Local media are reporting "major structural damage" and "multiple injuries," while the first responders are setting up triage.
Eleven patients are undergoing emergency treatment - 3 of them are in critical condition, and 8 were said to be in serious condition. Another 40 are "walking wounded" with minor injuries, said officials at Jersey City Medical Center.
Emergency responder traffic spoke of three dead, but that figure could not be immediately confirmed.
The accident occurred around 8:45 am local time, and involved the 1614 train on the Pascack Valley Line. Photos show that the lead car car 6036 - an Alstom Comet V model - hit the wall of the terminal. The engine was in the back of the train as it entered the station.
The cause of the crash is still unknown. NJ Transit trains are not equipped with Positive Train Control (PTC) system, according to News 12 New Jersey reporter Walt Kane. PTC is designed to stop the train automatically in case the operator becomes incapacitated.
Preliminary reports said "approximately 100 victims." Officials have confirmed more than 100 people were injured, and that everyone has been evacuated from the train.
Several people who were on the train tweeted they felt "lucky to be alive."
Images of the accident posted on social media showed mangled metal, wires and debris scattered all over the floor. It appears the impact was powerful enough to bring down part of the ceiling.
"It simply did not stop," WFAN anchor John Minko, who witnessed the crash, told 1010 WINS. "It went right through the barriers and into the reception area."
Hoboken terminal is a major transit hub for New Jersey commuters traveling to and from New York City. More than 50,000 people use the terminal daily making it the busiest railroad station in New Jersey and the state's second busiest transportation facility after Newark Liberty International Airport, according to New Jersey transit.
All NJ Transit trains are being held at Secaucus station. PATH train service to New York City has been suspended from Hoboken station. New York Waterway ferry is accepting all rail tickets and passes at the momnet, NJ Transit said.
Comment: RT also has posted a bunch of videos showing the aftermath of the crash, while a NJ transit worker said that it was "one of the worst days I've seen" and eyewitness accounts reveal the train didn't stop before crashing into the train station, leaving passengers bloodied and people on the platform hit by falling debris from the ceiling.
