An old cart and coupler (leaning against the metal beam) sit next to PRR GG1 #4913 at the Altoona Railroader's Memorial Museum. Of special note, the coupler, from some sort of PRR rail car, was buried as the result of the great Johnstown Flood and was unearthed several years ago during an excavation project in the Johnstown, PA area and was then given to the museum.
