SUMMARY: This document provides the public with notice that, on July 
25, 2025, 21 host railroads submitted a joint request for amendment 
(RFA) to their FRA-approved Positive Train Control Safety Plans (PTCSP) 
to implement onboard software Version 6.5.5.0, which would require 
modifications to the Interoperable Train Control (ITC) Positive Train 
Control (PTC) Concept of Operations and to the human-machine interface 
(HMI). As this joint RFA may involve requests for FRA's approval of 
proposed material modifications to FRA-certified PTC systems, FRA is 
publishing this notice and inviting public comment on the railroads' 
joint RFA to their PTCSPs.

applicable docket number. The relevant PTC docket numbers for the host

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 PTCSP, a host 
railroad must submit, and obtain FRA's approval of, an RFA to its 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 25, 
2025, the following 21 host railroads jointly submitted an RFA to their 
respective PTCSPs for their Interoperable Electronic Train Management 
Systems (I-ETMS): Alaska Railroad; The Belt Railway Company of Chicago; 
BNSF Railway; Peninsula Corridor Joint Powers Board (Caltrain); 
Canadian National Railway; Canadian Pacific Railway; Central Florida 
Rail Corridor (SunRail); Consolidated Rail Corporation; CSX

Transit District; Northeast Illinois Regional Commuter Railroad 
Corporation (Metra); Northern Indiana Commuter Transportation District; 
South Florida Regional Transportation Authority; Southern California 
Regional Rail Authority (Metrolink); Terminal Railroad Association of 
St. Louis; and Union Pacific Railroad. This RFA covers an update to 
onboard software Version 6.5.5.0, which would require modifications to 
the ITC PTC Concept of Operations and to the HMI. The railroads' joint 
RFA is available in Docket Numbers FRA-2010-0028, -0029, -0039, -0042, 
-0043, -0045, -0048, -0049, -0051, -0054, -0056, -0057, -0058, -0059, -

    Interested parties are invited to comment on this RFA by submitting 
written comments or data. During FRA's review of these railroads' joint 
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 PTC systems. 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 these railroads' joint RFA to their PTCSPs at FRA's
