC system. During FRA's APTA and CRC meetings in February 2024, several commuter railroads, including CMTY, MARC, Metro-North, NICD, and NJT, commented that this proposed exception would be beneficial and necessary, as it would enable them, for example, to operate a PTC-equipped locomotive, where the onboard PTC technology is not functioning and requires repair, to a maintenance facility or yard to repair or exchange the PTC system or component. Without this proposed provision, intercity passenger railroads and commuter railroads would need to utilize rescue trains or, in other words, use an operative, PTC-equipped locomotive, locomotive consist, or train to move the non-operative, PTC-equipped equipment to a maintenance facility or yard. This proposed provision will enable a railroad to repair the equipment more efficiently, thus helping improve rail safety
d provision, intercity passenger railroads and commuter railroads would need to utilize rescue trains or, in other words, use an operative, PTC-equipped locomotive, locomotive consist, or train to move the non-operative, PTC-equipped equipment to a maintenance facility or yard. This proposed provision will enable a railroad to repair the equipment more efficiently, thus helping improve rail safety.
During FRA's meetings in February 2024, commuter railroads cited often experiencing issues with transporting equipment requiring repair to their maintenance facilities, including unavailability of equipment and cascading schedule delays, and they supported this proposed exception, even though it would potentially constrain some operations. For example, the introductory text of proposed paragraph (b)(6) makes it clear that this proposed exception would apply only to non-revenue movements, meaning no intercity passenger or commuter rail service could be provided while moving this equipment not governed by a PTC system.
Proposed paragraphs (b)(6)(i) through (v) and (vii) outline the six additional conditions FRA proposes an intercity passenger railroad or commuter railroad must satisfy while utilizing this proposed exception. First, proposed paragraph (b)(6)(i) would limit the speed of the locomotive, locomotive consist, or train to a maximum of 49 miles per hour (mph), which is significantly slower than the normal maximum authorized speed for passenger equipment, which generally ranges between 79 mph and 150 mph.
Second, proposed paragraph (b)(6)(ii) would require an absolute block 18 to be established in front of the locomotive, locomotive consist, or train. This would help ensure safety by essentially eliminating the possibility of a train-to-train collision. During FRA's February 2024 meetings, CMTY, SMART, and UTA FrontRunner commented that they currently use absolute blocks in similar circumstances and supported the proposal of this condition
d require an absolute block 18 to be established in front of the locomotive, locomotive consist, or train. This would help ensure safety by essentially eliminating the possibility of a train-to-train collision. During FRA's February 2024 meetings, CMTY, SMART, and UTA FrontRunner commented that they currently use absolute blocks in similar circumstances and supported the proposal of this condition.
18 Under 49 CFR 236.709, an absolute block is defined as a “block in which no train is permitted to enter while it is occupied by another train.”
Third, proposed paragraph (b)(6)(iii) specifies that there cannot be any working limits established under part 214 of this chapter on any part of the route. FRA proposes to eliminate the risk of an incursion into an established work zone by not permitting work zones or any roadway workers at all on the route the non-revenue passenger equipment uses to reach the maintenance facility or yard to repair or exchange its PTC technology. To be clear, roadway workers may not perform any work on the route where the non-revenue passenger equipment operates subject to this proposed exception, until after the equipment arrives at its destination, the maintenance facility or yard.
Fourth, proposed paragraph (b)(6)(iv) specifies that the locomotive, locomotive consist, or train could operate in non-revenue service no farther than the next forward location designated in the railroad's PTCSP for the repair or exchange 19 of PTC technology. During FRA's meeting with labor organizations in February 2024, BLET and BRS commented that they were concerned a railroad might utilize this proposed exception to avoid repairing the PTC system or to delay repairing the PTC system by operating the equipment to a more distant repair location than available.
19 To clarify, FRA notes that “exchange” is intended to refer to the industry's practice of, for example, swapping out a defective component for a functioning component

19 To clarify, FRA notes that “exchange” is intended to refer to the industry's practice of, for example, swapping out a defective component for a functioning component.
Relatedly, during a meeting in February 2024, NICD observed that the structure of commuter rail operations would inherently prevent railroads from overusing any exception or provision that involves speed restrictions because of the negative impact that has on their operations. For example, even a single train operating at a slower speed can create scheduling issues and cascading delays for commuter trains. In addition, FRA expects that its proposed conditions, including the imposition of a speed restriction, the prohibition against work zones, and an absolute block requirement, would prevent overuse of this exception. Also, FRA crafted proposed paragraph (b)(6)(iv) with BLET and BRS's comments in mind, and this proposed condition would explicitly prohibit the non-revenue passenger equipment from operating farther than the next forward designated location in the railroad's FRA-approved PTCSP.
Fifth, similar to a condition in the existing freight version of this exception in paragraph (b)(5) of this section, proposed (b)(6)(v) would require the railroad to protect the route against conflicting operations and establish and comply with sufficient operating rules to protect against a train-to-train collision and the movement of a train through a switch left in the wrong or improper position. This condition would further reduce the possibility of a train-to-train collision as it would address traffic on intersecting tracks
would require the railroad to protect the route against conflicting operations and establish and comply with sufficient operating rules to protect against a train-to-train collision and the movement of a train through a switch left in the wrong or improper position. This condition would further reduce the possibility of a train-to-train collision as it would address traffic on intersecting tracks. Furthermore, to protect against the movement of a train through a switch left in the wrong or improper position, a railroad's operating rules could, for example, explain that the railroad utilizes a system or technology capable of monitoring switches. If a railroad does not have such a system or technology, a switch's position must be manually verified before any movement over the switch points. To accomplish this, a switch tender must check the switch, or the train crew must stop and then confirm the switch position before operating over the switch.
During an FRA meeting in February 2024, SFRTA inquired whether FRA intends to limit the distance of the movement of non-revenue passenger equipment in this proposed exception, as it does in the freight railroad exception in existing paragraph (b)(5). FRA notes that the purpose of the two exceptions is different: the purpose of the freight exception in paragraph (b)(5) is to facilitate freight switching and freight transfer train service, including in revenue service, in or near yards, whereas the purpose of the proposed paragraph (b)(6) exception would be to enable non-revenue passenger equipment to reach maintenance facilities or yards, without being governed by PTC technology, for the specific purpose of repairing or exchanging a PTC system. The commuter railroad SMART commented that it would not be possible to identify a specific distance that applies to all cases because the distance to each intercity passenger or commuter railroad's maintenance facilities and yards, based on the starting point, is unique
facilities or yards, without being governed by PTC technology, for the specific purpose of repairing or exchanging a PTC system. The commuter railroad SMART commented that it would not be possible to identify a specific distance that applies to all cases because the distance to each intercity passenger or commuter railroad's maintenance facilities and yards, based on the starting point, is unique. FRA agrees, as the applicable distance varies greatly based on case-by-case circumstances. Accordingly, rather than imposing an exact distance limit, FRA expects that the five conditions in proposed paragraphs (b)(6)(i) through (v) would sufficiently define the scope of this exception.
Proposed paragraph (b)(6)(vi) provides that FRA may, in its discretion, approve alternative criteria and conditions, in a PTCSP or an RFA to a PTCSP, if the railroad demonstrates that the alternative criteria and conditions would provide an equivalent or greater level of safety than the default criteria and conditions. FRA is proposing to add this paragraph to mirror that discretionary element of the freight yard movements exception in existing paragraph (b)(5)(vii). Proposed paragraph (b)(6)(vi) provides the opportunity for railroads to propose alternative applications of this exception to FRA for review and approval. An intercity passenger railroad or commuter railroad must obtain FRA's approval only if it seeks to use alternative exception criteria or conditions under proposed paragraph (b)(6)(vi), whereas the standard exception for non-revenue passenger equipment movements would be immediately available for use for any movement that meets all default criteria and conditions in proposed paragraphs (b)(6)(i) through (v). 20

