Grand Central Terminal (GCT, often called Grand Central Station or simply Grand Central) is a terminal station at 42nd Street and Park Avenue in Midtown Manhattan in New York City. Built and named by the New York Central Railroad at the height of U.S. long-distance rail travel, it is the largest train station in the world in number of platforms:3 44, with 67 tracks along the station. There are two levels, both underground, with 41 tracks on the upper level and 26 on the lower level. When the new Long Island Railway station opens under the existing levels (see East Side Access), Grand Central station will have a total of 75 tracks and 48 platforms. Its brick vaults, patented by Rafael Guastavino, known as ‘The Architect of New York’, are characteristic.
It serves passengers travelling on the Metro-North Railroad to Westchester, Putnam and Dutchess counties in New York State, and Fairfield and New Haven counties in Connecticut.
