The New York Branch or the Bound Brook Route was a railway line in Pennsylvania and New Jersey. It was operated by the Reading Company and owned by two of its subsidiaries, the North Pennsylvania Railroad and the Delaware and Bound Brook Railroad. It formed part of the Reading's route from Philadelphia to New York City, used by the famed Crusader. The line was transferred to Conrail in 1976 and was split into the Neshaminy Line and Trenton Line. SEPTA continues to operate commuter trains to West Trenton as part of its West Trenton Line.

The Reading Company was a Philadelphia-headquartered railroad that provided passenger and freight transport in eastern Pennsylvania and neighboring states from 1924 until its acquisition by Conrail in 1976.
