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 March 23, 2023, the Massachusetts Bay Transportation Authority (MBTA) submitted a request for amendment (RFA) to its FRA-certified positive train control (PTC) system in order to support the reconfiguration of its underlying Automatic Train Control (ATC) system on its commuter rail network. On MBTA's South Side, the ATC System in the area is being reconfigured requiring the PTC system to be taken out of service during the reconfiguration as well as during the recommissioning of the ATC system and MBTA's Advanced Civil Speed Enforcement System II (ACSES II). FRA is publishing this notice and inviting public comment on MBTA's RFA to its PTC system.

DATES:

FRA will consider comments received by May 1, 2023. 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-2010-0030. 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 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 or discontinuance of a signal and train control system. Accordingly, this notice informs the public that, on December 21, 2022, MBTA submitted an RFA to its ACSES II system, which seeks FRA's approval to temporarily discontinue its PTC system to install Construction Zone (CZ) Transponders on MBTA's Middleboro Main Line segment between May and June 2023. That RFA is available in Docket No. FRA-2010-0030.

Interested parties are invited to comment on MBTA's RFA to its PTC system 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. 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 PTC system at FRA's sole discretion.
