This document provides the public with notice that, on September 20, 2024, the Massachusetts Bay Transportation Authority (MBTA) submitted a request for amendment (RFA) to its FRA-certified positive train control (PTC) system to establish a Construction Zone (CZ) during November and December 2024, in order to install Automatic Train Control (ATC) on the final segment of MBTA's Fitchburg Line between CPF-330 and CPF-335. 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 MBTA's RFA to its PTC system.
This is a notice published in the Federal Register by Transportation Department, Federal Railroad Administration. Notices communicate information, guidance, or policy interpretations but may not create new binding obligations.
This document is classified as a notice. It may or may not create enforceable regulatory obligations depending on its specific content.
Notice of availability and request for comments.
FRA will consider comments received by October 22, 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.
