Yes "buddy". I don't need a lecture on how living near train tracks is noisy. I've spent more time in a month around trains than most probably spend in a lifetime. I was just pointing out it's completely feasible to not hear a train approaching from behind, especially if you're wearing headphones. The guys operating three things are human also. It's possible they didn't see him. Could have been bs'ing, not paying attention, or doing a million other things. Heat rising from tracks and the perspective from being up in an engine cab can play tricks with your eyes. So while you want to be a know it all, I'm just saying the whole situation isn't that unfathomable, even though it certainly could have been avoided.
