The New Jersey Transit Corporation (usually shortened to New Jersey Transit or NJ Transit) is a statewide public transportation system serving the state of New Jersey, and Orange and Rockland counties in New York. It operates bus, light rail, and commuter rail services throughout the state, notably connecting to major commercial and employment centers both within the state and in the adjacent cities of New York and Philadelphia. All but two of NJ Transit's commuter trains feed into New York's Penn Station in Midtown Manhattan or Hoboken Terminal in Hoboken, New Jersey. The exceptions are the Atlantic City Line, which terminates at 30th Street Station in Philadelphia and the Raritan Valley Line, which terminates at Newark's Penn Station. Most NJ Transit commuter buses go to Manhattan's Port Authority Bus Terminal and to Philadelphia's Greyhound Terminal (or Market Street in Philadelphia). Covering a service area of 5,325 square miles, NJ Transit is the nation's largest statewide public transit system and the nation's third largest provider of bus, rail and light rail transit , linking major points in New Jersey, New York and Philadelphia.
