SUMMARY:

This document provides the public with notice that, on July 1, 2024, the National Railroad Passenger Corporation (Amtrak) submitted a request for amendment (RFA) to its FRA-approved Positive Train Control Safety Plan (PTCSP) to request approval for a planned positive train control (PTC) system outage of its Mixed System PTC system for maintenance purposes during the month of August 2024. As this RFA may involve a request for FRA's approval of proposed material modifications to an FRA-certified positive train control (PTC) system, FRA is publishing this notice and inviting public comment on Amtrak's RFA to its PTCSP.

DATES:

FRA will consider comments received by July 31, 2024. 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 host railroad is Docket No. FRA-2010-0029. 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.

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 1, 2024, Amtrak submitted an RFA to its PTCSP for its Mixed System PTC system, which is comprised of the Interoperable Electronic Train Management System (I-ETMS), seeking FRA's approval for a temporary outage of the system to perform an update to the Back Office Server (BOS) in August 2024. That RFA is available in Docket No. FRA-2010-0029.

Interested parties are invited to comment on Amtrak's RFA to its PTCSP by submitting written comments or data. During FRA's review of Amtrak'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. See49 CFR 236.1021; see also49 CFR 236.1011(e). Under 49 CFR 236.1021, FRA maintains the authority to approve, approve with conditions, or deny a railroad's RFA to its PTCSP at FRA's sole discretion.
