Eastbound Union Pacific unit coal train entering the city of Chicago at sunset. Chicago Illinois USA. October 2006.

I took this photo one evening after work, in October of 2006. An eastbound Union Pacific Railroad unit coal train has just recieved a green block signal with clearance from the dispatcher, and is now slowly passing the railroad crossing on North Kilbourn Avenue and West Kinzie Street.The late day Autum sun is setting in the western skies, as the train travels eastbound over the former Chicago & Northwestern Railroad mainline.