Finally, proposed paragraph (b)(6)(vii) imposes a notification requirement that a railroad must satisfy before moving non-revenue passenger equipment pursuant to this exception. Specifically, this paragraph proposes that before utilizing the default exception under paragraphs (b)(6)(i) through (v) or the discretionary exception under paragraph (b)(6)(vi), the railroad must notify each person involved with the movement of the non-revenue passenger equipment, including any dispatchers and train crews, in addition to any roadway workers who may no longer work on that segment during the movement subject to this exception.
Section 236.1021 Discontinuances, Material Modifications, and Amendments
On December 31, 2022, the regulatory provision under 49 CFR 236.1029(g)(3) expired, which previously permitted a railroad to temporarily disable its PTC system when necessary to perform PTC system repair or maintenance, after notifying an FRA regional office. As § 236.1029(g)(3) has expired, a simple notification to FRA no longer suffices, and a railroad must obtain FRA's approval through an RFA pursuant to 49 CFR 236.1021(m) before a railroad temporarily disables its PTC system and continues rail operations
railroad to temporarily disable its PTC system when necessary to perform PTC system repair or maintenance, after notifying an FRA regional office. As § 236.1029(g)(3) has expired, a simple notification to FRA no longer suffices, and a railroad must obtain FRA's approval through an RFA pursuant to 49 CFR 236.1021(m) before a railroad temporarily disables its PTC system and continues rail operations.
The purpose of existing § 236.1021, in relevant part, is to prohibit a railroad from making certain changes to its PTC system or disabling or discontinuing its PTC system, unless the railroad first submits an RFA to its PTC system with certain information and obtains FRA's approval.
This NPRM proposes to add a new paragraph (m)(4) to § 236.1021 to clarify that the RFA process under existing paragraph (m) applies to a case where a railroad seeks to temporarily disable its PTC system, and to continue operations during that time, to facilitate repair, maintenance, infrastructure upgrades, or capital projects. During FRA's meetings with AAR, APTA, ASLRRA, CRC, and their member railroads in November 2023 and February 2024 to discuss this NPRM, these four associations and several railroads, including all Class I railroads, Alaska Railroad, Amtrak, G&W, Metra, Metro-North, Metrolink, and SFRTA, expressed general support for FRA's proposal to revise existing paragraph (m) to acknowledge explicitly that it covers RFAs to PTC systems involving temporary outages.
Specifically, proposed paragraph (m)(4) clarifies that a host railroad must utilize the RFA process under paragraph (m) to request and obtain FRA's approval of a temporary PTC system outage, during which train movements may continue, including a short-term outage related to repair, maintenance, an infrastructure upgrade, or a capital project
overs RFAs to PTC systems involving temporary outages.
Specifically, proposed paragraph (m)(4) clarifies that a host railroad must utilize the RFA process under paragraph (m) to request and obtain FRA's approval of a temporary PTC system outage, during which train movements may continue, including a short-term outage related to repair, maintenance, an infrastructure upgrade, or a capital project. 21 To provide non-exhaustive examples of what a temporary PTC system outage includes, proposed paragraph (m)(4) clarifies that the term includes, but is not limited to, any scenario when the onboard PTC apparatus or subsystem, wayside subsystem, communications subsystem, or back office subsystem would be disabled. FRA interprets the term “disabled” broadly and acknowledges the industry also uses the verb “disengage” interchangeably in this context.
21 Several railroads have expressed that their chief concern is a path forward for undertaking non-PTC-related capital projects that necessitate temporarily disabling the PTC system, and FRA is using the general term “capital projects” in this NPRM to avoid any ambiguity and clarify that this process applies to such projects.
Consistent with the current process under existing paragraph (m), proposed paragraph (m)(4)(i) provides that a railroad may temporarily disable PTC technology pursuant to this paragraph only after it obtains approval from the Director of FRA's Office of Railroad Systems and Technology.
Based on FRA's experience reviewing RFAs involving temporary outages throughout 2023 and 2024 to date, FRA found that the current content requirements for RFAs to PTC systems under existing paragraph (m)(2) do not yield sufficient information for FRA to assess the full scope and circumstances of each proposed temporary outage
from the Director of FRA's Office of Railroad Systems and Technology.
Based on FRA's experience reviewing RFAs involving temporary outages throughout 2023 and 2024 to date, FRA found that the current content requirements for RFAs to PTC systems under existing paragraph (m)(2) do not yield sufficient information for FRA to assess the full scope and circumstances of each proposed temporary outage. Accordingly, proposed paragraphs (m)(4)(ii)(A) through (I) identify nine additional content elements this type of RFA must include, in addition to the standard content requirements under paragraph (m)(2), which apply to a broader cross-section of RFAs to PTC systems and PTCSPs.
Proposed paragraph (m)(4)(ii)(A) would require this specific type of RFA to describe the necessity for the proposed temporary outage. For example, in 2023 and 2024, railroads have filed RFAs seeking to temporarily disable a PTC system to facilitate the installation of automatic train control or a new interlocking, or to execute an upgrade of a computer-aided dispatch system, a back office server migration or replacement, or an electrical infrastructure upgrade. This section of the RFA would explain why temporarily
Proposed paragraph (m)(4)(ii)(B) would require the RFA to describe the physical limits and PTC system functions that would be affected by the proposed temporary outage. This section of the RFA would require an analysis that demonstrates the affected physical limits and affected functions pose the least risk to railroad safety, compared to other options. To assess the RFA, FRA needs to understand the exact location(s) that will be impacted, including milepost limits and other descriptors. Identifying the precise PTC system functions that would be impacted is also essential for FRA to understand the scope of the temporary outage, as an outage might impact only a narrow set of PTC system capabilities

