The Plug Between Runs
Here we see GM&O’s Chicago commuter train which was known as “the Plug.” It's being serviced on a very cold day at Glenn Yard located south of Chicago. The commuter train ran between Chicago Union Station and Joliet on the GM&O, former Alton; Metra now calls this line the Heritage Corridor. I've posted shots from this servicing here before, but not this particular image.
