New York City's Grand Central Terminal, the world's largest train station by number of platforms, opened immediately after midnight.

Grand Central Terminal is a commuter rail terminal at 42nd Street and Park Avenue in Midtown Manhattan, New York City. 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 serves the Long Island Rail Road through Grand Central Madison, a 16-acre (65,000 m²) addition to the station located underneath the Metro-North tracks, built from 2007 to 2023. The terminal also connects to the New York City Subway at Grand Central–42nd Street station. The terminal is the third-busiest train station in North America, after New York Penn Station and Toronto Union Station.

A railway platform is an area in a train station alongside a railway track providing convenient access to trains. Almost all stations have some form of platform, with larger stations having multiple platforms.
