No mechanical problems. That's the ruling from the NTSB on Sunday's deadly train derailment in New York City. YNN's Michael Herzenberg has more on investigators' findings and the condition of the man who was driving the train.
NEW YORK CITY, N.Y. -- The National Transportation Safety Board says there is no indication of brake failure in that fatal Sunday train derailment in New York City.
The NTSB says Metro-North mechanical department performed a proper brake test before the train left the station.
Investigators have begun inspecting the mechanical systems of the train cars and interviewing members of the crew, including the engineer. Alcohol and breath tests have all come back negative for all crew members. Full toxicology results, however, are still pending. That includes the train's engineer, William Rockefeller, a Metro-North employee for 15 years.
Sources YNN's sister station NY1 that Rockefeller was not sleeping, contrary to prior reports. Those sources also say that he was fully rested and not on his cell phone at the time of the crash.
The NTSB says if they had more computerized safeguards on the train, this might not have happened.
"Now many of you have asked whether or not Positive Train Control would have prevented this accident. What I can say is that for more than 20 years, the NTSB had recommended the implementation of PTC technology. Broadly speaking, we know that human error cannot be eradicated and that PTC is capable of supplementing the human operation," said Earl Weener of the NTSB.
On Monday, the NTSB told us that train was speeding at 82 MPH when it entered the curve where the crash happened. The speed limit in that zone is 30 MPH.
Four people were killed and more than 65 others were hurt.
