More than 100 people were injured Wednesday when a Long Island Rail Road train crashed through a bumper at the end of the line during morning rush, authorities said.

The most severe injury appeared to be a possible broken leg; no injuries were life-threatening, Gov. Andrew Cuomo said. He said Brooklyn's Atlantic Terminal suffered minor damage, but the afternoon commute would not be affected.

"A broken leg is not good, but we've been through situations where we've had worse," Cuomo said.

FDNY Deputy Assistant Chief Daniel Donoghue said more than 600 people were on the train when it smashed through the last bumper and crashed into a small room at the end of the track. He put the injury total at 76; the Fire Department later tweeted that 103 people were hurt.

"We were fortunate we didn't have more severe injuries," Donoghue said. "When we got there, there were a lot of people that needed help."

Cuomo said the train only overshot its stopping zone by a few feet and didn't derail until it hit the bumper. Most of the passengers were able to exit the train and walk away, he said.

“I was getting up from my seat and there was a loud impact, and I flew forward and then flew backward,” a passenger named Amanda told CBS2. “It was total chaos, there was smoke on the train, and we were sitting there in shock.”

The National Transportation Safety Board said it was sending a go-team to New York to begin an investigation. The crash comes three months after a New Jersey Transit train slammed through the Hoboken Terminal, killing one woman on the platform and injuring 114 people on the train.

The NTSB has yet to announce its findings on that crash. Jack Arseneault , lawyer for train engineer Thomas Gallagher, has said his client "very likely suffers from sleep apnea" that could have been a factor.

Cuomo said the accident Wednesday was not nearly as serious.

"That train was coming in much faster, caused much more damage and hurt many more people," Cuomo said. "All things considered, this (crash Wednesday) was a relatively minor accident."

LIRR, part of New York's Metropolitan Transportation Authority, claims on its website to be the busiest railroad in North America. Its 735 weekday trains transport about 265,000 customers on 700 miles of track. Its reach stretches 120 miles from Montauk on Long Island's eastern tip to Penn Station in Manhattan and Atlantic Terminal in Brooklyn.
