Canadian Pacific Railway's Request To Amend Its Positive Train Control System

Federal Railroad Administration (FRA), Department of Transportation (DOT).

Notice of availability and request for comments.

This document provides the public with notice that, on March 27, 2025, Canadian Pacific Railway (CP) submitted a request for amendment (RFA) to its FRA-certified positive train control (PTC) system to temporarily disable the system for a period not to exceed three hours in order to increase the capacity of its PTC system in preparation for consolidation. As this RFA may involve 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 CP's RFA to its PTC system.

FRA will consider comments received by May 5, 2025. FRA may consider comments received after that date to the extent practicable and without delaying implementation of valuable or necessary modifications to a PTC system.
