Grand Central Madison is a commuter rail terminal for the Long Island Rail Road (LIRR) in the Midtown East neighborhood of Manhattan in New York City. Part of the East Side Access project, the new terminal started construction in 2008 and opened on January 25, 2023. The station sits beneath Grand Central Terminal, which serves the MTA's Metro-North Railroad. Grand Central Madison was built to reduce travel times to and from Manhattan's East Side and to ease congestion at Penn Station, the West Side station where all Manhattan-bound LIRR trains had terminated since 1910. The new terminal enables passengers to transfer to Metro-North's Harlem, Hudson, and New Haven Lines, as well as the New York City Subway at Grand Central–42nd Street station. From Wikipedia
