NEW YORK - The "summer of hell" at Penn Station has not officially begun but Thursday night was a hellish experience for some commuters after a New Jersey Transit train derailed.

No one was hurt when the train came off the tracks around 9:15 p.m.

But nearly 200 passengers had to be removed to another train.

Service in and out of Penn Station was suspended and re-routed through Hoboken for several hours as crews worked to repair the damage.

As of 7: 30 a.m. NJ Transit says service into and out of Penn Station is operating on or close schedule.

Thursday night's derailment was the third for New Jersey Transit since March.

The problems at Penn Station forced Amtrak to create an expedited work schedule to speed up critical repairs this summer.

The first phase of the work begins Monday and runs through July 25.

The second phase runs from August 4 through August 28.

The repair work at Penn Station will force several tracks to be closed at a time, and that will mean major service disruptions for commuters.

Summer of Hell: What to Expect 

Starting Monday, Manhattan-bound New Jersey Transit trains on the Morris and Essex lines will be rerouted to Hoboken, where tickets will be cross-honored on PATH trains and New York Waterway ferries.

Long Island Rail Road service in and out of Penn Station will be reduced by about 20 percent. 

MTA Chairman Joe Lhota says two more cars will be added to all trains to increase capacity on the trains that are still running.  

Two trains into Penn will be canceled every weekday morning.

Thirteen westbound trains will terminate at Atlantic Terminal in Brooklyn, Hunters Point in Queens, or Jamaica Station.

But three new trains will be added early in the rush hour.

In the evening, seven trains out of Penn will be canceled.

Ten more eastbound trains will originate in Brooklyn and Queens instead of Penn Station.

Two trains will be added.

The MTA will launch two new ferry routes to 34th Street from Long Island City and from Glen Cove on Long Island.

And it's creating new park and ride bus options throughout Nassau and Suffolk Counties.

The MTA is also offering free morning subway transfers to all Long Island Rail Road ticketholders at Hunterspoint Avenue, Jamaica Station and Atlantic Terminal.

The plan will last until at least September 1.
