Grand Central Terminal is a major commuter rail terminal in Midtown Manhattan, New York City, serving the Metro-North Railroad's Harlem, Hudson and New Haven Lines. It is the most recent of three functionally similar buildings on the same site. The current structure was built by and named for the New York Central & Hudson River Railroad, though it also served the New York, New Haven and Hartford Railroad. Passenger service has continued under the successors of the New York Central and New Haven railroads.
