>> Investigators from the NTSB Friday seeking clues on why a train failed to stop at the Hoboken, New Jersey station, killing one woman and injuring 108 others.>> We have secured one of the black boxes or event recorders from the locomotive. We are waiting to make sure that the scene is safe enough so we can access the other three passenger cars.
>> The black box was removed late Thursday from the rear car of the New Jersey transit train that plowed through an end barrier and into the Hoboken Terminal building during morning rush hour. The twisted wreckage preventing investigators from reaching the other recorder in the train's front car. 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 with commuters failed to stop.
Investigators say it is too early to determine whether an anti-collision system, known as Positive Train Control or PTC, could have prevented the crash. PTC automatically applies the breaks if a train exceeds the speed limit in a section of the track. Reuters correspondent, David Shepardson covers rail safety.>> In 2008, Congress had mandated Positive Train Control in all systems by the end of 2015.
And as the end of 2015 approached, given that these various systems were not gonna have PTC in place by then. Congress delayed that requirement till the end of 2018. Under certain circumstances they can delay it all the way till the end of 2020.>> DNTSB says the investigation is expected to take seven to ten days.
New Jersey transit says the train's engineer Thomas Gallagher a 29 year old veteran of the railway is cooperating with investigators.
