I'm not sure, but it also looks like there's a consolidated (C.O.T.S.) stencil on the caboose, along with a too-modern style of lettering on the U.P. gondola (left rear of the photo). There are also no roofwalks on the boxcars in the background, and what appears to be a liquified gas (high pressure) tank car visible between the buildings (it does have a frame, though, so it may have been around in the late '50s). On the next track beyond the tank car, there is also what appears to be a centre-beam flatcar, loaded with wrapped lumber or other building material .
