Notice of availability and request for comments.
Summary
This document provides the public with notice that, on November 14, 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 November 7, 2024, to support updates to Amtrak's Onboard Computer (OBC) Serial platform and Fusion software release. 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.
