About 43 westbound Canadian Pacific (CP) Rail cars carrying potash derailed northeast of Fort Macleod, Alta., Sunday morning, RCMP say.

At 8:15 a.m., Mounties responded to a train derailment between Range Roads 251 and 252, near Highway 3. Fire crews and CP Rail also came to the scene, according to police.

There are no injuries or concerns to public safety, RCMP say.

CP crews have started recovery work, a spokesperson for CP Rail told CBC News in an email.

The cause of the derailment is under investigation, they added.

RCMP said traffic in the area is being re-routed. Westbound Highway 3 traffic is being diverted onto the shoulder of the road for the next several hours as crews work at the scene.
