GP15-1 113 at Tulsa, Oklahoma (date unknown).
This is the Mechanical Department’s service tracks area at Cherokee Yard. The locomotives are sitting on service track one, just southwest of the new metal diesel shop.
Above the cab of the subject locomotive is a silver tank and bucket elevator for bulk sand storage. Traction sand is pumped by air to the yellow locomotive loading gantry standing over the cab of GP38-2 437.
The view is looking northeast.
Special thanks to Mark Davidson.
