PLUMMER — Residents in a small town in northwestern Minnesota are returning home after a two-hour evacuation prompted by a nearby rail-car derailment.

Canadian Pacific said a semi-trailer truck collided with a train near Plummer on Saturday morning. Railroad spokesman Ed Greenberg said at least one rail car left the track.

No members of the train crew were injured. The truck driver’s condition hasn’t been released.

The rail car held bunker oil, a fuel oil used aboard ships. Greenberg said some oil leaked, and that an environmental team is on the scene.

Residents living in a one-mile radius of the crash site were evacuated about 8 a.m. as a precaution. The evacuation order was lifted about two hours later.

Plummer is southeast of Thief River Falls.
