The accident happened at 6th Street, causing the train to derail just after 3:00 a.m.
Investigators said it appeared the driver went thru a red light.
The driver was extricated from the vehicle and hospitalized with injuries, but officials said the person is expected to survive.
There were no passengers on the train.
The light rail train was knocked off its tracks in the crash and unable to be moved for hours.
First, workers had to remove the car, which became wedged between the train and a utility pole.
They then had to get the train back on the rails and inspect the tracks before service could resume.
There were delays in both directions between Tonnelle Avenue and 8th Street in Bayonne. Buses and PATH honored light rail tickets.
