This document provides the public with notice that, on July 20, 2023, the Long Island Rail Road (LIRR) submitted a request for amendment (RFA) to its FRA-certified positive train control (PTC) system in order to establish an Advanced Civil Speed Enforcement System II (ACSES II) Construction Zone (CZ) to support the construction of an extension of the Patchogue Siding and associated signal system changes for LIRR's modification of the current track infrastructure. FRA is publishing this notice and inviting public comment on the railroad's RFA to its PTC system.
Amtrak's Request To Amend Its Positive Train Control Safety Plan and Positive Train Control System
This document provides the public with notice that, on July 14, 2023, the National Railroad Passenger Corporation (Amtrak) submitted two requests for amendment (RFA). The first RFA is to Amtrak's FRA-approved Positive Train Control Safety Plan (PTCSP) and its Advanced Civil Speed Enforcement System II (ACSES II), which seeks FRA's approval to introduce modified safety server software to address a known defect and updates to type approval documentation. The second RFA is to Amtrak's FRA-certified positive train control (PTC) system for its ACSES II system, which seeks FRA's approval to install Construction Zone (CZ) transponders to support cutover activities on the Philadelphia to Washington (PW) line. As these RFAs may involve requests for FRA's approval of proposed material modifications to an FRA-certified PTC system, FRA is publishing this notice and inviting public comment on Amtrak's RFAs to its PTCSP and PTC system.
