That station was built and owned by the Pennsylvania Railroad; in the era of private operation passengers could transfer between the two.

The CNJ right-of-way in Elizabeth is unused, and passenger trains which served the former CNJ mainline (NJT's Raritan Valley Line service) bypass Elizabeth via the Aldene Connection on their way to Newark Penn Station.

The CNJ station suffered from a freight train wreck on November 4, 1972, when a boxcar derailed and pulled several other cars into the canopy.

[3][5][6][7] There are plans to redesign the public space and create a transit plaza between the CNJ and NJT stations.

[14][15][16] The proposed Union County Light Rail, which would have connected midtown Elizabeth with Newark Airport, would have had its western terminus at this station.
