Update: According to "The Seattle Times", December 21, 3:40 P.M., Washington State Department of Transportation (WSDOT) officials "say they won't restart passenger service along the rail line where an Amtrak train derailed until "positive train control" safety systems are in place". Initial railroad plans proposed by the Washington state government would have eliminated the turn, allowing trains to safely enter the area at higher speeds, according to the Journal.
It found that positive train control (PTC), a technology that can automatically slow a train down if it senses it's going too fast, was not installed on the train.
The NTSB's findings are based on the locomotive event data recorder and inward and outward-facing cameras on the train.
The recording ended with the locomotive tilting and the crew bracing for impact, the statement said.
- The engineer "made a comment regarding an over speed condition" after six seconds before the derailment.
A video from Monday's fatal accident showed the locomotive tilting and the crew bracing for impact as it headed at 80 miles per hour into a 30 miles per hour curve in track near DuPont, Wash., according to investigators from the National Transportation Safety Board (NTSB).

NTSB added the information was preliminary and subject to change as investigators continue to look into what led to the Amtrak train's derailment. Hart told lawmakers that technology known as positive train control is created to prevent derailments caused by "over-speeding". The board has not concluded what caused the crash that killed three passengers, among the 85 passengers and crew members.
More than 70 people were injured in the Monday morning derailment, in which several train cars fell from a bridge and onto a highway in the city of DuPont, about 20 miles south of Tacoma, authorities said.
