New Jersey Transit's Request To Amend Its Positive Train Control Safety Plan and Positive Train Control System

This document provides the public with notice that, on June 22, 2026, New Jersey Transit (NJT) submitted a request for amendment (RFA) to its FRA-approved Positive Train Control Safety Plan (PTCSP), seeking approval to update its Advanced Civil Speed Enforcement System II (ACSES) positive train control (PTC) system's main onboard software with a new software release, known as Back-to-Back (also referred to as B2B or Rev 7). 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 NJT's RFA to its PTCSP.
