 The Cornwall & Mount Hope, long out of use, was abandoned in 1964, and part of the Mount Hope spur followed in 1971.With the formation of Conrail in 1976 and the transfer of the PRR Main Line to Amtrak, major abandonments of little-used lines began.The Lebanon Branch and the Quarryville Branch both went at its formation, although a steep spur was built off the Atglen & Susquehanna Branch at Quarryville to reach a stub of the old branch to New Providence.
