Historic Photo! New York Central Railroad EMD model SW-1 yard switcher locomotive #580 in Chicago Illinois, circa 1950's. From the internet.

I spotted this rare historic color 1950's era photo from My own hometown recently on the internet.

New York Central Railroad EMD SW-1 yard switcher #580, is viewed running M.U'd with another locomotive. I believe this was photographed near the now demolished site of South union Tower near Chicago Union Station during the early to mid 1950's.

If anyone can identify the exact location, I would really appreciate it.

Thanks.
