I am not sure - I do not think the FBI has examined it yet - but it sure looks the same as the other two- we need to wait for FBI analysis of windsheild -
Ntsb will have no expertise in that arena!
I vote the left thing was not in accident sequence - IMO! Well see!
and the post a few back from a train engineer explained that they dont reduce throttle (sounds strange I know!) but do apply brakes before entering a curve
But Mark Rosenker, a former N.T.S.B. chairman, said the impact from a thrown object could have affected the engineer and led to the crash. He could have been startled to a point of distraction to lose situational awareness and forget that he was supposed to slow down instead of accelerating,” Mr. Rosenker said in an interview Friday.
Usually you just leave the throttle open until you get up to 80 miles per hour, then put on the brake for the curve,” he said. “Seems reasonable that something happened right about that time he would have started slowing down that kept him from taking the throttle off. He was startled by the impact or whatever. And by the time he realized it, it was too late.”

BBM I think the reason why they don't have to touch the throttle position is because electric trains use regenerative braking in which the electric traction motors are turned into electrical generators with the energy produced being fed back to the grid. Unlike conventional friction brakes which convert kinetic energy into heat - regenerative braking converts kinetic energy into electricity. This is why there is no need to change the throttle position if the intention is to resume the same high speed after coming out of the curve.
For this reason I believe that the position of the throttle during the accident sequence will not be relevant. The big question will be if regular braking was applied and when. IIRC it was reported that the Engineer applied the emergency friction braking system but I wonder if we know if he applied the regular brakes? Regenerative braking is an extremely complex system involving electro-mechanical devices and computers. I wonder if there was a failure in this system.
