Residents evacuated after a train derailed in the northeast Iowa town of Jesup Sunday have been let back in their homes. The freight train de-railed near downtown Jesup late Sunday afternoon.

Three of the cars carrying ethanol jumped the Canadian National Railway tracks, while several other cars started to tip. One of the cars developed a small leak, but it was repaired after railroad officials arrived on the scene overnight. About one dozen nearby homes were evacuated as a precaution. Rail crews have since righted the cars and cleaned up the area.

Residents were allowed back in their homes by mid-morning. No one was injured. The cause of the de-railment has not been determined, however officials are looking at the possibility that heavy rains could have washed out a portion of the track.
