Topic - Gateway Tunnel

The Gateway Program (originally Gateway Project) is the planned phased expansion and renovation of the Northeast Corridor (NEC) rail line between Newark, New Jersey, and New York City, New York. The right-of-way runs between Newark Penn Station and New York Penn Station (NYP). The project would build new rail bridges in the New Jersey Meadowlands and new tunnels under Bergen Hill (Hudson Palisades) and the Hudson River, and expand NYP through conversion of part of the James Farley Post Office into a train station and construction a terminal annex. - Source: Wikipedia
