Harlem–125th Street station

The Harlem–125th Street station is a commuter rail stop serving the Metro-North Railroad's Hudson, Harlem, and New Haven Lines. It is located at East 125th Street and Park Avenue in East Harlem, Manhattan, New York City. The station also serves as an important transfer point between the Metro-North trains and the New York City Subway's IRT Lexington Avenue Line for access to the Upper East Side of Manhattan. It is the only station besides Grand Central Terminal that serves all three lines east of the Hudson River. Trains leave for Grand Central Terminal, as well as to the Bronx and the northern suburbs, regularly.

The current station was built in 1896–97 and designed by Morgan O'Brien, New York Central and Hudson River Railroad principal architect. It replaced an earlier one that was built in 1874 when the New York Central and the New York, New Haven & Hartford Railroad, the ancestors of today's Metro-North, moved the tracks from an open cut to the present-day elevated viaduct. The original station on the site was built in 1844, when the trains ran at grade-level on what is now Park Avenue. That station was demolished to make way for the open cut.
