A freight train hauling coal derailed on Union Pacific tracks near Willow Road and Shermer Avenue this afternoon by the Northbrook-Glenview border.



Witnesses said the bridge overpass over Shermer Avenue collapsed in the accident.



Union Pacific Spokesman Mark Davis said the train derailment occurred at 1:45 p.m. as the train was enroute to a utility plant in Wisconsin from a coal mine in eastern Wyoming.



The train had three locomotive engines and 31 of its 138 train cars derailed, Davis said. About a third of the train had passed the 86-foot-long bridge before the derailment and the locomotives did not derail. There were no reported injuries from the derailment, said Davis.



He said a small fire occurred after the incident that involved vegetation in the area. He said the tracks being used are only used by its freight lines. No Metra service occurs on these tracks, said Davis.
