Joining me here on our big map is richard beal he is a railroad operation and safety expert and a former locomotive engineer. really glad to have you here. your expertise is invaluable to us at a time like this. so the animation can show sort of what happened here in terms of the 30th street station, where the train left philly. we understand it left around 9:10 about 15 minutes later is when this crash occurred. we know the train was going 106 miles per hour in that curve. the speed limit ahead of it would have been 80. but in the curve it was 106. what on earth could have been going on here?...
