TSB says supervisor error caused CP Rail crash in Cache Creek, prompting new safety measures across B.C.

The Transportation Safety Board of Canada (TSB) says a supervisor’s error led to a freight train collision with a maintenance vehicle on a Canadian Pacific Railway (CP Rail) line in Cache Creek, highlighting the need for stronger safety procedures on B.C.’s rail network.

According to the TSB’s investigation, the incident occurred on December 29, 2022, when a CP Rail supervisor was inspecting the main tracks in a road–rail vehicle — a truck that can operate both on rail lines and regular roads. While repairing a detected track defect, the supervisor mistakenly cancelled the wrong track occupancy permit, leaving the section he was working on unprotected.

Moments later, an eastbound freight train struck the unoccupied maintenance vehicle. Fortunately, no injuries were reported, though the collision caused property damage and prompted an internal review by CP Rail.

The TSB says it issued a safety advisory to the company, noting that the process for cancelling electronic track permits was “less rigorous” than traditional radio-based verification systems. Following the report, CP Rail has confirmed it has implemented new safety measures, including upgrades to its electronic permit application and additional staff training.

Rail safety remains a concern across British Columbia, particularly in communities such as Kamloops, Chilliwack, and Surrey, where CP and CN Rail operate major freight corridors through residential areas. Transportation experts say the Cache Creek incident underscores the need for consistent communication protocols and stronger safety oversight to prevent similar errors.
