Via the Port Reading Railroad and the affiliated Port Reading shipping terminal (which was also built by the Reading Railroad) along the Arthur Kill waterway, trains from the Reading Railroad's Trenton line (originally the Delaware and Bound Brook Railroad) were capable of providing through service to/from the New York ports to points south and west, via a connection along the Raritan River from Manville, New Jersey to Bound Brook that was built between the Reading Railroad's Trenton line and the newly built Port Reading Railroad. Remnants of this connection, such as decaying trestles and track, can still be seen along the CSX/NS mainline through this area. The structures closest to the river are the former Reading Railroad connection.
