A small town in northwestern Minnesota was evacuated Thursday afternoon after a Canadian Pacific freight train collided with a propane truck that caught fire.

Minnesota State Patrol Sgt. Jesse Grabow told the Associated Press that the town of Callaway, population 230, was evacuated as a precaution. The evacuation was to remain in effect until at least noon Friday.

Canadian Pacific said seven empty train cars and one locomotive derailed at about 12:25 p.m. local time Thursday. None of the cars were carrying hazardous materials and none of the train cars caught on fire. Two members of the train crew sustained non-life-threatening injuries and were both taken to a hospital in Detroit Lakes.

The state Department of Public Safety says the propane is being vented and burned off. WDAY-TV reported that the tanker contained 10,000 gallons of propane. 

Fire crews from 15 departments worked to contain the fire. WDAY-TV reported that a large explosion shook the ground in Callaway at approximately 10:30 p.m. local time Thursday.
