Investigators travel Thursday evening from Edmonton to a railway near Field, B.C. after 27 cars have derailed.
Transport Security Council spokesperson Alexandre Fournier said the derailment took place around 10:10 am on Thursday, on the Canadian Pacific Laggan railway line, which goes from Calgary to Field, BC to the upper spiral tunnel of the Yoho National Park.
Fournier could not confirm whether there had been any spills, which were the vehicles or if there had been an environmental impact.
