Part of the route analysis is to look at the speed. That's one of the risk factors. Certainly that's something they should be looking at, but what was the speed...?
I was just asking Mr. Jang about the last cars there. For the cars you see that are very badly damaged, the ones that have derailed, the analysis has shown they were going about 20 miles per hour, so they were going very slowly. The problem with these tank cars is that they do not perform well in a derailment or a collision, even at lower speeds.