Identifying the precise PTC system functions that would be impacted is also essential for FRA to understand the scope of the temporary outage, as an outage might impact only a narrow set of PTC system capabilities.
Proposed paragraph (m)(4)(ii)(C) would require the RFA to include an explanation about how the proposed temporary outage is in the public interest and consistent with railroad safety. Existing § 236.1021(f) requires FRA to determine whether granting a request is in the public interest and consistent with railroad safety, and it is important for an RFA to provide such information.
Proposed paragraph (m)(4)(ii)(D) would require the railroad to provide the proposed timeframe of the temporary outage and an analysis that demonstrates the proposed period poses the least risk to railroad safety, compared to other times. This proposal mirrors a similar requirement under former § 236.1029(g)(3)(ii), which expired in December 2022. FRA has seen railroads prudently identify the timeslot of a specific day of the week with the least traffic, which is what FRA expects this content requirement will help ensure in future RFAs.
As a note, FRA has also seen cases where a railroad avoids needing to submit and obtain FRA's approval of an RFA involving a temporary outage, as the railroad either ceases all operations until it finishes the relevant work, or the railroad selects a time when no trains will operate. FRA commends railroads for structuring their projects that way and expects railroads to submit an RFA, seeking to disable its PTC system temporarily with continued rail service, under proposed paragraph (m)(4) only when ceasing operations would not be feasible

FRA commends railroads for structuring their projects that way and expects railroads to submit an RFA, seeking to disable its PTC system temporarily with continued rail service, under proposed paragraph (m)(4) only when ceasing operations would not be feasible.
Relatedly, proposed paragraph (m)(4)(ii)(E) would require the RFA to include both a justification and an analysis that show how the proposed duration of the temporary outage is the minimum time necessary to complete the pertinent work, test the PTC system, and place the PTC system back into service without undue delay. FRA highlights that proposed paragraph (m)(4) is intended to address short-term outages only, and FRA will deny an RFA that seeks to disable a PTC system for an unreasonable, extensive period. In general, PTC-mandated main lines must be governed by PTC technology, given the presence of intercity passenger rail, commuter rail, or certain freight transportation. See, e.g., 49 U.S.C. 20157(a); 49 CFR 236.1005(b), 236.1006(a). Railroads must show how the length of the proposed temporary outage is the minimum amount of time needed based on the circumstances, which could include outlining a precise schedule and the number of hours involved in each phase and justifications for each timeframe.
Proposed paragraph (m)(4)(ii)(F) would require the RFA to outline the type and frequency of rail operations that would continue during the proposed temporary outage, including those of the host railroad and each tenant railroad.
Proposed paragraph (m)(4)(ii)(G) would require the RFA to identify the applicable speed limit of any train that would operate during the proposed temporary outage, and any other operating restrictions in place to ensure rail safety
ine the type and frequency of rail operations that would continue during the proposed temporary outage, including those of the host railroad and each tenant railroad.
Proposed paragraph (m)(4)(ii)(G) would require the RFA to identify the applicable speed limit of any train that would operate during the proposed temporary outage, and any other operating restrictions in place to ensure rail safety. For example, a properly drafted RFA will outline the railroad's proposed reduced speed for each type of freight train, based on the commodity transported, and each intercity passenger or commuter train, compared to the normal authorized speeds.
Proposed paragraph (m)(4)(ii)(H) would require the railroad to specify in its RFA the additional safety measures that the host railroad and each tenant railroad must comply with during the proposed temporary outage, to ensure each type of PTC-preventable accident or incident does not occur. Specifically, such safety measures must be designed to prevent a train-to-train collision, an over-speed derailment, an incursion into an established work zone, and a movement of a train through a switch left in the wrong position. It is integral that FRA understands exactly how the railroad will mitigate and eliminate the risk of each type of PTC-preventable accident and incident during the short-term PTC system outage. For example, a railroad might propose to utilize an absolute block to mitigate and eliminate the risk of a train-to-train collision, enforce speed limits through the use of other technology, suspend the establishment of work zones, and protect switches through other specific means

For example, a railroad might propose to utilize an absolute block to mitigate and eliminate the risk of a train-to-train collision, enforce speed limits through the use of other technology, suspend the establishment of work zones, and protect switches through other specific means.
Finally, proposed paragraph (m)(4)(ii)(I) would require the railroad to confirm in its RFA that each impacted railroad (including the host railroad and any applicable tenant railroads) will notify all applicable dispatchers, train crews, and roadway workers about the temporary PTC system outage (if FRA authorizes it), including the specific location and duration of the temporary outage, the additional safety measures with which the railroad must comply, and any actions the individual must take during the temporary outage. FRA expects that the proposed specific information an RFA must contain under proposed paragraphs (m)(4)(ii)(A) through (H) would aid the railroad in these notifications. The railroad may make these notifications in accordance with the railroad's operating rules and practices, which may require, for example, such information to be provided via track bulletins, dispatcher bulletins, or special instructions.
Also, FRA notes that its 45-day review-and-decision period under existing paragraph (m) begins when a railroad properly files a complete RFA with all information required under paragraph (m). To be clear, the 45-day clock will not begin on that initial filing date, if an RFA to a PTC system, involving a temporary outage, fails to include any of the contents explicitly required under existing paragraphs (m)(2)(i) through (iv) or the additional content requirements FRA is proposing in paragraphs (m)(4)(ii)(A) through (I)
s a complete RFA with all information required under paragraph (m). To be clear, the 45-day clock will not begin on that initial filing date, if an RFA to a PTC system, involving a temporary outage, fails to include any of the contents explicitly required under existing paragraphs (m)(2)(i) through (iv) or the additional content requirements FRA is proposing in paragraphs (m)(4)(ii)(A) through (I). 22 Instead, consistent with the current § 236.1021(m) process, the 45-day clock begins on the date the railroad or railroads properly submit any remaining information required under existing paragraph (m)(2)(i) through (iv) and proposed paragraphs (m)(4)(ii)(A) through (I). FRA expects this will help ensure a railroad submits a complete RFA, with all required information, in its initial filing.
22 Consistent with FRA's current practice, if an RFA is missing required information, an FRA PTC specialist will contact the railroad via email to inform the railroad of the missing, required content(s).
In addition, FRA acknowledges that it currently publishes a notice in the Federal Register when a railroad submits an RFA to its PTC system under existing § 236.1021(m) and invites public comment on the RFA. See 49 CFR 236.1021(e). During FRA's meeting with labor organizations in February 2024, TTD requested confirmation that FRA will not eliminate the opportunity for the public to comment on these RFAs. FRA confirmed during that Federal Register , and the public will be afforded an opportunity to review and comment on such RFAs. That notice and comment requirement under § 236.1021(e) is outside the scope of this NPRM and will remain part of FRA's regulations. As a reminder, FRA's December 2022 guidance document underscores the importance of ensuring that railroads' filings contain sufficient, non-confidential information for the public to review and on which to comment. 23

