CN Rail train derails west of Edmonton

A CN Rail train carrying liquefied petroleum gas and crude oil has derailed west of Edmonton, prompting a voluntary evacuation of an unknown number of homes in the area.

Parkland County Emergency Services says it received a call about the accident involving a westbound train around 1 a.m. MT Saturday.

Thirteen cars left the tracks along Highway 16 and Range Road 61 near the hamlet of Gainford.

Carson Mills, spokesman for Parkland County, told CBC News that two of the cars containing liquefied petroleum gas are on fire.

Highway 16 traffic has been re-routed north along Secondary Highway 765, westbound along Secondary Highway 633 and returning southbound on Secondary Highway 757.
