The loaded 124-car train derailed in Bridgeport early Sunday morning. The clean-up continued Monday morning.
BNSF spokesman Andy Williams says 15 of the cars derailed and blocked the Highway 88 crossing on Main Street in Bridgeport.
Bridgeport Police Chief Scott Decoste says crews worked all day Sunday and into the night to clean up the mess, but he predicted the crossing would continue to be blocked most of Monday morning.
BNSF says the track was damaged in the derailment and will have to be repaired.
Officials are still working to determine the cause of the derailment.
