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 June 7, 
2024, Metrolink submitted an RFA to its Interoperable Electronic Train 
Management System (I-ETMS), which seeks FRA's approval of a temporary 
I-ETMS outage to support pre-revenue service vehicle acceptance testing 
on a new vehicle type. That RFA is available in Docket No. FRA-2010-
0048.
    Interested parties are invited to comment on Metrolink'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.

Privacy Act Notice

    In accordance with 49 CFR 211.3, FRA solicits comments from the
