NTSB has yet to interview injured engineer in deadly crash

He hasn't spoken publicly.

Authorities want to know why the commuter train with engineer Thomas Gallagher at the controls smashed through a steel-and-concrete bumper and hurtled into the station's waiting area. The NJ Transit portion of the Hoboken station remained closed on Friday, slowing the morning commute.

The National Transportation Safety Board said Friday it could be a few days before investigators gain full access to the crash site due to a fallen canopy and debris. "The weather has been a bit of a hindrance", said Dinh-Zarr.

The young mother killed by the Hoboken train accident on Thursday morning was Brazilian Fabíola Bittar de Kroon.

The official also said Gallagher's blood and urine were sent for testing - standard procedure after an accident - but the results were not yet available.

The official, who was familiar with an audit by the Federal Railroad Administration, spoke to the AP on condition of anonymity because the official wasn't authorized to speak publicly about an ongoing investigation.

Investigators have been unable to get to the other recorder in the train's front auto because of debris.

But authorities struggled to extract a recorder from the forward-facing video camera in the train's mangled first vehicle without damaging the device.

- Associated Press writer Michael Balsamo in Hoboken contributed to this report. The front of the train was the most severely damaged in the crash, and in addition the station's canopy fell onto the front auto, making it hard for investigators to access.

Christie and New York Gov. Andrew Cuomo cautioned people to wait until investigations are completed before concluding PTC would have prevented this incident.

At about 8:45 a.m., a train traveling too fast had barreled down the tracks with such speed that it plowed into a barrier and went airborne into the station.

Speeding was the cause of both an Amtrak derailment in Philadelphia in 2015 that killed eight people and wounded 200 others and the Metro-North crash in NY in Dec 2013 which killed four people and wounded 67.

Contractors were working to prop up a canopy Friday so investigators could safely get to the front auto.

On Friday afternoon, 15 of the injured were still in the hospital, including two in intensive care.

Valle suffered a head injury and was transported to Carepoint Health Hoboken University Medical Center.

Bhagyesh Shah, who rode in the front vehicle on his way to work, said the train didn't appear to slow as it entered the station.

The 34-year-old made that kind of impression on those who knew her.

"The train came in at much too high rate of speed, and the question is: 'Why is that?'" Christie said. Although train data recorders have protective material around them to withstand an accident, the recorder can still malfunction and fail to record data or can be so badly damaged that it is hard to extract data from it.

That recorder should show what was ahead of the train before it crashed.

The recorder holds data that includes the train's speed, throttle position and use of brakes.

Officials say the one data recorder recovered so far from the New Jersey Transit commuter train that crashed in Hoboken killing one and injuring more than 100 others was not functioning the day of the accident.

National Transportation Safety Board investigators have recovered the event recorder from the train that crashed into a rail station in New Jersey. De Kroon had recently moved to New Jersey from Brazil after her husband got a job with an worldwide liquor company.

Investigators were also reviewing security video from the station, setting out to inspect the nearby tracks, and gathering records on the crew members' training, scheduling and health, Dinh-Zarr said.

"The agency has been starved", he said.
