CALGARY, Oct 19 (Reuters) - A train carrying crude oil and liquefied petroleum gas derailed west of Edmonton, Alberta, on Saturday, causing an explosion and fire but no injuries, Canadian National Railway said on Saturday.
One rail car carrying liquefied petroleum gas on the westbound train exploded and three others also caught fire. Emergency crews battled the flames and worked to prevent the burning cars from triggering more explosions, a municipal authority spokesman said.
Residents were evacuated from Gainford, Alberta, 85 km (53 miles) from the provincial capital Edmonton, after the accident, which highlighted concerns in Canada about moving oil by rail. The community, part of the municipality of Parkland County, has a population of just over 100 people.
"We have cars on fire right now and there was an explosion earlier this morning. The major priority right now for our guys out in the field is containing these fires," said Parkland County spokesman Carson Mills.
