Fraser's son, Dylan Paradis, was a conductor on the Canadian Pacific freight train that plummeted off a bridge in February 2019. Paradis, engineer Andrew Dockrell and trainee Daniel Waldenberger-Bulmerone were in the lead locomotive and were killed.
Fraser and Dockrell's family have filed lawsuits alleging negligence in the derailment that sent 99 cars and two locomotives tumbling off the tracks.
"Gross negligence is a good word. I think it's an utter lack of respect for human life," Fraser said.
The westbound train was parked on a grade and had its air brakes on when it started rolling on its own, gaining speeds far above the limit for the mountain pass near Field, B.C.