Section 236.1029 PTC System Use and Failures
Currently, paragraphs (g)(1) through (3), entitled “Temporary exceptions,” of this section set forth expired regulations. Specifically, existing paragraph (g) indicates that paragraphs (g)(1) through (3) were in effect from October 21, 2014, through December 31, 2022. FRA proposes to replace existing paragraphs (g)(1) through (3) with new provisions that deal directly with initialization failures. FRA's existing regulations, at 49 CFR 236.1003, define “initialization failure” as “any instance when a PTC system fails to activate on a locomotive or train, unless the PTC system successfully activates during a subsequent attempt in the same location or before entering PTC-governed territory.” 24 In relevant part, now-expired paragraph (g)(2) previously permitted any train to continue operating subject to certain speed limits, potentially indefinitely, if a PTC system failed to initialize for any reason
stem fails to activate on a locomotive or train, unless the PTC system successfully activates during a subsequent attempt in the same location or before entering PTC-governed territory.” 24 In relevant part, now-expired paragraph (g)(2) previously permitted any train to continue operating subject to certain speed limits, potentially indefinitely, if a PTC system failed to initialize for any reason.
24 The definition under 49 CFR 236.1003 also clarifies, “For the types of PTC systems that do not initialize by design, a failed departure test is considered an initialization failure for purposes of the reporting requirement under § 236.1029(h), unless the PTC system successfully passes the departure test during a subsequent attempt in the same location or before entering PTC-governed territory.”
FRA recognizes that unplanned outages and other technical issues continue to occur, causing PTC systems to fail to initialize, based on FRA's oversight and railroads' Quarterly Reports of PTC System Performance. 25 Railroads' Quarterly Reports of PTC System Performance show, for example, that PTC technology failed to initialize on approximately 236 intercity passenger or commuter trains and 894 freight trains in 2023. 26 Additionally, FRA, based on voluntary reporting by railroads, is aware of eight (8) system-level outages that occurred in 2023 that caused trains to fail to initialize.
25 Form FRA F 6180.152, OMB Control No. 2130-0553; 49 U.S.C. 20157(m).
26 The referenced initialization failures exclude any initialization failures where the source or cause was the onboard subsystem, as proposed paragraph (g)(3) excludes such initialization failures from receiving the flexibility afforded under proposed paragraph (g). FRA is citing to the relevant initialization failures where the source or cause was, for example, the back office, wayside, or communications subsystems because those types of issues would generally impact more than one train and would be within the scope of this proposed provision
ph (g)(3) excludes such initialization failures from receiving the flexibility afforded under proposed paragraph (g). FRA is citing to the relevant initialization failures where the source or cause was, for example, the back office, wayside, or communications subsystems because those types of issues would generally impact more than one train and would be within the scope of this proposed provision.
During FRA's meetings in November 2023 and February 2024, AAR, APTA, ASLRRA, CRC, and many railroads 27 conveyed strong support for FRA's proposal to reintroduce requirements analogous to the provision that expired in 2022. Consistent with FRA's own observations, AAR, APTA, ASLRRA, CRC, and their member railroads underscored the need for FRA to establish a process to enable railroads to continue operating safely, following certain initialization failures, because otherwise freight, intercity passenger, and commuter trains will be unable to depart from their initial terminals or other locations and provide necessary transportation.
27 Including, for example, Alaska Railroad, Amtrak, BNSF, Caltrain, CN, CPKC, CSX, Denver RTDC, G&W, MARC, MBTA, Metra, Metrolink, NICD, NJT, NS, OmniTRAX, TEXRail, TRE, UP, UTA FrontRunner, VRE, and Watco.
Specifically, FRA's intention in this NPRM is to address only system-level outages or failures that result in multiple trains' PTC systems failing to initialize, like when a back office server goes down, impacting the trains of the host railroad and most, if not all, of its tenant railroads. Accordingly, FRA proposes to provide a caveat in proposed paragraph (g)(4), which would specify that the relief under paragraph (g)(1), discussed below, does not apply to a single train that experiences an onboard PTC system failure when attempting to initialize. The purpose of proposed paragraph (g) is to address issues affecting multiple trains
road and most, if not all, of its tenant railroads. Accordingly, FRA proposes to provide a caveat in proposed paragraph (g)(4), which would specify that the relief under paragraph (g)(1), discussed below, does not apply to a single train that experiences an onboard PTC system failure when attempting to initialize. The purpose of proposed paragraph (g) is to address issues affecting multiple trains.
During FRA's meeting with labor organizations in February 2024, BLET, BRS, and TTD acknowledged that FRA's objective in proposed paragraph (g) is to enable operations while maintaining rail safety, but they expressed concern for the potential unintended consequence of degrading safety or delaying repairs to PTC technology. FRA agrees that it is important to structure proposed paragraph (g) to ensure railroads, vendors, and suppliers identify and fix any issues causing initialization failures immediately.
To ensure this provision is utilized only when necessary and railroads and their vendors and suppliers identify and promptly resolve the root cause of initialization failures, FRA is proposing to impose two tiers of operating requirements that would become increasingly restrictive over time. FRA expects this will help strike the appropriate balance between enabling continued operations, subject to restrictions, and restoring PTC systems as quickly as possible.
First, proposed paragraph (g)(1)(i) provides that when a PTC system fails to initialize as defined in § 236.1003, a train may proceed, during the first 24 hours, only as prescribed under existing paragraphs (b)(1) through (6) of § 236.1029. FRA is proposing to require railroads to utilize the current operating restrictions set forth in existing paragraphs (b)(1) through (6) because railroads, including train crews, are accustomed to complying with those speed limits and other restrictions when they experience en route failures, and those restrictions are based on the underlying signal or train control system still in effect
236.1029. FRA is proposing to require railroads to utilize the current operating restrictions set forth in existing paragraphs (b)(1) through (6) because railroads, including train crews, are accustomed to complying with those speed limits and other restrictions when they experience en route failures, and those restrictions are based on the underlying signal or train control system still in effect. During FRA's meetings, the following railroads explicitly recommended this approach, based on industry's longstanding use of these operating restrictions when PTC technology fails or is otherwise cut out en route: Alaska Railroad, Amtrak, BNSF, CN, CPKC, CSX, G&W, MARC, Metra, Metrolink, NICD, NS, and UP.
Second, proposed paragraph (g)(1)(ii) states that after the first 24 hours, the train may proceed only as prescribed under paragraphs (b)(4) through (6) of this section and must not exceed restricted speed as defined in § 236.1003. FRA proposes to require compliance with existing paragraphs (b)(4) through (6) as they contain other applicable restrictions and communication requirements. 28 However, instead of the standard speed restrictions under existing paragraph (b), this stricter tier of operating restrictions would limit any train that utilizes this provision beyond 24 hours to restricted speed, which is defined as a “speed that will permit stopping 29

