The Transportation Safety Board has released details on the derailment of a Canadian Pacific train in September.
The derailment, which occurred just west of Blucher, was carrying potash to Saskatoon when it derailed due to cracks in a rail joint.
A report shows the cracks made the rail joint weak, and it crumbled under the weight of the train.
In total, 37 cars derailed in the incident, with around 760 metres of track damaged.
No dangerous goods were involved and no one was hurt in the incident.
