FARGO, N.D. (AP) — Public officials and others are angry about a second train derailment within a year near the southeastern North Dakota town of Casselton.

BNSF Railway officials say it appears that 21 cars of an eastbound train carrying lumber and paper products derailed shortly after 5:30 p.m. Thursday about 2 miles west of Casselton. The wreckage was then struck by a westbound train carrying empty oil tankers. Twelve cars on that train derailed.

No injuries were reported.

The accident comes less than a year after a derailment involving oil tankers 1 mile west of Casselton sparked massive explosions.

Cass County Sheriff Paul Laney says the latest accident raises serious issues about rail safety.

BNSF spokeswoman Amy McBeth says the railway is "fully investigating" the incident and are talking with public officials.
