Employee fatigue and inadequate train handling are to blame for 13 rail cars going off the tracks in Calgary.
The Transportation Safety Board released its report into the February 2016 derailment at the Alyth Yard in the southeast.
It says the crew member was likely fatigued because of two weeks of poor sleep and going without rest for 23 hours leading up to the accident.
Also, the CP freight train was moving too fast during a switching operation, which overstretched the train as it was travelling through a curve.
The cars derailed when several wheels came off the rail, but no one was injured and dangerous goods didn’t spill onto the yard.
However, the derailment did cause road closures in Inglewood and cut power for hundreds of people in the area.
The report says fatigue is a major safety risk and CP hasn’t taken enough action to address the issues.
CP emailed statement to 660 NEWS in response: “CP is a strong advocate for a scheduling system where all locomotive conductors and engineers would have scheduled time off, predictable work patterns and as a result, a more consistent work/life balance. We are working closely with our stakeholders, including the union leadership, on this important issue.”
