GP7 570, GP7 611 and Caboose 1104 at Tulsa, OK (date unknown).
The location is Tulsa with the caboose hop headed east with the Arkansas River bridge just ahead after rounding a curve to the right. The highway bridge in the background is I-244 between the river and 17th St. When I enlarged the photo, I can see the Citgo headquarters building above the rear of the cab and the 4th National Bank building between the trees just behind the cupola.
Special thanks to Terry Jankowski and Karl Brand.
