Control System

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

ACTION: Notice of availability and request for comments.

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

SUMMARY: This document provides public notice that, on August 11, 2025, 
Long Island Rail Road (LIRR) submitted a request for amendment (RFA) to 
its FRA-certified positive train control (PTC) system. FRA is 
publishing this notice and inviting public comment on the railroad's 
RFA to its PTC system.

DATES: FRA will consider comments received by September 11, 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-2010-0031. 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, 49 U.S.C. 20157(h) requires FRA 
to certify that a host railroad's PTC system complies with 49 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 of a signal or train control 
system. Accordingly, this notice informs the public that, on August 11, 
2025, LIRR submitted an RFA to its PTCSP for its Advanced Civil Speed 
Enforcement System II (ACSES II), seeking FRA's approval to disable 
ACSES II temporarily to facilitate the installation, testing, and 
commissioning of modifications to certain transponders, wayside 
interface units, and the back office map. That RFA is available in 
Docket No. FRA-2010-0031.
    Interested parties are invited to comment on LIRR'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.
