Union Pacific Railroad track maintenance equipment. Des Plaines Illinois. May 2012., a photo by Eddie from Chicago on Flickr.
I took this photograph after work one evening last year around sunset.
The Union Pacific Railroad had these important pieces of self propelled track maintenance equipment parked just north of Dempster Street, west of Wolf Road, in northwest suburban Des Plaines Illinois.
This equipment was being staged along the former Chicago & NorthWestern Railroad's freight only cut off line.
