Although the Penn Central and the Pennsylvania-Reading Seashore Lines both rostered Baldwin locomotives, It is not generally thought that any of them were active after those lines were succeeded by Conrail. The Ironton Railroad, a short line based in Hokendauqua, Pennsylvania, was jointly owned by the Reading and the Lehigh Valley, and rostered a single locomotive, a DS-4-4-1000.
The Baldwin was assigned to local service in the Allentown/Bethlehem area, and was to be run until it failed. Here, almost a year later, Ironton 751 is near JU tower in Bethlehem, waiting for a signal to go to either Allentown Yard or Bethlehem Engine Terminal. In another year, it would be in the Altoona scrap line.
