TAPPER: We're back with the national lead. New details about that speeding Amtrak train that crashed in Washington state, killing three people. As a crane carefully moved pieces of the wreckage today, we learned the event data recorder clocked the train going at 80 miles an hour yesterday in a 30-miles-per-hour zone. We're also getting the identity of one of the three victims killed. Zach Willhoite was an IT specialist for a local transit company. He happened to be on the Amtrak train when it derails. CNN's Rene Marsh joins me now. And, Rene, you just got some new information about testing along the train's route. What did you learn?</s>RENE MARSH, CNN AVIATION AND GOVERNMENT REGULATION CORRESPONDENT: That's right. So, the company that owns the rail tracks, they spoke to us. Their name is Sound Transit. They tell CNN that the rail signals as well as the tracks, they were all new. They were replaced within the past two years. The company also says they tested an Amtrak train without passengers on board at all speed limits along the route. But tonight the question remains, what caused this deadly derailment?</s>MARSH (voice-over): Amtrak train 501 was traveling at 80 miles per hour, nearly three times the 30-mile-per-hour speed limit as it approached the curve where all but one of the train's cars jumped the tracks, plummeting on to the highway and vehicles below.</s>UNIDENTIFIED FEMALE: We'll be we hope interviewing the crew to find out if they have more information that can help us figure this out.</s>MARSH: Besides looking at whether a mechanical malfunction played a role, investigators are now focused on the crew controlling the train and whether human error caused the deadly derailment.
