(NEW YORK) -- A Long Island Rail Road (LIRR) commuter train crashed at Atlantic Terminal in Brooklyn, New York, Wednesday morning, injuring 103 passengers, officials said.
The worst injury is believed to be a broken leg, New York Gov. Andrew Cuomo said at a news conference Wednesday morning.
The Metropolitan Transportation Authority said none of the injuries were life threatening.
According to a spokesperson for the New York Fire Department, "One of the rails actually pierced the bottom of the train ... we are fortunate we didn't have more serious injuries."
Cuomo said the train hit the track's bumping block.
"When it hit the block, the block knocked it off the tracks," he said. "It was a train that didn’t stop when it was supposed to [and] hit the block at a fairly low rate of speed."
"As a result of the impact, the lead wheel assembly derailed as did one additional axle," the MTA said in a statement.
The cause of the crash is under investigation.
Passenger Aaron Neufeld told ABC News, "It didn't seem like we were going unusually fast . ... I don't think it was anything out of the norm." He described the impact as a "substantial jolt." He said he was thrown against the seat in front of him.
An LIRR passenger told New York ABC station WABC-TV that said she heard a big thump, describing the scene as total pandemonium. She said passengers were falling on top of each other, screaming and crying.
Another woman told WABC she believed the train was traveling at a faster speed than usual right before the crash.
About 430 passengers were on the train at the time of the derailment, according to the MTA. The incident happened on LIRR track 6 around 8:15 a.m, the MTA said. The terminal is located near the Barclays Center.
Cuomo emphasized that Wednesday's incident was "minor" compared to the crash at Hoboken Terminal in New Jersey on Sept. 29, 2016, that killed one bystander and destroyed part of the historic train terminal.
The National Transportation Safety Board and the Federal Railroad Administration are involved in the investigation.
The MTA said there were no delays Wednesday morning as result of the accident.
