On 14 February 2015, a Canadian National  crude oil unit train hauling 100 tank cars, 68 loaded with Petroleum Crude Oil and 32 loaded with Petroleum Distillates  derailed and the crew observed a fire about 10 cars behind the locomotives. The temperature at the time was -31°C.  During the derailment, a number of cars were breached, released product, and ignited a large fire that initially involved 7 of the derailed cars. Additional product was subsequently released, and a total of 21 cars sustained fire damage ranging from minor to severe.
