Location is Oklahoma City, Oklahoma.
The photograph was taken southeast of the central downtown business core at East Yard, MP 539.5. The locomotives are on the service tracks west of the Oklahoma City 1-track diesel shop. The mechanical facilities are on the north side of the yard, near its west end. The car department operated a 2-track covered work shed with open lower sides repair in place (RIP) facility to the northeast of the diesel shop.
Additional unidentified number locomotives in the consist include another GP7 phase I (SLSF 500-524) and a GP38-2 phase Ib2 (SLSF 683-689). Due to the size of the fuel tank we can further narrow the other GP7 to one that was originally equipped with a steam boiler (SLSF 500-514). Built by General Motors (GM) Electro-Motive Division (EMD), the units were among 101 of 128 Frisco GP7 locomotives (78.9%) built at their Plant Number 3 in Cleveland, Ohio.
On the far left is the South Byers Avenue overpass over the west end of the yard, and further north the North Canadian River. Today, after roadway improvements and construction of a new replacement bridge the overpass roadway has been renamed South Lincoln Boulevard. An American flag is flying in front of the yard office above the cab of the far end locomotive.
Hanging above the rear truck of the closest locomotive is a McCarty rerail frog. In use the rerail frogs straddle two ties and hook over the rail head. The carry handles at each end serve as hanger attachment points and double as tie side clamps to keep the device from sliding as wheels climb the inclined ramp. There are inside and outside designs that are used in pairs for rerailing equipment.
Other interesting details in the image include the Jenga style stacked brake shoes near the pilot of SLSF 646, the 55-gallon drums of lube oil and the adjacent concrete multiprong foundations.
View looking west northwest.
Hope this helps.
Thanks!
