KIMBALL, S.D. (AP) — A freight train derailment in Brule County is being blamed on a problem with the tracks.

Dakota Southern Railway spokesman Mark Cutright tells The Daily Republic (http://bit.ly/2uLMaJt ) that the wreck on Saturday about 6 miles east of Kimball was caused by a kink or buckle in the tracks. He says it's not unusual.

Fourteen cars on the grain train went off the tracks. No one was hurt. Cleanup is continuing.
