Shared Assets Area along the National Docks Secondary. At Brooklyn, end connections are made to the New York and Atlantic Railway's Bay Ridge Branch and the South Brooklyn Railway. The crossing takes approximately 45 minutes. The equivalent truck trip would be 35 to long. Freight rail has never used the New York Tunnel Extension under the Hudson Palisades, Hudson River, Manhattan, and East River due to electrified lines and lack of ventilation. Overland travel crosses the Hudson River 140 miles (225 km) to the north using a right of way known as the Selkirk hurdle. The Cross-Harbor Rail Tunnel is a proposed rail tunnel under the Upper Bay. The western portal would be located at Greenville Yard, while the eastern portal is undetermined and a source of controversy. In May 2010, the Port Authority announced that it would purchase the Greenville Yard and build a new barge-to-rail facility there, as well as improve the existing railcar float system. The barge-to-rail facility is expected to handle an estimated 60,000 to 90,000 containers of solid waste per year from New York City, eliminating up to 360,000 trash truck trips a year. The authority's board authorized $118.1 million for the project. The National Docks Secondary rail line is being upgraded in anticipation of expanded volumes. In September 2014, the PANYNJ announced a $356 million capital project to upgrade and expand the facility, including Roll-on/roll-off operations. Expected to be operational about July 2016, an initial capacity of at least 125,000 cargo container lifts a year is projected. Port Inland Distribution Network The Port Inland Distribution Network involves new or expanded transportation systems for redistribution by barge and rail for the shipped goods and containers that are delivered at area ports in an effort to curtail the use of trucks and their burden on the environment, traffic, and highway systems. The Port Authority of New York and New Jersey (PANYNJ), New Jersey Department of Transportation (NJDOT), and Delaware Valley Regional Planning Commission (DVRPC), are involved in initiatives to review and develop this network. To instantiate PIDN, the PANYNJ signed an agreement November 29, 2003 with the Port of Albany to provide twice weekly barge service. By 2014, the service had been discontinued. In 2018, service between Newark and Brooklyn to Port of Davisville in Rhode Island was initiated.
