FORT SASKATCHEWAN — Canadian National Railway (TSX:CNR) is investigating what caused 15 cars to derail at a rail yard near a petroleum refinery north of Edmonton.
Thirteen empty cars left the tracks at the CN Rail yard near Shell Canada’s (TSX:SHC) Scotford refinery and tipped on to their sides.
Two other cars, which were hauling loads, stayed upright on the tracks and did not leak any material during the incident.
Kellie Svenson, a spokeswoman for the rail company, says the cars were moving at slow speeds and derailed while they were being switched around in the rail yard.
She says they’re still trying to determine how the incident occurred.
The refinery, about 40-kilometres north of Edmonton, can produce about 100,000 barrels of synthetic crude oil each day and also produces such things as gasoline, jet fuel, propane and diesel.
