River LINE – runs mostly along Conrail's Bordentown Secondary and was purchased by NJ Transit to construct the line.Raritan Valley Line – Aldene to NK Tower (owned by Conrail).Port Jervis Line – Suffern to Port Jervis (owned by Norfolk Southern and operated by Metro North).Northeast Corridor Line – entire line (owned by Amtrak).Atlantic City Line – Philadelphia to Delair Junction (formerly owned by Conrail).The exceptions on the NJT system are the following: New Jersey Transit owns most of its tracks, infrastructure, bridges, tunnels, signals, and right-of-way, as opposed to having them leased via trackage rights from private freight railroads. An express line from New York, NY to Atlantic City was proposed in June, 2006. The Atlantic City Line, originating from Philadelphia, PA, is in neither division and is thus considered its own division. Connections to other New Jersey Transit train lines may be made at Secaucus Junction. They do not terminate at Penn Station (New York City) rather, they terminate at Hoboken Terminal. These lines are formally called the Erie Lines because their right-of-way at one time belonged to the Erie Railroad. The portion of the line from Bay Street to Newark Broad Street Station was formerly the Montclair Branch of the Morris and Essex Lines before the Montclair connection connected it to the Boonton Line. The Morris and Essex Lines consist of former Morris and Essex Railroad (later Delaware, Lackawanna and Western Railroad) lines.

This division is made up of former Erie Lackawanna Railroad lines and is further split into two sub-divisions.

The remaining lines, with the exception of Atlantic City, are in the Hoboken Division, operating out of Hoboken Terminal.

Before the formation of NJ Transit, these lines were operated by the Pennsylvania Railroad and the Central Railroad of New Jersey. The Newark Division consists of the lines operating out of Newark Penn Station. The lines are grouped into two distinct divisions. New Jersey Transit operates a rail network of 11 rail lines, 161 stations and 954 miles as of the 2003 fiscal year (June 30, 2003).
