JERSEY CITY, N.J. — Authorities say no one was injured and nothing was spilled when freight train cars derailed in Jersey City Saturday morning.

The derailment happened at 10:30 a.m., at the Newark Avenue crossing.

The Port Authority of New York and New Jersey spokesman, Joseph Pentangelo, says Saturday three or four Conrail freight cars came off the rails in Jersey City. He says Port Authority police report no injuries and no spilled hazardous materials.

Port Authority Trans-Hudson train service also was not disrupted.

Pentangelo says the derailment happened on lines behind Dickinson High School.

A message left with Conrail has not been returned.

Pentangelo says Port Authority police responded to a request for assistance from Jersey City officials.

It’s unclear what, if anything, was inside the derailed train cars.
