(Bloomberg) -- A Canadian National Railway Co. train carryingcrude oil derailed and caught fire in a remote area of northernOntario, blocking rail traffic between Toronto and Winnipeg,Manitoba.

Canadian National said on its website and in a later statementthat the train derailed around 2:45 a.m. Saturday near Gogama,about 600 kilometers (373 miles) north of Toronto. The train’s crewreported a fire, though no injuries, spokeswoman Emily Hamer saidin an e-mail. The company hasn’t yet determined the exact number ofcars that derailed or how many are involved in the fire.

“CN crews are responding to the site in order to undertake thenecessary repairs,” the Montreal-based company said on its website.“Both westbound and eastbound traffic scheduled to cross theaffected area is currently obstructed, and may be delayed by 24hours or more.”

The company said in the statement that a bridge over a waterwaywas damaged in the derailment and five tank cars ended up in thewater, some of them on fire. The cars, carrying crude oil fromAlberta, are CPC-1232 models that began to be introduced in theindustry in 2011 to increase safety. Emergency responders havedeployed two lines of boom in the water to contain the oil.

CN also dispatched Chief Operating Officer Jim Vena to the site.In the statement, he issued an apology to residents of the area fordisruptions caused by the crash.

Via Rail Canada said in a statement that because of the CNderailment, it canceled its Saturday night passenger train fromToronto to Vancouver and would terminate an eastbound train on thesame route when it reaches Winnipeg.

Second Accident

The accident marks the second derailment of a Canadian Nationaloil train in three weeks in northern Ontario. A train with 100cars, all carrying crude from the oil-producing region of Albertato eastern Canada, derailed on Feb. 14 about 30 miles north ofGogama. A total of 29 cars were involved in that incident and sevencaught fire, a spokesman said at the time.

About 18 freight trains a day use the line, which links westernand eastern Canada. Canadian oil producers have grown dependent onshipping crude by rail as pipeline capacity has becomeconstrained.

Investigators from the Transportation Safety Board of Canadahave been sent to the site, which is 37 kilometers from theprevious accident, the government agency said in a statement. Thetrain was headed to Levis, Quebec, and 30 to 40 rail cars derailed,agency spokesman John Cottreau said by phone.
