Federal investigators have recovered the event recorder from the train that crashed into a station in Hoboken on Thursday, killing one woman and injuring more than 100 people.

The New Jersey Transit train out of Spring Valley, New York was approaching the Hoboken Rail Terminal when it slammed into a platform just before 9 a.m. Thursday.

Officials from the National Transportation Safety Board (NTSB) arrived at the crash site a short time later.

Investigators say 34-year-old Fabiola Bittar de Kroon was killed. The Hoboken resident was standing on the platform when she was hit by falling debris.

She had just come from dropping her daughter off at daycare, and her family had just recently moved to New Jersey from Brazil.

Investigators are looking at the engineer's performance, along with the conditions of the train, track and signals.

Gov. Andrew Cuomo and New Jersey Gov. Chris Christie toured the site earlier in the day. They said the train was moving at a high speed in a 10 mph zone. The NTSB says they're still investigating that claim.

Investigators also will examine whether positive train control, a system designed to automatically slow or stop speeding trains, could have helped. The NTSB has been pushing for the technology for decades, but Congress has delayed mandating it, and no NJ Transit train has it.

Officials say 108 people were hurt, most of them with minor injuries.

66 victims were taken to the Jersey City Medical Center, and most have been treated and released.

23 patients were also treated at the Carepoint Health Hoboken University Medical Center, just blocks from the terminal.

The train's engineer, Thomas Gallagher, was also treated and released. The NTSB says he's a nearly 30-year veteran with New Jersey Transit, and that he's cooperating with their investigation.

The board is promising a thorough investigation, so that it could prevent a similar accident from happening in the future.

"We are looking into every aspect of it.  So, we like to say we look at the man, the machine and the environment," said Bella Dinh-Zarr, the vice chairwoman of the NTSB.

"So, we're going to be looking at everything from the track to the mechanics to the human performance, operations, as well as the occupant protection survival factors of this train," she added.

The effects of the crash could impact both New York and New Jersey commuters for the morning rush.

There were delays on New Jersey Transit trains for hours after the crash, but service started to get back to normal by the end of Thursday night's evening rush.

Officials expanded bus, rail and light rail service for affected commuters. They also added bus service from the Port Authority to Hoboken.

PATH service to Hoboken was also restored by late Thursday afternoon.

Extra staffers are on hand at both Penn Station and the PATH Station on Sixth Avenue to help direct travelers.

Riders who were expecting a much longer commute were pleasantly surprised.

"I heard about that, that it took about maybe two hours just waiting on a bus. That's crazy," said one commuter.

"I would have thought the bus is going to be overflowed by tomorrow morning and starting to think of alternative ways to get there, the ferry and things like that. But great news that the PATH is up and running again," said another.

Officials say New Jersey Transit rail service remains suspended in Hoboken.

The MTA says it's providing shuttle bus service for affected Metro-North customers during peak hours Friday.
