I took this picture back in November of 1989.
Seen here is a northbound Norfolk Southern freight train, that for some unexplained reason, has a Southern Pacific bay window caboose on the trains rear. Just ahead of the caboose is a pre 1970 Great Northern Railroad boxcar in the 1967 Big Sky Blue color scheme. On March 2nd 1970, the Great Northern -Northern Pacific -The Chicago, Burlington & Quincy -and the Spokane, Portland & Seatle railroads merged and became the Burlington Northern Railroad. The train is crossing the Chicago Sanitary and Ship Canal at approximately west 41st Street.
