The Hell Gate Line is the portion of Amtrak's high-speed Northeast Corridor between Harold Interlocking in Sunnyside, Queens and in New Rochelle, New York. The first portion of the line was built by the Harlem River and Port Chester Railroad, and opened in 1873 as the Harlem River Branch of the New York, New Haven and Hartford Railroad. Commuter service ran along the line from the Harlem River Terminal up to main-line New Haven in New Rochelle until 1931. Electrified service on the line began in 1911, and the line was extended to Penn Station across the Hell Gate with the completion of the Hell Gate Bridge. Metro-North Railroad is currently planning to reinstitute local commuter service on the line as part of the first phase of Penn Station Access.
