Hanna, Wyoming is, or was, a coal-mining town. Union Pacific owned the mines and consumed much of the coal in its locomotives. In this photo, note the snow fences on the ridge to keep snow out of the railway cut. The coal-burning steam locomotive in the photo represents the livelihood of Hanna. When the Union Pacific switched to diesel-electric locomotives in the 1950s, miners in Hanna lost their meal ticket.
