Grand Central Terminal (GCT; often called Grand Central Station or simply as Grand Central) is a terminal station at 42nd Street (Manhattan) and Park Avenue (Manhattan) in Midtown Manhattan in New York City, United States. Built and named for the New York Central Railroad at the height of long-distance rail in the United States, it is the largest train station in the world by number of platforms:[3] 44, with 67 tracks throughout 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 Rail Road station is opened below existing levels (see East Side Access) the station Grand Central will have a total of 75 tracks and 48 platforms. Its brick vaults patented by Rafael Guastavino, called "the Architect of New York", are characteristic.

It serves passengers traveling on the Metro-North Railroad to the counties of Westchester "Westchester County (New York)"), Putnam "Putnam County (New York)") and Dutchess "Dutchess County (New York)") in the state of New York "New York (State)"), and the counties of Fairfield "Fairfield County (Connecticut)") and New Haven "New Haven County (Connecticut)") in Connecticut.
