At least one car of a New Jersey Transit train derailed at Penn Station in Manhattan at about 8:55 p.m. Thursday.

About 100 people were on board the train. The FDNY said no one was seriously hurt.

New Jersey Transit rail service is suspended in and out of Penn Station. The PATH train system is cross-honoring NJ Transit passes and tickets at 33rd Street, Hoboken, and Newark.

Penn Station is the nation's busiest train station.
