DEPARTMENT OF TRANSPORTATION
Federal Railroad Administration
[Docket Number FRA-2010-0039]
South Florida Regional Transportation Authority's Request To
Amend Its Positive Train Control Safety Plan and Positive Train Control
System
AGENCY: Federal Railroad Administration (FRA), Department of
Transportation (DOT).
ACTION: Notice of availability and request for comments.
-----------------------------------------------------------------------
SUMMARY: This document provides the public with notice that, on July 8,
2025, the South Florida Regional Transportation Authority (SFRV)
submitted a request for amendment (RFA) to its FRA-certified Positive
Train Control Safety Plan (PTCSP) and positive train control (PTC)
system, seeking FRA's approval to temporarily disable its PTC system
between Milepost (MP) SX1015.82 and MP SX1022.29 for a planned signal
cutover that will last approximately two days and six hours, between
September 19, 2025, and September 22, 2025. As this RFA may involve a
request for FRA's approval of proposed material modifications to an
FRA-certified PTC system, FRA is publishing this notice, and inviting
public comment on SFRV's RFA to its PTC system.
DATES: FRA will consider comments received by August 5, 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-2010-0039. 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.

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 of a signal or train control
system. Accordingly, this notice informs the public that, on July 8,
2025, SFRV submitted an RFA to its PTCSP for its Interoperable
Electronic Train Management System, which seeks FRA's approval to
temporarily disable its PTC system for approximately two days and six
hours to upgrade end of life wayside signal operating equipment between
MP SX1015.82 and MP SX1022.29. That RFA is available in Docket No. FRA-
2010-0039.
Interested parties are invited to comment on SFRV's RFA by
submitting written comments or data. During FRA's review of SFRV'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.
