[Docket Number FRA-2010-0029]


Amtrak's Request To Amend Its Positive Train Control System

AGENCY: Federal Railroad Administration (FRA), Department of 
Transportation (DOT).

ACTION: Notice of extension of comment period.

-----------------------------------------------------------------------

SUMMARY: On April 28, 2025, FRA published a notice of availability and 
request for comments about the request for amendment (RFA) that the 
National Railroad Passenger Corporation (Amtrak) submitted on April 16, 
2025. Amtrak's RFA requests authorization to temporarily disable one of 
its FRA-certified positive train control (PTC) systems for a period of 
one to two hours in support of the installation and testing of a new 
Back Office Subsystem environment upgrade. FRA is publishing this 
notice to extend the comment period, which would otherwise end on May 
19, 2025, to May 30, 2025, due to a technical docket issue that 
occurred at the time of publication of the first notice.

DATES: The comment period for the document published April 28, 2025 at 
90 FR 17686 is extended. FRA will consider comments received by May 30, 
2025. FRA may consider comments received after that date to the extent 
practicable and without delaying implementation of valuable or 
necessary modifications to a PTC system.

ADDRESSES: Comments: Comments may be submitted by going to https://www.regulations.gov and following the online instructions for 
submitting comments.
    Instructions: All submissions must include the agency name and the 
applicable docket number. The relevant PTC docket number for this host 
railroad is Docket No. FRA-2010-0029. For convenience, all active PTC 
dockets are hyperlinked on FRA's website at https://railroads.dot.gov/research-development/program-areas/train-control/ptc/railroads-ptc-dockets. All comments received will be posted without change to https://www.regulations.gov; this includes any personal information.

FOR FURTHER INFORMATION CONTACT: Gabe Neal, Staff Director, Signal, 
Train Control, and Crossings Division, telephone: 816-516-7168, email: 
[email protected].

SUPPLEMENTARY INFORMATION: In general, title 49 United States Code 
(U.S.C.), section 20157(h) requires FRA to certify that a host 
railroad's PTC system complies with title 49 Code of Federal 
Regulations (CFR), part 236, subpart I, before the technology may be 
operated in revenue service. Before making certain changes to an FRA-
certified PTC system or the associated FRA-approved PTC Safety Plan 
(PTCSP), a host railroad must submit, and obtain FRA's approval of, an 
RFA to its PTC system or PTCSP under 49 CFR 236.1021.
    Under 49 CFR 236.1021(e), FRA's regulations provide that FRA will 
publish a notice in the Federal Register and invite public comment in 
accordance with 49 CFR part 211, if an RFA includes a request for 
approval of a material modification or discontinuance of a signal or 
train control system. Accordingly, this notice informs the public that, 
on April 16, 2025, Amtrak submitted an RFA to its Interoperable 
Electronic Train Management System (I-ETMS). Amtrak seeks FRA's 
approval to disable its I-ETMS temporarily, for one to two hours, to 
support the installation and testing of a new Back Office Subsystem 
environment upgrade in June 2025. Amtrak asserts that this new 
environment will support improved I-ETMS operations reliability. That 
RFA is available in Docket No. FRA-2010-0029.
    Interested parties are invited to comment on Amtrak's RFA by 
submitting written comments or data. During FRA's review of this 
railroad's RFA, FRA will consider any comments or data submitted within 
the timeline specified in this notice and to the extent practicable, 
without delaying implementation of valuable or necessary modifications 
to a PTC system. See 49 CFR 236.1021; see also 49 CFR 236.1011(e). 
Under 49 CFR 236.1021, FRA maintains the authority to approve, approve 
with conditions, or deny a railroad's RFA at FRA's sole discretion.
