[Docket Number FRA-2010-0044]

Trinity Railway Express'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 October 
30, 2024, Trinity Railway Express (TRE) submitted its Positive Train 
Control Safety Plan (PTCSP), Version 2.0, dated October 30, 2024, to 
FRA's Secure Information Repository. TRE asks FRA to approve its 
updated PTCSP and certify TRE's Interoperable Electronic Train 
Management System (I-ETMS) as a ``mixed'' positive train control (PTC) 
system. 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 TRE's RFA to its 
PTCSP.

DATES: FRA will consider comments received by February 10, 2025 before 
taking final action on the PTCSP. 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 
railroad is Docket No. FRA-2010-0044. 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.

FOR FURTHER INFORMATION CONTACT: Gabe Neal, Staff Director, Signal, 
Train Control, and Crossings Division, telephone: 816-516-7168, email: 
[email protected].

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 October 
30, 2024, TRE submitted an RFA to its PTCSP for its I-ETMS PTC system 
which seeks FRA's approval to change the classification of its PTC 
system to a Mixed PTC system. In its PTCSP, TRE asserts that the I-ETMS 
PTC system it is implementing is a mixed PTC system as defined in title 
49 Code of Federal Regulations (CFR) 236.1015(e). The PTCSP describes 
TRE's I-ETMS implementation and the associated I-ETMS safety processes, 
safety analyses, and test, validation, and verification processes used 
during the development of I-ETMS. The PTCSP also contains TRE's 
operational and support requirements and procedures. That RFA is 
available in Docket No. FRA-2010-0044.
    Interested parties are invited to comment on TRE's RFA to its PTCSP 
by submitting written comments or data. During FRA's review of TRE'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). 
However, FRA may elect not to respond to any particular comment, and 
under 49 CFR 236.1009(d)(3), FRA maintains the authority to approve or 
disapprove the PTCSP at its sole discretion.

Privacy Act Notice