During FRA's meetings with APTA, CRC, and their member railroads in February 2024, several commuter railroads, including Denver RTD, MARC, Metra, NICD, NJT, TEXRail, TRE, and UTA FrontRunner supported FRA's intention to propose a two-tiered framework. For example, MARC and NICD noted that the unplanned outages they recently experienced were resolved in approximately two hours, which means those trains, in a similar scenario under this proposed framework, would be subject to the standard operating restrictions under existing paragraph (b). Furthermore, these commuter railroads expressed appreciation that this proposed framework—with more flexibility on day one—would enable them to transport commuters to their destination if PTC technology fails midday and trains are unable to initialize the PTC system for the remainder of the day. Without this proposed provision, if a train's PTC system fails midday and is not restored by the evening rush hour, commuters attempting to return home would be forced to rely on alternative modes of transportation, with little to no notice.
These eight commuter railroads also recognized that a clear, tiered approach—which introduces additional restrictions, including restricted speed, 24 hours after the onset of the technical issue—would enable railroads to communicate effectively with their customers if the railroad finds that an issue cannot be remedied within the first 24 hours

These eight commuter railroads also recognized that a clear, tiered approach—which introduces additional restrictions, including restricted speed, 24 hours after the onset of the technical issue—would enable railroads to communicate effectively with their customers if the railroad finds that an issue cannot be remedied within the first 24 hours. Commuter railroads emphasized the importance of being able to provide advance notice to their customers about the speed restrictions that would apply the following day, as that could result in service reductions.
Several stakeholders, including ASLRRA, ATD, NJT, and UTA FrontRunner, stressed that the operating restrictions FRA proposes in paragraph (g) should be as simple, straightforward, and objective as possible given the complexity of other PTC regulations. Furthermore, FRA recognizes that predictability and transparency are vital when it comes to a process that will govern whether and how intercity passenger, commuter, and freight rail transportation may continue.
Proposed paragraph (g)(2) imposes a notification requirement that a railroad must, as early as is possible, ensure workers are aware of PTC system-level outages and corresponding operating restrictions. Specifically, proposed paragraph (g)(2) requires each railroad operating in accordance with (g)(1) to notify, as early as is possible, all dispatchers, train crews, and roadway workers about PTC system-level outages or failures that result in multiple trains' PTC systems failing to initialize, which result in trains proceeding in accordance with operating restrictions. Railroads must ensure job safety briefings reflect such operations.
Proposed paragraph (g)(3) proposes to require railroads to attempt to initialize the PTC system again, when the reason it is not initializing is loss of communications or lack of navigational information, like temporary lack of access to the Global Positioning System (GPS) TM

Proposed paragraph (g)(3) proposes to require railroads to attempt to initialize the PTC system again, when the reason it is not initializing is loss of communications or lack of navigational information, like temporary lack of access to the Global Positioning System (GPS) TM . FRA is aware of multiple PTC systems that rely on GPS, like I-ETMS and the Incremental Train Control System. Specifically, proposed paragraph (g)(3) would require, notwithstanding the relief under paragraph (g)(1), that when a PTC system fails to initialize due to loss of communications or lack of navigational information, the train must attempt to initialize the PTC system again at the next forward, available location. The next forward, available location, depending on the circumstances, could be a segment of a main line, a siding, a yard, or a station, whichever is closest.
In addition, FRA acknowledges that PTC systems are comprised of many subsystems and are often interfaced with other technology. For example, at an AAR meeting in November 2023, CN emphasized that the nature of a system of subsystems, like PTC technology, means there is always the possibility of an outage, as a PTC system relies or depends on the proper functioning of many subsystems. Similarly, FRA is also aware that PTC systems have failed to initialize due to a failure of an interfaced system, like a dispatching system or an electronic storage system. Accordingly, FRA wants to clarify that proposed paragraphs (g)(1) through (5) of this section likewise apply to cases in which a PTC system fails to initialize due to an issue or failure arising from a subsystem or an interfaced system.
In addition, FRA wants to offer a clarification about the application of proposed paragraphs (g)(1) to (5) to the Advanced Civil Speed Enforcement System II (ACSES II)
ingly, FRA wants to clarify that proposed paragraphs (g)(1) through (5) of this section likewise apply to cases in which a PTC system fails to initialize due to an issue or failure arising from a subsystem or an interfaced system.
In addition, FRA wants to offer a clarification about the application of proposed paragraphs (g)(1) to (5) to the Advanced Civil Speed Enforcement System II (ACSES II). An initialization failure is defined in existing § 236.1003 as “any instance when a PTC system fails to activate on a locomotive or train, unless the PTC system successfully activates during a subsequent attempt in the same location or before entering PTC-governed territory.” Section 236.1003 specifies that for the types of PTC systems that do not initialize by design, like ACSES II, a failed departure test is considered an initialization failure, unless the PTC system successfully passes the departure test during a subsequent attempt in the same location or before entering PTC-governed territory. ACSES II typically encompasses automatic train control (ATC), and FRA wants to emphasize that the FRA-certified PTC system, however, is ACSES II. 30 If ACSES II fails to initialize ( i.e., fails its departure test), an ACSES II-equipped train may utilize the relief outlined in proposed paragraph (g) of § 236.1029. By contrast, however, if ATC fails its departure test, a railroad must comply with all applicable signal and train control prohibitions and restrictions in other subparts of part 236. FRA wants to address this nuance to clarify that proposed paragraph (g) does not supersede other existing signal and train control regulations that directly govern ATC.
30 Or in NJT's case, the Advanced Speed Enforcement System II (ASES II).
Finally, proposed paragraph (g)(5) recognizes that FRA may impose additional operating restrictions and other conditions to address recurring issues that result in multiple trains' PTC systems failing to initialize
ragraph (g) does not supersede other existing signal and train control regulations that directly govern ATC.
30 Or in NJT's case, the Advanced Speed Enforcement System II (ASES II).
Finally, proposed paragraph (g)(5) recognizes that FRA may impose additional operating restrictions and other conditions to address recurring issues that result in multiple trains' PTC systems failing to initialize. For example, under proposed paragraph (g)(5), FRA could require the applicable railroads and PTC system vendors and suppliers to take certain actions or satisfy additional reporting requirements, as they resolve the recurring issues. In addition, proposed paragraph (g)(4) would clarify that FRA reserves the right to deny the relief under proposed paragraph (g)(1) for recurring issues that result in multiple trains' PTC systems failing to initialize. Although the relief under proposed paragraph (g)(1) is generally self-executing, FRA may choose to intervene under proposed paragraph (g)(5) and deny such relief if, for example, a railroad and/or its applicable PTC system vendor and supplier are not sufficiently correcting a recurrent problem.

