The Northern Branch Corridor Project is a planned extension of the Hudson-Bergen Light Rail (HBLR) from its northern terminus into eastern Bergen County, New Jersey initially proposed in 2001. If built, the new service would use the right-of-way of the Northern Branch on which the Erie Lackawanna Railroad ran passenger service until October 3, 1966 and is currently a lightly used, stub-ended freight rail line owned by CSX Transportation. The Northern Branch Corridor is at the foot of the west side of the Hudson Palisades in the Hackensack River valley, running for much of its length parallel to Overpeck Creek. After mixed reactions and extensive community input to a draft environmental impact statement (EIS), it was decided in 2013 to terminate the line at the Englewood Hospital and Medical Center. In March 2017 the Supplementary Draft Environmental Impact Statement was approved by the Federal Transit Administration allowing for a period of public reaction. A separately conceived and funded bridge necessary for operation of the system is partially built.
Original proposals for the HBLR called for a terminus at the New Jersey Turnpike Vince Lombardi Park-and-Ride in Ridgefield in Bergen County. Despite its name, it currently operates only in Hudson County. Service began its initial operating segment in April 2000, expanded in phases during the next decade, and was completed with the opening of its southern terminus on January 31, 2011. The line generally runs parallel to the Hudson River and Upper New York Bay, while its western branch and its northern end and travel through the lower Hudson Palisades. HBLR has twenty-four stations along a total trackage length of just over 21 miles (34 km) and serves over 40,000 weekday passengers. From it southern terminus at 8th Street in Bayonne the HBLR travels through Jersey City, Hoboken, and North Hudson to its current northern terminus at Tonnelle Avenue. The balloon loop allowing for reversal of direction is immediately adjacent to the proposed right of way at the North Bergen Yard.
