Federal Railroad Administration December 3, 2024 – Federal Register Recent Federal Regulation Documents

This document provides the public with notice that, on November 21, 2024, the National Railroad Passenger Corporation (Amtrak) submitted a request for amendment (RFA) to its FRA-approved Positive Train Control Safety Plan (PTCSP) to provide supplemental information to its initial RFA, submitted October 16, 2024, which requested FRA's approval for an increase to the system maximum operational speed from 150 miles per hour (MPH) to 160 MPH. As this RFA may involve a request for FRA's approval of proposed material modifications to an FRA- certified positive train control (PTC) system, FRA is publishing this notice and inviting public comment on Amtrak's RFA to its PTCSP.
