NJ Transit said the mishap happened at a "slow speed," around 6:20 p.m.

There were no injuries, according to a New York City fire department spokesman.

The Montclair-Boonton Line train was headed from Penn Station to Montclair State University when the derailment occurred shortly after leaving the station and before the Hudson River tunnel, NJ Transit spokesman Jim Smith said.

One set of wheels on one car, which was closed to passengers at the time, derailed, the spokesman said. There were no injuries to the approximately 900 to 1,000 passengers on the train. Read more at NJ.com
