GP7 509 at Sapulpa, Oklahoma (date unknown).
The train is headed north and has just crossed Dewey Street. The small brick building left of the locomotive is part of the Tulsa-Sapulpa Union Railway engine facilities and still stands today. The tower in the background is from the glass plant.
This photograph was taken inside the wye about at the location where the depot once stood.
Special thanks to Paul Slavens.
