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. $600 million had been spent on the project.
