Gatineau Quebec - In its investigation R13E0069 release today, the Transportation Safety Board of Canada (TSB) found that limited capacity of the drainage system beside the tracks led to the saturation of the track bed and created a void under the tracks.
 
As the heavily loaded train crossed that section of the tracks, the weakened track structure failed resulting in a derailment.
 
On 28 Apr 2013, at 3:55 Central Standard Time, a Canadian Pacific Railway freight train, proceeding westward from Wilkie, Saskatchewan to Hardisty, Alberta, derailed seventeen cars loaded with potash at Mile 80.7 on the Hardisty Subdivision, near Provost, Alberta.
 
Approximately 350 feet of track was destroyed.
 
There were no injuries.
