HOBOKEN, N.J. (AP) — Federal investigators pulled one of the black box recorders from the wrecked commuter train at the Hoboken station and struggled to extract the second one Friday as they tried to figure out what caused the crash that killed one person and injured more than 100 others.
The two recorders could contain information on speed, braking and other conditions that can help investigators determine whether the tragedy resulted from an equipment malfunction or a distracted or incapacitated engineer.
Investigators from the National Transportation Safety Board will be looking to determine how fast the train was going when it crashed at the busy station Thursday morning. They hope to speak to the train's injured engineer on Friday, NTSB Vice Chairman T. Bella Dinh-Zarr said. State officials say he has been cooperating.
The investigation will seek to answer many questions, including whether a system designed to prevent accidents by overriding the engineer and automatically slowing or stopping trains that are going too fast could have helped if it had been installed on the line.
Investigators recovered an event recorder from the locomotive at the rear of the train Thursday night and will be examining it Friday, Dinh-Zarr said. The device contains information on the train's speed and braking.
But investigators are struggling to extract a recorder from the forward-facing camera in the badly mangled first car of the train without damaging it, the NTSB said Friday. That recorder should show what was ahead of the train before it crashed.
More than 100,000 people use New Jersey Transit to commute from New Jersey to New York City each day. The NJ Transit portion of the Hoboken station remained closed Friday, slowing the morning commute for those making connections there.
As investigators began their probe, the family of Fabiola Bittar de Kroon, the crash's sole fatality, was in mourning. De Kroon had recently moved to New Jersey from Brazil after her husband got a job with an international liquor company.
She had just dropped her toddler daughter off at day care before rushing to catch a train, according to day care director Karlos Magner.
"We had a good talk for like a minute," he said. "She said she was in a rush."
Shortly after, the NJ Transit train ran off the end of the track as it was pulling in around 8:45 a.m., smashing through a concrete-and-steel bumper. As it ground to a halt in the waiting area, it knocked out pillars, collapsing a section of the roof.
De Kroon was killed by debris, and 108 others were injured, mostly on the train, Gov. Chris Christie said. Scores were hospitalized, some with serious injuries including broken bones.
The engineer, Thomas Gallagher, was pulled from the mangled first car and was treated at a hospital and released. Gallagher has worked for NJ Transit for 29 years, and a union roster shows he started as an engineer about 18 years ago.
Some witnesses said they didn't hear or feel the brakes being applied. Authorities would not estimate how fast the train was going. But the speed limit heading into the station is 10 mph.
"The train came in at much too high rate of speed, and the question is: 'Why is that?'" Christie said.
New York Gov. Andrew Cuomo, a Democrat, and Christie, a Republican, cautioned against jumping to conclusions about the role that the lack of positive train control played or didn't play in the tragedy.
The NTSB has been pressing for some version of the technology for at least 40 years, and the industry is under government orders to install it, but regulators have repeatedly extended the deadline at railroads' request. The target date is now the end of 2018.
Over the past 20 years, the NTSB has listed the lack of positive train control as a contributing factor in 25 crashes. Those include the Amtrak wreck last year in Philadelphia in which a speeding train ran off the rails along a curve. Eight people were killed.
In 2011, a Port Authority Trans-Hudson, or PATH, commuter train crash in a separate section of the Hoboken station injured more than 30 people. The NTSB found the engineer failed to control the speed of the train as it entered the station and investigators also determined a contributing factor was the absence of positive train control.
"They'll have to answer for themselves, but at the end of the day if safety is job one ... then you have to have a better record than New Jersey Transit has right now," said U.S. Sen. Bob Menendez, D-N.J., noting that the transit agency said in a 2016 report with the Federal Railroad Administration that it didn't have positive train control on any locomotive or segment of track.
"That means zero across the board," he said. "They need to do better than zero across the board."
A spokeswoman for NJ Transit referred all questions about the investigation, including questions about positive train control, to the NTSB.
Even without positive train control, there are still safeguards in place in Hoboken.
NJ Transit trains have an in-cab system that is designed to alert engineers and stop locomotives when they go over 20 mph, according to an NJ Transit engineer who spoke on condition of anonymity because he was not authorized to discuss the accident.
Trains like the one in Thursday's crash also are equipped with a system that sounds a loud alarm and eventually stops the train if the engineer goes 15 to 20 seconds without touching the controls.
But it was unclear whether those mechanisms kicked in or whether they would have slowed the train enough in the short time it takes to traverse the station.
Tom Spina, a maintenance supervisor for a private company who was in the terminal at the time, said it was chaotic and there was a lot of yelling and screaming.
"It was chaotic. There was yelling and screaming, a lot of people in shock," Spina said.
"Things like this we see in movies," he said. "You don't think you're going to see it in real life."