In this analysis, discount rates are used to account for differences in the timing of the estimated benefits and costs. Benefits and costs that accrue further in the future are more heavily discounted than those impacts that occur today. Discounting reflects individuals' general preference to receive benefits sooner rather than later (and defer costs) and recognizes that costs incurred today are more expensive than future costs because businesses must forgo an expected rate of return on investment of that capital. 33 OMB recommends using a discount rate of 2 percent. 34 This represents the real (inflation-adjusted) rate of return on long-term Federal Government debt over the last 30 years, calculated between 1993 and 2022, and is considered a reasonable approximation of the social rate of time preference.

FRA analyzed the economic impact of this proposed rule over a 10-year period and estimated its costs and benefits, as shown in the table below. The total estimated 10-year net benefits of this proposed rule would be $81.8 million (discounted at 2 percent), and the annualized net benefits would be $9.1 million (discounted at 2 percent). The industry benefits associated with FRA's proposal to amend three provisions— i.e., to introduce a new exception for certain non-revenue passenger equipment movements, improve the RFA process regarding temporary PTC system outages, and permit continued operations following certain initialization failures, subject to operating restrictions—would outweigh the industry costs and government administrative costs associated with FRA's proposal to expand the content requirements for RFAs related to temporary outages.
The following table shows the estimated 10-year benefits, net benefits, and costs of the proposed rule. The total 10-year estimated benefits would be $83.5 million (discounted at 2 percent), with annualized benefits at $9.3 million (discounted at 2 percent). The total 10-year estimated costs would be $1.8 million (discounted at 2 percent), with annualized costs at $0.2 million (discounted at 2 percent).

The present value of costs and benefits are calculated in this analysis. Present value provides a way of converting future benefits into equivalent dollars today. The formula used to calculate the present value at the particular discount rate is: 1/(1+r) t , where “r” is the discount rate, and “t” is the year. Discount rates of 2%, 3%, and 7% are used in this analysis. 2 Total Costs = Industry Costs + Government Administrative Costs. 3 Net Benefits = Industry Benefits—(Industry Costs + Government Administrative Costs). FRA notes that the net industry benefits of this proposed rule may help reduce the overall industry costs for implementing and operating PTC systems. 1. Ten-Year Benefits
Proposed 49 CFR 236.1006(b)(6)
FRA analyzed the potential industry benefits of the three proposed amendments. Overall, the three proposed amendments would benefit the railroad industry, the public, and FRA by facilitating repairs, maintenance, upgrades, and capital improvements; expanding certain railroad informational requirements; reducing costs; and enabling the safe, reliable, and resilient movement of people and goods, while preserving rail safety.
The proposed exception under § 236.1006(b)(6) would enable non-revenue passenger equipment, including a locomotive, locomotive consist, or train without passengers onboard, to operate to a maintenance facility or yard for the sole purpose of repairing or exchanging a PTC system
ucing costs; and enabling the safe, reliable, and resilient movement of people and goods, while preserving rail safety.
The proposed exception under § 236.1006(b)(6) would enable non-revenue passenger equipment, including a locomotive, locomotive consist, or train without passengers onboard, to operate to a maintenance facility or yard for the sole purpose of repairing or exchanging a PTC system. To ensure rail safety, FRA is proposing to impose five conditions on each movement of non-revenue passenger equipment subject to this exception, including speed and distance restrictions, the requirement to establish an absolute block, and other protections of the route.
In assessing the potential benefits of the proposed provision, FRA focused on the impact on train operations in the absence of this proposed rule. The methodology employed involved estimating the transportation costs associated with relocating non-operative, PTC-equipped passenger equipment to a maintenance facility or yard to repair or exchange the PTC technology. For example, without this proposed provision, intercity passenger railroads and commuter railroads would need to use an operative, PTC-equipped locomotive, locomotive consist, or train to move the non-operative, PTC-equipped equipment to a maintenance facility or yard.
Based on consultation with FRA subject matter experts, FRA calculated the potential benefits for train operations, under proposed § 236.1006(b)(6), by multiplying the expected number of impacted passenger equipment by the transportation cost of moving that equipment to a maintenance facility or yard. FRA estimated a range of $3,000 to $4,000 to transport this type of equipment, or an average cost of $3,500 per piece of equipment, similar to the amount utilized in another FRA NPRM 35 to estimate the transportation cost of moving an empty car

FRA estimated a range of $3,000 to $4,000 to transport this type of equipment, or an average cost of $3,500 per piece of equipment, similar to the amount utilized in another FRA NPRM 35 to estimate the transportation cost of moving an empty car. FRA estimates that the transportation cost savings of moving this equipment is the estimated number of non-revenue passenger equipment that may use this proposed exception ( i.e., 30 per year or 1 per intercity passenger or commuter railroad 36 ), multiplied by the expected transportation cost of $3,500, resulting in an overall transportation cost savings of $105,000 annually. Given the uncertainty about the amount of affected equipment and the five safety conditions or restrictions that FRA is proposing a railroad must comply with while utilizing this exception, FRA is seeking input from the public on whether the cost of these five safety conditions, which FRA did not calculate due to insufficient data, might reduce the calculated net benefits.

