A Canadian National Railway Co. train derailed about 180 kilometers (111 miles) west of Alberta’s capital Edmonton today.
Thirteen cars on a train traveling eastbound derailed around 1 a.m. local time, including 12 loaded with lumber and one carrying sulfur dioxide, which is considered a dangerous good, Patrick Waldron, a CN Rail spokesman, said in an e-mailed statement.
There were no injuries or environmental concerns because the car carrying sulfur dioxide is upright and not leaking, Waldron said. CN Rail crews are on site and the cause of the derailment is being investigated, he said.
The incident follows the explosion of CN Rail cars last month near Gainford, Alberta, after 13 cars carrying oil and propane derailed and led to the evacuation of the community for more than two days. Regulators are scrutinizing the transport of crude by rail in Canada and the U.S. after a train carrying oil jumped the tracks and exploded in Lac-Megantic, Quebec, in July.
