 The Dauphin and Susquehanna Coal Company (D&S) operated a railroad which connected with the PRR at Rockville (where their main line crossed the Susquehanna), ran north along the river to Dauphin, and turned northeast to run up Stony Valley to the Rausch Gap coal mines.It proved to be a willing partner in the plan.The D&S and CNJ jointly procured a charter, issued April 19, 1853, for the Allentown Railroad, which would construct the first segment of the route.
