Your philosophy really makes no difference. In a bad wreck lives may be lost regardless of where people are on the train. Look at the Auto Train wreck, almost every passenger car hit the ground, and the ones that didn't were at the head end of the train. I know someone who was nearly buried alive in rocks in that wreck, and he was 7 or 8 cars deep in the train, where the sleepers would be in the new formation on the average train. The ultimate reality is that there is no safer way to travel than by train, and the folks who have the largest risk for losing their lives are the folks on the head end.
