Authorities have evacuated a small town in northwestern Minnesota after a freight train collided with a propane truck that caught fire.

Sgt. Jesse Grabow with the Minnesota State Patrol says the crash happened around 12:25 p.m. Thursday in Callaway.

Grabow says crews are trying to put out the burning tanker. He says the town of about 230 was evacuated as a precaution.

Canadian Pacific says the crash derailed seven empty cars and the locomotive on the 82-car train. Railroad spokesman Andy Cummings says two crew members were hurt and were offered medical services.

Becker County Sheriff Todd Glander says it's believed their injuries are minor.

Canadian Pacific says it will investigate how the vehicle came to be on the tracks.

Callaway is about 50 miles east of Fargo, North Dakota.
