The company said the line was cleared and that shipments would resume, although customers could still face some delays as traffic returns to normal.

13 cars on a mixed-freight train derailed near the hamlet of Gainford, Alberta. One car containing highly flammable propane exploded and three others burst into flames.

There were no injuries, but the incident again focused attention on the safety of shipping hazardous goods by rail, coming just a few months after 47 people died when a crude oil train derailed and exploded in Lac-Megantic, Quebec.

The line carries traffic between the province of Alberta’s capital, Edmonton, and the Pacific ports of Vancouver and Prince Rupert, British Columbia. (Reuters)
