|AT&SF GP40X 3808 at Roosevelt Road and Michigan Avenue, Chicago, Illinois, September 1979, photo by Chuck Zeiler. Number 3808 was built in May 1978 (c/n 776054-7) and became BNSF 3038 on May 15, 1998. It is seen here as part of EMD's trade show exhibit on the site of the Illinois Central's Central Station, which had been demolished in 1974. At the time of this photo, I was employed by a company with offices on the 52nd floor of the Standard Oil Building (later, the Amoco Building, after they became aware of the acronym of the original name), which is the tall white building behind the 50 Series banner. I looked out my office window and noticed a lot of activity where normally there was just empty tracks. I decided to check it out on my lunch hour. As it happened, I was dressed in a business suit so no one questioned my presence without credentials.
