The Metro-North Commuter Railroad (reporting mark MNCW), trading as MTA Metro-North Railroad or Metro-North, is a suburban commuter rail service run by the Metropolitan Transportation Authority (MTA), an authority of New York State. It is the second busiest commuter railroad in the United States in terms of monthly ridership, behind its sister railroad, the Long Island Rail Road. Metro–North runs service between New York City and its northern suburbs in New York and Connecticut, including, in New York State, Port Jervis, Spring Valley, Poughkeepsie, White Plains, and Wassaic; in Connecticut, New Canaan, Danbury, Waterbury, and New Haven. Metro-North also provides local rail service within New York City with a reduced fare. There are 122 stations on Metro-North Railroad's five active lines (plus the Meadowlands Rail Line), which operate on more than 775 miles (1,247 km) of track, with the passenger railroad system totaling 385 miles (620 km) of route.
The MTA also operates New York City Transit subways and buses, and the Long Island Rail Road, and has jurisdiction, through Metro-North, over railroad lines on the western and eastern portions of the Hudson River in New York State. Service on the western side of the Hudson is operated by New Jersey Transit under contract with the MTA. Metro-North operates 124 stations.
