Train delays and cancellations at Penn Station are expected to impact morning commuters following Monday's minor train derailment.
New Jersey Transit said it will continue to operate on an adjusted schedule, and it is increasing bus service for commuters.
The MTA said 15 morning rush hour trains on the Long Island Rail Road (LIRR) have been canceled or rerouted.
Dozens of trains were canceled and delayed throughout the Monday evening because of the derailment, leaving commuters frustrated.
Investigators are looking into the cause of the derailment involving a New Jersey Transit train at Penn Station.
It happened around 9 a.m. The city fire department says five people suffered minor injuries.
Close to 1,200 people were onboard. Passengers who spoke with NY1 said it was a frightening experience.
"A lot of shaking, you could tell the train was getting off the tracks," one said.
"We were slowing down coming into Penn Station, but we were still going pretty fast, it was quite jolting," said another passenger. "The train started shaking, and we actually got jolted by it."
Monday's derailment comes less than two weeks after an Amtrak train jumped the tracks as it pulled out of Penn Station.
The derailment caused it to scrape the side of an incoming New Jersey Transit train.
No serious injuries were reported in the March 24 incident.
