U30B 836 at Oklahoma City, Oklahoma (date unknown).
The locomotive is sitting in the mechanical department’s service tracks area. In the background to the northeast (left) are the elevator and bulk storage silo for locomotive sand and the diesel shop. Parked alongside is a remote service truck with fuel and sand to resupply locomotives away from the terminal.
In the far distance to the right of the locomotive are the 3 circus style loading and unloading ramps for trailers on flatcars (TOFC) service. Just north of this area, near the northeast end of the yard is the locomotive turntable.
The view is looking east northeast.
Special thanks to Mark Davidson.
