Union Pacific crews cleaned up a derailment at its north Omaha rail yard Friday morning.
Railroad spokesman Mark Davis said two locomotives and four cars derailed near 11th and Clark, about four blocks north of TD Ameritrade Park, about 9 a.m. He said three of the cars were hoppers, possibly carrying grain, and the fourth was empty.
There was minor track damage as a result of the derailment and crews were working to get the train back on the tracks. The cause of the derailment is under investigation.
