South Wye Junction near Chicago Union Station. November 1983.

I took this photo just south of Chicago Union Station, in November of 1983. This is a behind the scenes look at Chicago's very busy Amtrak terminal and switching operations. South Wye Junction is located near where the old Union Street interlocking tower was located. Here, Amtrak trains are taken to the coachyard, serviced, and turned around in preparation for another upcoming departure from Chicago Union Station.
