Here's another shot from an old 35mm negative On the sleeve, in my dad's handwriting are, "Long Drag 1953". At first glance, I thought that this was the West Yards in Springfield, but after a closer look, I am not so sure. During this time period my father was doing a lot of work in Wichita, so perhaps that is the location. Any thoughts? It's hard to discern, but the lead unit ( an FP-7?) is flying white flags.
