CASSELTON, N.D. - Authorities are evacuating part of a North Dakota town near the scene of a fiery oil train derailment.
Cass County Sheriff's Sgt. Tara Morris says as many as 300 residents of Casselton may be evacuated.
Morris says there's no immediate danger. It's a precaution in case winds change as some derailed cars continue to burn.
Morris estimates about 10 cars from a mile-long train caught fire and will have to burn out. She said it could take up to 12 hours before authorities can get close.
The derailment Monday afternoon happened about a mile outside of Casselton. The town of 2,400 people is about 25 miles west of Fargo.
Officials are still investigating what caused the derailment, but a second train carrying grain was somehow involved.
