MANHATTAN — A train derailed at Penn Station on Thursday night.

It was classified as a “slow speed derailment.” No injuries were reported and riders on the train told PIX11 News that the air-conditioning and power were operational during the more than 2-hour ordeal.

The New Jersey Transit train derailed on Track 11 as it was approaching the platform, officials said.

The train left Long Branch around 7:20 p.m. and was scheduled to arrive at Penn Station around 8:53. It derailed with about 180 passengers on board around 9:10 p.m. Emergency crews and FDNY crews assisted those passengers.

The derailment shut down New Jersey Transit service into the night but it did not directly impact LIRR service. Riders should check reports and alerts from the railroads and Amtrak for the Friday morning rush hour.

Speed restrictions have been put back into place at Penn Station. Crews will repair the section and check other track areas.

On Monday, extensive track repairs will start at Penn Station. Amtrak owns and operates the facility.

Amtrak lifted a speed restriction for trains heading into Penn Station on Sunday. The 10 mph speed limit was in place after a series of derailments earlier this year and during a period of preparation for this month’s major repair project. The speed limit usually 15 mph.

More than 600,000 people go through Penn Station daily — more than LaGuardia, JFK and Newark airports combined.

There have been several derailments at Penn Station over the last year. An April 3 derailment, blamed on weakened wooden cross-ties beneath a portion of track, knocked out eight of the station’s 21 tracks for four days and created widespread delays for commuters and travelers up and down the Northeast Corridor.
