According to the old photo caption, this was Railcar #1. I'm dubious; see the WIki writeup at en.wikipedia.org/wiki/Galloping_Goose_(railcar) . My guess this is one of the later Pierce-Arrow derivations. There were a total of 7 of these built in the railroad's Ridgway shops to hold onto the vital Post Office contract to serve the Colo. mountain towns. They did their job admirably. Remarkably, all 7 survive, in one form or another. All still run! Must be a trick, finding parts for a 1930s Pierce-Arrow.
