Metro-North Railroad's Hudson Line is a commuter rail line running north from New York City along the east shore of the Hudson River. Metro-North service ends at Poughkeepsie, with Amtrak's Empire Corridor trains continuing north to and beyond Albany. The line was originally the Hudson River Railroad (and the Spuyten Duyvil and Port Morris Railroad south of Spuyten Duyvil), and eventually became the Hudson Division of the New York Central Railroad. It runs along what was the far southern leg of the Central's famed "Water Level Route" to Chicago.
