>> Federal investigators have started speaking with crew members who were on the New Jersey commuter train that failed to stop at Hoboken Station during rush hour Thursday morning. The crash left one woman dead and injured more than 100 people. Late Friday NTSB Vice Chairwoman, Bella Dinh-Zarr, called the crew very cooperative.
>> We've obtained blood and urine samples from the engineer which the NTSB and FRA have sent for toxicology examination.>> As they try to figure out what caused the crash, authorities have also pulled one of the black box recorders from wrecked train, sending it to the manufacturer to download information, including the speed of the train as it approached the terminal.
So far they haven't gotten to a second recorder, stuck in the twisted wreckage still too unsafe to enter until more debris is moved out of the way, a process that could take at least another day.>> Because of the asbestos, and because of the unsettled structures that we're not sure about, I'm not allowing anybody to go in there, okay?
None of the evidence that's in there is perishable.>> It's too early to say if an anti-collision system known as positive train controller, or PTC, could have prevented the crash. It's designed to stop a train if the driver misses a stop signal. Friday train service was still suspended in and out of the terminal, one the New York area's busiest.
