NORTHBROOK, Ill. -- A Union Pacific spokesman says a freight train derailed and a bridge over a stretch of road has collapsed in the northern Chicago suburbs.

Mark Davis says four cars of a 138-car freight train derailed about 1:45 p.m. local time Wednesday. He says the three-engine train was carrying coal from an eastern Wyoming mine to a utility in Wisconsin.

Glenview police responded to the scene near the borders of Glenview and Northbrook but did not immediately provide any information.

Davis says no injuries were reported. He says some dry vegetation in the area caught fire.

Davis says the incident happened on a rail line not used by Chicago commuter services.

Union Pacific is investigating the cause of the derailment.