Under proposed § 236.1021(m)(4), a railroad seeking to temporarily disable its PTC system, for certain purposes, can request FRA's approval through the standard RFA process under existing § 236.1021(m). There have been no accidents or incidents associated with railroads' RFAs for temporary PTC system outages from 2022 to early 2024, the relevant period during which FRA began approving such outages by regulation.
Based on past RFA filings from 2022 to early 2024 involving temporary PTC system outages, FRA estimates that railroads will file approximately 15 RFAs, on average on an annual basis, under proposed § 236.1021(m)(4) in the future. FRA estimates that two-thirds of railroads' RFAs would involve a PTC system outage lasting for a few hours, while one-third would seek to disable PTC technology for a period of days, given the different nature of underlying capital improvement or maintenance projects
imates that railroads will file approximately 15 RFAs, on average on an annual basis, under proposed § 236.1021(m)(4) in the future. FRA estimates that two-thirds of railroads' RFAs would involve a PTC system outage lasting for a few hours, while one-third would seek to disable PTC technology for a period of days, given the different nature of underlying capital improvement or maintenance projects. FRA used the Bureau of Transportation Statistics' (BTS) 2021 fare rates for intercity passenger and commuter rail transportation— i.e., a $72.10 average rate for Amtrak and a $6.30 average rate for commuter railroads. FRA estimated weighted fare rates by using those average 2021 BTS fare rates and analyzing past, pertinent RFAs to estimate that the average fare rate would be approximately $11 for each intercity passenger railroad or commuter railroad that submits an RFA pursuant to § 236.1021(m)(4) in the future. 37
37 U.S. Department of Transportation, Bureau of Transportation Statistics, Transportation Economic Trends (2022), available at https://data.bts.gov/stories/s/5h3f-jnbe#transportation-fares.
Similarly, FRA analyzed the average number of passengers or commuters per train movement 38 during a temporary PTC system outage by analyzing past RFAs and found that each train carries, on average, approximately 200 passengers or commuters. Likewise, FRA analyzed the average number of train movements during a temporary PTC system outage by analyzing past RFAs and estimating the expected number of filings by type of railroad. Based on past RFAs, FRA estimates that on average, 5 trains operate during a freight railroad's temporary PTC system outage; 12 trains operate during an intercity passenger or commuter railroad's PTC system outage that lasts 24 hours or less; and 1,700 trains operate during an intercity passenger or commuter railroad's PTC system outage that lasts longer (days). For freight railroads, the average cost per train movement is $250, based on previous FRA estimates
ate during a freight railroad's temporary PTC system outage; 12 trains operate during an intercity passenger or commuter railroad's PTC system outage that lasts 24 hours or less; and 1,700 trains operate during an intercity passenger or commuter railroad's PTC system outage that lasts longer (days). For freight railroads, the average cost per train movement is $250, based on previous FRA estimates.
38 By “train movement,” FRA is referring to the movement or operation of a train.
Then, the expected annual number of RFAs, involving temporary PTC system outages, is multiplied by: (1) the average number of train movements during the temporary outage; (2) the average cost per fare or train movement; and (3) the average number of passengers or commuters per train (for intercity passenger or commuter railroads), and is then adjusted for reduced speed. 39 As shown in the tables below, the 15 relevant RFAs that FRA expects to receive annually would result in $8,578,734 in total benefits, undiscounted, per year. FRA notes this 40 Additionally, FRA is seeking comments on this economic analysis, its underlying assumptions, and any additional benefits that could be quantified, like the potential impact to ridership from avoiding related train delays or cancelations.
39 In its decision letters approving such RFAs, FRA typically requires railroads to comply with the operating restrictions under 49 CFR 236.1029(b), which limit the speed of trains depending on the underlying signal or train control system.

The proposed exception under § 236.1029(g) would reintroduce a revised version of a provision regarding PTC system initialization failures that expired on December 31, 2022. This proposed exception would be beneficial even with the conditions and restrictions outlined under this proposed provision.
In assessing the potential benefits of this proposed provision, FRA focused on the impact on train operations in the absence of this proposed rule. Currently, if a PTC system fails to initialize, trains are generally prohibited from operating, which could result in situations where passengers are stranded and vital freight shipments halted, as the prior regulatory process expired on December 31, 2022. Based on consultation with FRA subject matter experts, FRA estimates the number of future PTC system initialization failures by analyzing railroads' initialization failures in calendar year 2023, as reported to FRA in railroads' Quarterly Reports of PTC System Performance 41 and projecting to the future. In total, based on past data, FRA expects freight railroads to experience approximately 900 initialization failures per year and intercity passenger or commuter railroads to experience approximately 200 initialization failures per year in the future. 42 Then, the expected annual number of initialization failures is multiplied by: (1) the average cost of $11 per fare for intercity passenger or

42 The estimated 1,100 initialization failures exclude any initialization failures where the source or cause is the onboard subsystem, as proposed § 236.1029(g)(3) excludes such initialization failures from receiving the flexibility afforded under proposed § 236.1029(g), as they typically impact one train. FRA's estimate refers to the number of initialization failures where the source or cause is, for example, the back office, wayside, or communications subsystems because those types of issues would generally impact more than one train and would be within the scope of this proposed provision.
As shown in the table below, FRA's proposal to permit the operation of approximately 1,100 trains that FRA expects might experience PTC system initialization failures would result in $433,520 in total benefits, undiscounted, per year. FRA notes this calculation did not include variable operating costs such as fuel expenses and other operational costs. Therefore, the estimated benefit could be reduced by these variable operating costs, although the exact amount is unclear. Additionally, FRA is seeking comments on this economic analysis, its underlying assumptions, and any additional benefits that could be quantified, like the potential impact on ridership from avoiding related train delays or cancelations

For example, there are possible fuel and emission savings from people not using alternative transportation modes like traditional buses or cars that use fuel or non-carbon technologies like batteries, which would be necessary if the proposals in this NPRM did not exist, and railroads were not allowed to operate trains in certain circumstances. Freight trains are generally known for their fuel efficiency compared to fuel-powered trucks, and intercity passenger or commuter trains are more efficient than driving fuel-powered vehicles, potentially resulting in lower carbon emissions. Specifically, a single freight train can be up to 75% more fuel-efficient than a fuel-powered truck. 43 Similarly, passenger trains are up to 46% more efficient than driving fuel-powered vehicles. 44 However, policies promoting electric vehicle use may lead to increased adoption of electric vehicles, which could reduce the anticipated emission benefits.

2. Ten-Year Costs
FRA analyzed the potential industry costs of the proposed amendments, which would: (1) permit non-revenue passenger equipment to operate to maintenance facilities or yards, without being governed by PTC technology and with no passengers onboard, for the sole purpose of repairing or exchanging a PTC system, under certain conditions; (2) improve the existing process railroads utilize to request and obtain FRA's approval to disable their PTC systems temporarily—when necessary to facilitate repair, maintenance, infrastructure upgrades, and capital projects—by requiring railroads to provide additional, essential
Of the three proposed amendments, FRA analyzed the cost of railroads filing RFAs regarding temporary PTC system outages under proposed § 236.1021(m)(4), which contains additional content requirements to enable FRA to assess the full scope and circumstances of each proposed temporary outage. Since the other two proposed provisions, under §§ 236.1006(b)(6) and 236.1029(g), would establish an exception or process with certain conditions, there may be minimal potential costs tied to these proposed provisions. However, FRA expects the potential benefits of these proposed provisions to outweigh any potential costs they might present. FRA welcomes comments on the potential impact.
Also, FRA acknowledges that a proposal to establish a new exception for non-revenue passenger equipment and reintroduce a limited version of an expired process might appear to present safety risks, if not properly addressed

