 One of these new lines was the Atglen and Susquehanna Branch, which left the Main Line at Parkesburg to cut cross-county to the Susquehanna River, followed the east bank of the river to Marietta, crossed the river and ran along the west bank to Wago Junction, where it met the Northern Central Railway.The line from Marietta to Wago Junction was chartered as the York Haven and Rowenna Railroad, and much of the construction, including the crossing of the Susquehanna at Shocks Mills, was done by H.S.Kerbaugh, a major PRR contractor.
