good morning from the studio 57 news room at cbs news headquarters here in new york. good to be with you. i'm anne-marie greene. the national transportation safety board says preliminary data says the amtrak train that derailed was going 80 miles an hour in a 30-mile-per-hour zone. at least three people were killed as it hit a new bypass just south of seattle. more than 70 were injured when 12 train cars and a locomotive jumped the rail, some cars falling to the road below. immediately after the derailment, the conductor called for help. >> we were coming around the corn eaer and we went on the ground. >> is everybody okay? >> i'm still figuring that out. we got cars everywhere and down on to the highway. >> the ntsb says it's not known what caused the train to derail and it's too early to know why

it was going so fast. kenneth craig is in washington with the latest. good morning. >> reporter: good morning to you, ann marie. still a massive scene out here and this is where it all happened. take a look down the interstate here. you can see that crumbled mess of a train that we now know was going 50 miles an hour faster than it should have been. >> investigators trying to figure out what caused the train derailment in washington state that killed at least three say they have recovered the event data recorder from the rear of the train. the national transportation safety board says information so far indicates speed may have played a role. >> preliminary indications are that the train was traveling at 80 miles per hour in a 30-mile-per-hour track. >> reporter: this was the first trip for the new seattle to portland route. one local official seems to have predict just a few weeks ago that something like this would happen.

don anderson had been very vocal at a city council meeting earlier this month warning of the damages of utilizing freight rail tracks for a high speed passenger rail line. but the tracks have been upgraded so officials weren't concerned about derailment but rather bringing a fast moving train so close to pedestrians and cars. 14 of the cars wentz off the tracks at an overpass, some tumbling on to interstate 5. >> the train just started to -- seemed like go off on its side and then all of a sudden it went dark and stuff started flying around. >> reporter: investigators say it may take months before they know precisely what caused the accident. >> the highway behind me came to a stand still when this all happened yesterday morning. it is still closed right now and will likely be shut down through the morning commute. >> thank you so much, kenneth. amtrak's president says an

automatic speed check technology called positive train control was not in use on the stretch of track where the derailment occurred. debra hearseman explains. >> it was really too early to tell if positive train control could have prevented this derailment because we don't know what caused the derailment. positive train control is really a backup to the human being. the engineer in the cab could be distracted or incapacitated. it's technology that knows if trains are going to collide with one another or if trains are speeding over what's permitted in that section of track. ahead on cbs this morning, we'll get an update from a member of the national transportation safety board on the scene of the derailment. and now to washington where it appears this morning that the republican controlled congress is on the verge of passing sweeping tax reform legislation. the house is expected to vote