Also, FRA acknowledges that a proposal to establish a new exception for non-revenue passenger equipment and reintroduce a limited version of an expired process might appear to present safety risks, if not properly addressed. Accordingly, FRA's proposed rule contains multiple operating restrictions and other protections to help mitigate or eliminate any associated risks and help preserve or improve rail safety.
Based on consultation with FRA subject matter experts, FRA calculated the total cost for filing an RFA by multiplying the number of submissions by its associated hourly burden. The hourly burden is then multiplied by the wage rate of an Executive, Official, & Staff Assistant employee. For this analysis, FRA used the fully burdened wage rate of $118.46 to calculate both costs ( i.e., the cost of submitting a new RFA and the cost of submitting a revised RFA). 45 This wage rate includes factors such as salary, benefits, and overhead costs associated with employing staff members involved in the RFA filing process.
45 Throughout this document, the dollar equivalent cost or benefit for the industry is derived from the Surface Transportation Board's 2023 Full Year Wage A&B data series using the appropriate employee group hourly wage rate, which includes an additional 75 percent for fringe benefits and overhead. For instance, the 2023 hourly wage rate of $67.69 is burdened by 75 percent ($67.69 × 1.75 = $118.46)

Results
The industry benefits associated with FRA's proposal to amend three provisions— i.e., to introduce a new exception for certain non-revenue passenger equipment movements, improve the RFA process regarding temporary PTC system outages, and permit continued operations following certain initialization failures, subject to operating restrictions—would outweigh the industry costs and government administrative costs associated with FRA's proposal to expand the content requirements for RFAs related to temporary outages.
The following table shows the estimated 10-year costs, benefits, and net benefits of the proposed rule. The total estimated 10-year net benefits would be $81.8 million (discounted at 2 percent) and annualized net benefits would be $9.1 million (discounted at 2 percent)

Regulatory Flexibility Act and Executive Order 13272
The Regulatory Flexibility Act of 1980 (5 U.S.C. 601, et seq. ) and Executive Order 13272, “Proper Consideration of Small Entities in Agency Rulemaking,” (67 FR 53461 (Aug. 16, 2002)) require agency review of proposed and final rules to assess their impacts on small entities. An agency must prepare an Initial Regulatory Flexibility Analysis (IRFA) unless it determines and certifies that a rule, if promulgated, would not have a significant economic impact on a substantial number of small entities. FRA has not determined whether this proposed rule would have a significant economic impact on a substantial number of small entities.
FRA invites all interested parties to submit comments, data, and information demonstrating the potential economic impact on small entities that will result from the adoption of this proposed rule. FRA particularly encourages small entities potentially impacted by the proposed amendments to participate in the public comment process
ficant economic impact on a substantial number of small entities.
FRA invites all interested parties to submit comments, data, and information demonstrating the potential economic impact on small entities that will result from the adoption of this proposed rule. FRA particularly encourages small entities potentially impacted by the proposed amendments to participate in the public comment process. FRA will consider all comments received during the public comment period for this NPRM when making a final determination of the rule's economic impact on small entities. FRA prepared an IRFA, which is included below, to aid the public in commenting on the potential small business impacts of the proposed requirements in this NPRM.
1. Reasons for Considering Agency Action
Through FRA's oversight and continued engagement with the industry, FRA has found that its existing PTC regulations do not adequately address temporary situations during which PTC technology is not enabled, including after certain initialization failures or in cases where a PTC system needs to be temporarily disabled to facilitate repair, maintenance, infrastructure upgrades, or capital projects. This NPRM proposes to establish parameters and operating restrictions under which railroads may continue to operate safely in certain scenarios when PTC technology is temporarily not governing rail operations. Overall, the proposed amendments would benefit the railroad industry, the public, and FRA by facilitating repairs, maintenance, upgrades, and capital improvements; expanding certain railroad informational requirements; reducing costs; and enabling the safe, reliable, and efficient movement of people and goods, while preserving rail safety.
2. A Succinct Statement of the Objectives of, and the Legal Basis for, the Proposed Rule
FRA is proposing to revise three PTC regulations based on the statutory general authority of the Secretary
capital improvements; expanding certain railroad informational requirements; reducing costs; and enabling the safe, reliable, and efficient movement of people and goods, while preserving rail safety.
2. A Succinct Statement of the Objectives of, and the Legal Basis for, the Proposed Rule
FRA is proposing to revise three PTC regulations based on the statutory general authority of the Secretary. The Secretary has broad statutory authority to “prescribe regulations and issue orders for every area of railroad safety” under 49 U.S.C. 20103 and regarding PTC technology under 49 U.S.C. 20157(g). The Secretary delegated this authority to the Federal Railroad Administrator. 49 CFR 1.89(b).
This proposed rule would provide flexibility to certain train movements and improve existing processes, which would result in net benefits to railroads. The industry benefits associated with FRA's proposal to amend §§ 236.1006(b), 236.1021(m) and 236.1029(g)— i.e., to introduce a new exception for certain non-revenue passenger equipment movements, improve the RFA process regarding temporary PTC system outages, and permit continued operations following certain initialization failures, subject to operating restrictions—would outweigh the industry costs and government administrative costs associated with FRA's proposal to expand the content requirements for RFAs related to temporary outages under § 236.1021(m), while also maintaining rail safety.
FRA's objective in this rulemaking is to establish clear, uniform processes, rather than addressing issues that arise in a reactive and piecemeal manner. FRA expects that establishing predictable, prescriptive processes will both enable continued operations and improve railroad safety by eliminating uncertainty and inconsistent application of FRA's regulations and facilitating prompt repairs, upgrades, and restoration of PTC system service
tablish clear, uniform processes, rather than addressing issues that arise in a reactive and piecemeal manner. FRA expects that establishing predictable, prescriptive processes will both enable continued operations and improve railroad safety by eliminating uncertainty and inconsistent application of FRA's regulations and facilitating prompt repairs, upgrades, and restoration of PTC system service. FRA's proposed parameters and operating restrictions in this NPRM are intended to be sufficiently strict to ensure that railroads and PTC system suppliers and vendors proactively identify and remedy problems before they arise and immediately correct any problems that may surface despite proactive measures.
3. A Description of and, Where Feasible, an Estimate of the Number of Small Entities to Which the Proposed Rule Would Apply
The Regulatory Flexibility Act of 1980 requires a review of proposed and final rules to assess their impact on small entities, unless the Secretary certifies that the rule would not have a significant economic impact on a substantial number of small entities. “Small entity” is defined in 5 U.S.C. 601 as a small business concern that is independently owned and operated and is not dominant in its field of operation. The U.S. Small Business Administration (SBA) has authority to regulate issues related to small businesses, and stipulates in its size standards that a “small entity” in the railroad industry is a for-profit “line-haul railroad” that has fewer than 1,500 employees, a “short line railroad” with fewer than 500 employees, or a “commuter rail system” with annual receipts of less than seven million dollars.
