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.
