Notice of availability and request for comments.
Summary
This document provides the public with notice that on July 11, 2024, five host railroads submitted a joint request for amendment (RFA) to their FRA-approved Positive Train Control Safety Plans (PTCSP). As this joint RFA may involve requests for FRA's approval of proposed material modifications to FRA-certified positive train control (PTC) systems, FRA is publishing this notice and inviting public comment on railroads' joint RFA to their PTCSPs.
