GP38-2s 686 and 667 lead a train at Oklahoma City, Oklahoma on November 13, 1973.
In the background you can see Union Station and to the right of the train is the Rock Island main line. The photographer appears to be on the ATSF right-of-way.
Incidentally, this scrapyard shipped a lot of cars of scrap on the Frisco. This scene has changed today with the new I-40 now located between the scrapyard (which is gone) and the RI (now UP) main line.
Special thanks to Jerome Lutzenberger.
