DEPARTMENT OF TRANSPORTATION

[Docket Number FRA-2010-0030]


Massachusetts Bay Transportation Authority's Request To Amend Its 
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 
11, 2024, the Massachusetts Bay Transportation Authority (MBTA) 
submitted a request for amendment (RFA) to its FRA-approved Positive 
Train Control Safety Plan (PTCSP) to install Construction Zone (CZ) 
Transponders to reconfigure its positive train control (PTC) system on 
the South Side Middleboro Main Line (MML) at the Pilgrim Interlocking 
at Milepost (MP) 34.86 to its final configuration in order to interface 
with the adjacent new South Coast Rail (SCR) Lines. The CZ will result 
in the suspension of portions of the PTC system on the MML from 
December 1, 2024, to December 15, 2024. As this RFA involves 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 MBTA's RFA to its PTC system.

DATES: FRA will consider comments received by November 13, 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.

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, October 11, 
2024, MBTA submitted an RFA to its PTCSP for its Advanced Civil Speed 
Enforcement System II (ACSES II), which seeks FRA's approval to install 
a CZ to reconfigure its PTC system on the MML at the Pilgrim 
Interlocking at MP 34.86 to its final configuration in order to 
interface with the adjacent new SCR Lines. The CZ will result in the 
suspension of portions of the PTC system on the MML from December 1, 
2024, to December 15, 2024. That RFA is available in Docket No. FRA-
2010-0030.
    Interested parties are invited to comment on MBTA's RFA by 
submitting written comments or data. During FRA's review of MBTA'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). 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.

Privacy Act Notice
