A New Jersey Transit train carrying about 150 people derailed at Penn Station on Thursday night, sources told NY1.
The derailment happened 9:15 p.m. at Track 11, according to sources.
Amtrak officials described it as a "slow speed derailment" in a statement after it happened.
Officials have not reported any injures at this time, but emergency responders had to evacuate more than one hundred people.
The derailment happened at the interlocking, which is where major repairs to some Penn Station tracks are scheduled to begin Monday.
Amtrak officials said customers between the city and New Jersey should expect "extensive delays."
NJ Transit train service is suspended in and out of the station due to the derailment, officials said.
Officials said Midtown direct trains are being diverted into HOB Terminal, and NJ Transit is cross-honoring with PATH, NJ Transit, and private bus carriers.
In time for this past Monday's AM rush, Amtrak had returned the speed limit around Penn Station to 15 MPH.
Thursday's incident marks the third derailment at Penn Station since March.
An Amtrak train side-swiped a NJ Transit train at the station March 24.
Then April 3, another NJ Transit train derailed, causing heavy delays.
NJ Transit officials said they are working with Amtrak to determine why the train derailed Thursday.
