BNSF cleaning up after coal train derailment near Bismarck

BISMARCK -- BNSF Railway is cleaning up after a coal train derailment east of Bismarck.

Thirty-one-cars went off the track Saturday afternoon, and 29 of them tipped on their sides. No one was hurt. The wreck sparked a small grass fire.

Railroad spokeswoman Amy McBeth says the cause of the derailment wasn't immediately known.

The tracks were closed, with other trains being rerouted or delayed.
