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, October 3, 
2025, Amtrak submitted two RFAs to its I-ETMS PTC system which seeks 
FRA's approval for regular quarterly and biannual PTC outages to 
perform I-ETMS back office subsystem stability and reliability upgrades 
through December 2030. The outages will last approximately two (2) 
hours but not to exceed three (3) hours quarterly, and approximately 
three (3) hours but not to exceed four (4) hours biannually. Those RFAs 
are available in Docket No. FRA-2010-0029.
    Interested parties are invited to comment on Amtrak's RFAs by 
submitting written comments or data. During FRA's review of these 
railroad's RFAs, 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.
