Grand Central Terminal (GCT) — often popularly (and incorrectly) 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 by and named for the New York Central Railroad in the heyday of American long-distance passenger trains, it is the largest train station in the world by number of railway platforms: 44, with 67 tracks along them. They are on two levels, both below ground, with 41 tracks on the upper level and 26 on the lower. When the Long Island Rail Road's new station, below the existing levels, opens, Grand Central will offer a total of 75 tracks and 48 platforms. The terminal covers an area of 48 acres.
The terminal serves commuters traveling on the Metro-North
Railroad to Westchester County, New York, Putnam County, New York,
and Dutchess County, New York in New York State,
and Fairfield County, Connecticut and New Haven County, Connecticut
in the state of Connecticut.
It was built in 1871 and rebuilt in 1913. Although the terminal
has been properly called "Grand Central Terminal" since 1913, many
people continue to refer to it as "Grand Central Station".
Technically, "Grand Central Station" is the name of the nearby post
office, and of a New York City subway station at the same location.
The 1871 rail station on the site was "Grand Central Depot".
