I know that there have been responses to this...but there are no HOLES in that windshield. In order for a projectile to get to the engineer, it would have had to make a hole. All we see is a tempered glass windshield that has been damaged by something. And of course, that projectile would still be in the cockpit - and they would have the answer.
And I also agree with the poster who said that the video should have proof, since it was a front facing camera.
I just don't believe that this man would have been so distracted by something hitting his windshield that he forgot where he was.
I really wish someone could answer how far down the track you can see. This is a main point that I haven't seen answered.
IMO, this is a tragic accident caused by human error. Like most of you. Is it better if he got distracted by something and forgot where he was along the track? If an engineer is so easily distracted, does that mean you want them in charge of YOUR train?
ETA - and to those that think he was so distracted...is it OK that when someone is so distracted, they choose to speed up? I would think instinct would be to slow down to see if there was more complicated damage.
