(Sunday, February 2, 1913, 12:01 a.m. EST) — New York City’s rebuilt Grand Central Terminal, a commuter rail terminal located at 42nd Street and Park Avenue in Midtown Manhattan, New York City, officially opened to the public today at one minute past midnight.

The terminal was built on the site of two similarly-named predecessor stations, the first of which dated to 1871.

Grand Central is the southern terminus of the Metro-North Railroad’s Harlem, Hudson, and New Haven Lines, serving the northern parts of the New York metropolitan area.

It also contains a connection to the New York City Subway at Grand Central–42nd Street station. The terminal is the second-busiest train station in North America, after New York Penn Station.

Grand Central covers 48 acres and has 44 platforms, more than any other railroad station in the world. Its platforms, all below ground, serve 30 tracks on the upper level and 26 on the lower. In total, there are 67 tracks, including a rail yard and sidings; of these, 43 tracks are in use for passenger service, while the remaining two dozen are used to store trains.

Another eight tracks and four platforms are being built on two new levels deep underneath the existing station as part of East Side Access.
