Jan. 23: Fatigue a Factor in Train Collision
The TSB released its investigation report into the Jan. 2012 collision between a CN freight train and a maintenance vehicle in BC. There were no injuries and no derailment, although the maintenance vehicle was destroyed. The TSB found that the maintenance foreman had taken the south track instead of the north to reach a malfunctioning signal. It noted that his diminished alertness likely contributed to this decision. He’d had trouble sleeping due to a cold and had been called into work to fix the signal at 2:30 am, a “circadian low period” when people can experience reduced alertness.
