Were not casting any judgment calls at this point right now. We want to talk to this person and find out what his perspective was. What could have prevented this crash . Positive train control is exactly what would have controlled this. It was mandated by congress at the beginning of this year. It was a form of redundancy for human error so it can kick in and the train wont overspeed. How many miles has it not been installed yet . Were gathering that information now. We want to find out what percentage does have it. Thats important. Of course, this part of the track, as you know did not have the positive train control installed on it, so we wasnt to find out why. We understand there was a forward facing camera installed on the train. Were you able to look at it . It gives us one more perspective of what might have been going on. Its facing out, so we can tell perhaps the track conditions, it can tell us some of the signal indications.
