No one was hurt when a freight train derailed in Taber. (CBC)More than a dozen cars have jumped the tracks in the town of Taber, southeast of Calgary.

Fourteen hopper cars of a Canadian Pacific Rail freight train overturned at about 2:30 a.m. on Tuesday. No one was hurt in the derailment and nothing hazardous or toxic leaked.

An evacuation wasn't necessary, but traffic in the town of Taber will likely be disrupted for the rest of the day, said Brad Mason, head of emergency services.

"We would have been prepared to conduct evacuations and rescues as required, but thankfully we didn't need to," he said. "Certainly our risk analysis indicates that is one of the most likely events."

Canadian Pacific crews are in the process of cleaning up.
