HOBOKEN, N.J. (AP) — A commuter train from New York barreled into a New Jersey rail station during the Thursday morning rush hour, causing an unknown number of injuries. Witnesses reported seeing one woman trapped under concrete and many people bleeding.

The train was on the NJ Transit Pascack Valley line.

A local CBS station in New Jersey is reporting that three people are dead and many of the injuries are critical.

A New Jersey Transit spokeswoman says that more than 100 people were injured, some critically, when a commuter train plowed into the Hoboken station.

The train from New York crashed during the Thursday morning rush hour. It caused serious damage to both the train and station. Witnesses reported injuries, including one woman who was trapped under concrete and many people bleeding.

The spokeswoman, Jennifer Nelson, says she doesn’t know yet how fast the train was going when it ran into the rail bumper at the end of the line.

TV footage and photos from the scene show damage to the rail car and extensive structural damage to the Hoboken station. Images on social media show a train that appears to have gone through the bumper stop at the end of a track.

“The next thing I know, we are plowing through the platform,” passenger Bhagyesh Shah told NBC New York. “It was for a couple seconds, but it felt like an eternity.”

Nancy Bido, a passenger on the train, told WNBC-TV in New York that train didn’t slow as it pulled into the station. “It just never stopped. It was going really fast and the terminal was basically the brake for the train,” she said.

He said the train was crowded, particularly the first two cars, because they make for an easy exit into the Hoboken station and onto the PATH train. Passengers in the second car broke the emergency windows to get out.

“I saw a woman pinned under concrete,” Shah told NBC New York. “A lot of people were bleeding; one guy was crying.”

New Jersey Transit spokeswoman Jennifer Nelson said on Fox News that there are multiple injuries, but it wasn’t immediately clear how many or how serious. She said about 250 passengers are usually on board the train around this time.

The train came to a halt in a covered area between the station’s indoor waiting area and the platform. A metal structure covering the area collapsed.

“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.”

The train had left Spring Valley, New York, at 7:23 a.m. and crashed into Hoboken Terminal at 8:45 a.m., said NJ Transit spokeswoman Nancy Snyder. She said authorities are investigating what might have caused the train to crash.

The National Transportation Safety Board was opening an investigation into the crash and will send a team of investigators to the scene, said Keith Holloway, a spokesman for the board.

The Federal Railroad Administration also dispatched investigators to the crash scene, said spokesman Matthew Lehner.

Rail service was suspended in and out of Hoboken, which is directly across the Hudson River from New York City.

The station is a hub for commuters switching from the NJ Transit system to the PATH system to head into Manhattan.

Hoboken, which is NJ Transit’s fifth-busiest stations with 15,000 boardings per weekday, is the final stop for several train lines and a transfer point for many commuters on their way to New York City.

NJ Transit provides more than 200 million passenger trips annually on bus, rail and light rail lines. More than 100,000 people use NJ Transit trains to commute from New Jersey into New York City daily.

A crash at the same station on a different train line injured more than 30 people in 2011. The PATH commuter train crashed into bumpers at the end of the tracks on a Sunday morning.
