flights arriving from other countries could not use Terminal A (except countries with U.S. customs preclearance), although some departing international flights used the terminal. In 2016, the Port Authority approved and announced a redevelopment plan to build a new Terminal A replacing this one. Part of Terminal A was closed for demolition on September 30, 2021. The remainder of the former Terminal A was closed to the public, and replaced with the new Terminal A on January 12, 2023. Ground transportation Train A monorail system, AirTrain Newark, connects the terminals with Newark Liberty International Airport Station. The station is served by New Jersey Transit's Northeast Corridor Line and North Jersey Coast Line, with connections to regional rail hubs such as Newark Penn Station, Secaucus Junction and New York Penn Station where transfers are available to any rail line in northern New Jersey or Long Island, New York. Amtrak's Northeast Regional and Keystone Service trains also stop at the Newark Liberty International Airport station. Passengers can ride the AirTrain for free between the terminals and the parking lots, parking garages, and rental car facilities. In September 2012, the Port Authority of New York and New Jersey announced that work would commence on a study to explore extending the PATH system to the station. The new station would be located at ground level to the west of the existing NJ Transit station. In 2014, the Board of Commissioners approved a formal proposal to extend the PATH to Newark Airport. On January 11, 2017, the Port Authority released its 10-year capital plan that included $1.7 billion for the extension. Under the plan, construction was projected to start in 2020, with service in 2026. construction has yet to begin due to funding issues. In January 2019, New Jersey Governor Phil Murphy announced a plan for a $2 billion replacement project for AirTrain Newark. Murphy stated that replacement is necessary because the system is reaching the end of its projected 25-year life and is subject to persistent delays and breakdowns. The Port Authority would be responsible for funding the project. In October 2019, the Port Authority board approved the replacement project with an estimated cost of $2.05 billion. On May 5, 2021, the Port Authority issued requests for proposals to four teams. Bus NJT buses operate northbound local service to Irvington, Downtown Newark and Newark Penn Station, where connections are available to the PATH and
