Norfolk Southern Railway (NS) shares the use of the track for local freight operations between Suffern and Port Jervis. The New York, Susquehanna and Western Railway operates over the line between Hudson Junction (east of Campbell Hall) and Port Jervis, and onward to Binghamton over the former Erie Railroad Delaware Division. The tracks have been owned by NS since the 1999 split of Conrail, but were built by the New York and Erie Rail Road and incorporated into Conrail on its formation on April 1, 1976. Metro-North leased the entire line from NS in 2003, with the possibility of outright purchase after 2006. Since 2003, MNRR immediately began a substantial track and signal improvement program in order to provide a more reliable and comfortable service for $183 million.
