The Metro-North Commuter Railroad (reporting mark MNCW), trading as MTA Metro-North Railroad or simply Metro-North, is a suburban commuter rail service run by the Metropolitan Transportation Authority (MTA), a public authority of the state of New York. With an average weekday ridership of 298,900 in 2014, it is the second-busiest commuter railroad in North America in terms of annual 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 124 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 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.
