TSB says brake failure, cold weather led to deadly train derailment near Field, B.C.

CALGARY — An investigation into a fatal train derailment near the British Columbia-Alberta boundary has found the locomotive’s brakes failed with prolonged exposure to cold temperatures.

The Transportation Safety Board of Canada has released its findings into the February 2019 derailment that killed three Canadian Pacific Railway employees.

The train was parked on a grade near Field, B.C., when it started rolling on its own, gaining speed, and 99 grain cars and two locomotives plummeted off a bridge.
