The event recorder was removed late on Thursday from the locomotive at the rear of the NJ Transit train that slammed through a barrier at the end of the track and into the Hoboken station during the morning rush hour, National Transportation Safety Board spokesman Christopher O'Neil said.
He said debris from the crash, with beams supporting the roof down and wreckage strewn about the site of the historic Beaux Arts rail terminal Cheap Nike Air Max Shoes , was preventing investigators from reaching a second recorder in the train's front car. It may not be until Saturday that the device is recovered.
The recorders hold data that includes the train's speed, throttle position and use of brakes and could offer clues as to why the train, crowded mainly with commuters heading into Manhattan, failed to stop.
NTSB Vice Chairman Bella Dinh-Zarr said the investigation was expected to take seven to 10 days. The agency scheduled a news conference for 5:30 p.m. EDT on Friday.
"We've started the process and it's ongoing Cheap Mens Nike Air Max ," O'Neil said. "There are some structural issues there, and the structure is unsafe, potential for collapse, that kind of thing. So that has to be resolved. We want to get there as quickly as possible Cheap Womens Nike Air Max , but we want to get there safe," O'Neil said.
Train No. 1614, originating in Spring Valley, New York Cheap Nike Air Max , was at the end of its 17-stop hour-long southward journey when it crashed, toppling support columns in the early 20th century building. Witnesses described a scene of horror and chaos.
Witnesses and officials said the train came into the station too fast and never slowed, but it was unclear why.
It was too early to say whether an anti-collision system known as positive train control (PTC) could have prevented the crash, they said. PTC is designed to halt a train if the driver misses a stop signal Cheap Air Max Canada , and advocates say it helps to address human error. None of NJ Transit's train are equipped with PTC.
Peter Goelz, a former NTSB managing director, said that PTC is most effective at higher speeds out on open track, adding it is far from clear it could have made a difference in Hoboken. He said other factors Cheap Air Max Shoes , such as the alertness of the
