CN to update residents, media on Alberta derailment

CN, the Province of Alberta and Parkland County officials are speaking to the media at 10:30 a.m. MT to update when more than 100 people can return to their homes following an explosive train derailment west of Edmonton on the weekend.

Thirteen cars carrying oil and liquefied petroleum gas went off the rails near Gainford, about 80 kilometres west of Edmonton early Saturday.

Alberta's Minister of Environment and Sustainable Resource Development Diana McQueen, Parkland County Mayor Rod Shaigec and CN officials will speak at the briefing.

Two cars containing liquefied petroleum gas continue to burn after firefighters used explosives to punch more holes into ruptured rail cars at 6:45 p.m. Sunday in an effort to burn off the gas more quickly.

CN said the 134-car train was travelling to Vancouver from Edmonton at a normal speed of 35 kilometres an hour when it derailed.
