The Conrail Lehigh Line is a railroad line in the state of New Jersey operated as part of the North Jersey Shared Assets Area. It runs from Newark to Manville along the former main line of the Lehigh Valley Railroad. At CP Port Reading in Manville, the CSX Transportation (ex-Reading Railroad) Trenton Subdivision splits southward, and the Lehigh Valley-built tracks continues as the Norfolk Southern Lehigh Line.
