Historic photo of the Donham Avenue Viaduct in Columbia-Tusculum, looking north northwest along the Pennsylvania/Little Miami Railroad. Note that although the main span is steel, the rest of the viaduct is wood. The caboose is on a freight siding for the IR&T. This was the primary connection for them to get coal to their power station at Coney Island.
