The East River Tunnels are 4 single-track railroad tunnels that extend from the eastern end of Pennsylvania Station under 32nd and 33rd Streets in Manhattan and cross the East River to Long Island City in Queens. The tracks carry Long Island Rail Road and Amtrak trains travelling to and from Penn Station and points to the north and east. The tracks also carry New Jersey Transit trains deadheading to Sunnyside Yard. They are part of Amtrak's Northeast Corridor; trains travelling between New York City and Boston, among other destinations, use the tunnels on their way to and from the Hell Gate Bridge. The tunnels were built in the first decade of the 20th century as part of the Pennsylvania Tunnel and Terminal Railroad, providing a connection between the Pennsylvania Railroad's train station in New York City, Pennsylvania Station, and the railroad's Sunnyside Yard.
