Located at 42^nd St. and Park Ave. in midtown Manhattan, New York City, Grand Central Terminal was built by and named for the New York Central Railroad in 1913, replacing Grand Central Station, which replaced Grand Central Depot. During the heyday of American railroad travel, Grand Central had 44 platforms, serving 67 tracks – the largest such facility in the world. The terminal has two levels, both underground, and covers some 48 acres. It currently serves commuters on the Metro-North Railroad to Westchester, Putnam, and Dutchess counties in New York and Fairfield and New Haven counties in Connecticut. Amtrak moved its operations from Grand Central Terminal to Pennsylvania Station in 1991.
