Transcript for NTSB Investigator Says 'We Have Not Talked to Engineer'
on the rails. ABC's David Kerley is there and David, I can imagine that the ntsb is anxious to talk to the engineer. Reporter: Absolutely, robin. We now know what happened. Speed was involved here. Twice the limit on the corner just on the other side of those Bui buildings. The question is why. I just spoke with a member from the ntsb board who is here about what they want to do, what they want to learn from that engineer. We have not interviewed the engineer. We look forward to that opportunity. It's not unusual for somebody who has been through a traumatic event to some memory loss, at least short term memory loss. Reporter: Will they speak to him today? It's a possibility. That's unlikely. They may wait a day or two until he recoverers a little bit more. You mentioned infrastructure. That is a with some of the rails. Paula mentioned positive train control. All rails are supposed to visit by the end of this year. The ntsb does not believe they'll meet that deadline. It's the rail telling the train, you're going too fast and it slows it down. It's not on that piece of track behind us. Thank you, David. We move on to the dangerous flooding in the south.
