Timeline of Jersey City, New Jersey-area railroads

For the purposes of this article, the Jersey City area extends North to Edgewater (the Northern end of the line along the Hudson River), South to Bayonne and includes Kearny Junction and Harrison but not Newark.

A short, partially elevated track, known as the Marion Running Track, is built to connect the ex-PRR Passaic and Harsimus Line from Kearny to the ex-Erie Northern Branch.

This reconfiguration provided the ex-NYC West Shore (aka River Line) with a more direct connection to other lines heading west and south at Marion Junction.

CSX River line is shifted to the re-newed Northern Running track to North Bergen Yard.

On October 7, 2010, New Jersey governor Chris Christie announced that the Access to the Region's Core, which included a new right-of way from Secaucus Junction under the Hudson Palisades and Hudson River to Midtown Manhattan was officially cancelled.
