The ready tracks at the Union Pacific M-19A Diesel Shop. Chicago Illinois. June 2007., a photo by Eddie from Chicago on Flickr.
I took this photo back in June of 2007.
Looking north alongside West Kinzie Street west of North Pulaski Road, We see newer model diesel electric freight locomotives at the Union Pacific Railroad's M-19A Diesel Shop.
This is a former Chicago & NorthWestern Railroad facility acquired through merger.
