On a truly spectacular summer afternoon, Norfolk Southern train 10K (Conway, PA-Allentown, PA manifest) crosses the Susquehanna River eastbound by way of the longest stone masonry arch railroad viaduct ever built: the Rockville Bridge! The bridge crosses the river about 5 miles north of Harrisburg, Pennsylvania. The eastern end is in Rockville and the western end is just south of Marysville. I really like seeing these white striped dash 9s like the one trailing on this train. They won't be around forever.
