Access to the Region's Core (ARC) was a commuter rail project to increase passenger service capacity on New Jersey Transit (NJT) between Secaucus Junction in New Jersey and Manhattan in New York City. New infrastructure would have included new trackage, a new rail yard, and a tunnel under the Hudson River. A new station adjacent to New York Penn Station was to be constructed as running more trains into the current station was deemed unfeasible. An estimated budget for the project was $8.7 billion. Construction began in mid-2009 and the project was slated for completion in 2018, but it was cancelled in October 2010 by Governor Chris Christie, citing the possibility of cost overruns and the state's lack of funds.
