The Transportation Safety Board of Canada (TSB) is investigating after several rail cars tumbled into a southwest Calgary pond Monday morning following a CPKC freight train derailment.
Calgary police say the derailment happened around 7:30 a.m. near the interchange of Stoney Trail and Macleod Trail, just east of Sheriff King Street SW.
Images from the scene show at least half a dozen cars off the tracks, with several partially submerged in a large storm pond located next to the tracks.
CPKC confirmed that 13 cars derailed. The company says the train was carrying a mix of lumber, plywood, propane and argon.
There are no indications of leaks from any of the tanker cars, according to emergency officials.
CPKC says there were no injuries among the train crew.
Police and fire crews remain at the site, and additional CPKC teams are arriving to begin cleanup and recovery work.
“Anytime there’s a train derailment, depending on the products, we are always mindul of the hazardous releases,” says Calgary Fire Department spokesperson Alex Kwan. “So we do have a hazardous materials team from the fire department on scene, planning and doing modelling in case we identify the different products.”
The cause of the derailment is under investigation. Police have asked the public to stay away from the area while the investigation and cleanup continues.
Sheriff King Street SW is closed between Silverado Way and Silverado Boulevard SW for the investigation. Police say the road closures are expected to remain in effect for 36 hours.
