GP38-2s 694 and 693 at Oklahoma City, Oklahoma (date unknown).
The train is eastbound, having just crossed the bridge over the North Canadian River. The train is just entering the Frisco’s Oklahoma City Yard. This photo was taken from the South Lincoln Boulevard Bridge. In the distance above and to the right (north) over the train is the Producer’s Co-Op Cotton Seed Oil Mill.
Close to the rear of the train is the Santa Fe’s north/south main crossing over the Frisco. West of that underpass the train has just passed the joint Frisco and Rock Island Oklahoma City Station.
Special thanks to Mark Davidson.
