Crews are on the scene of a CP Rail freight train derailment in Ajax.

It happened near Westney and Taunton roads at around 9:30 a.m.

Reports from the scene suggest as many as a dozen freight cars have derailed from the tracks.

From an overpass just north of Taunton Road, the cars can be seen in a zig-zag pattern about 100 metres away.

Officials from CP say they are currently trying to organize a command centre in a nearby parking lot to get a clean-up plan in place. There have been no reports of any injuries.

The cargo the train was carrying has been contained to the cars and poses no danger.

Passersby who lived in the area said they were glad that the accident wasn’t worse.

“It’s a little frightening,” area resident Demetrios Stavros said.

“I was saying to my wife I was quite happy that these weren’t tankers carrying oil or some sort of petroleum product. It could have been much worse.”

It’s not clear how long it will take to clear the railway. The cause of the derailment has not been determined.

Metrolinx said GO Transit services have not impacted.
