In 1983, NJT assumed operation of all commuter rail service in New Jersey from Conrail. It now operates every passenger and commuter rail line in the state except for Amtrak; the Port Authority Trans-Hudson (PATH), which is owned by the Port Authority of New York and New Jersey; the PATCO Speedline; two SEPTA Regional Rail lines, the West Trenton Line and the Trenton Line; and a handful of tourist trains in the southern and northwestern parts of New Jersey. Since inception, rail ridership has quadrupled.
