Caboose 1163 at Enid, Oklahoma (date unknown).
The photograph is looking east/northeast. The train is eastbound and has just passed North Jefferson Street. The caboose is in front of the W.B. Johnson Elevator A.
The white concrete portion of the elevator is washed out in the image and blends into the sky. However, very distinguishable are the double doors on the concrete portion at its southwest corner and the frame elevator immediately to its west. Also in this view, one can also see the wood frame loading dock on the south side of the track.
Special thanks to Mark Davidson.
