This document provides the public with notice that, during March, April, and early May of 2021, nineteen host railroads submitted requests for amendments (RFA) to their FRA-approved Positive Train Control Safety Plans (PTCSP). As these RFAs 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' RFAs to their PTCSPs.
