Six Arches To The Susquehanna. Amtrak Train 42 (Norfolk Southern Train 04T) crosses Shermans Creek in Duncannon, Pennsylvania on the afternoon of Friday, November 20, 2020 (AMTK 94, P42DC leading). To the right, the creek meets with the Susquehanna River. This bridge is a smaller but very similarly constructed stone masonry arch railroad viaduct to the Rockville Bridge in Marysville, Pennsylvania.
The electrified Northeast Corridor and Keystone Corridor have the traffic. The Pennsylvanian and Capitol Limited routed, which are all diesel, have the scenery.
