Members of the Calgary Fire Department, Calgary Police Service and rail officials are on the scene of a train derailment near the intersection of 15 St. and Blackfoot Trail S.E.

According to the CPS Duty Inspector Leah Barber, at around 5:00 p.m. Wednesday, several tanker cars left the rail, before coming to a rest on their side in the Alyth industrial area.

CPS members are door knocking in the community of Inglewood, asking residents to evacuate the area.

Duty Inspector Barber says there have been reports of a hissing noise emanating from the cars.

CP Rail official Ed Greenberg say the derailment occurred while a northbound train was leaving the Alyth Yard at 4:55 p.m. As many as eight cars left the track.

The tankers contained diluents, a diluting agent used in oil pipeline applications.

The cause of the derailment is under investigation.
