I don't knwo if that would work to try to time that to go under one of the freight carsas it passes, I am pretty sure the train goes way too fast compared to a person's top speed for this to work- it's an interesting idea, but I doubt if it would work. The biggest risk with a train attempt is the 1 in 3 chance of survival, often with amputated limbs, brain damage, etc- a train is one of the worst methods to survive and a 1 in 3 chance of survival, which is a creedible estimate based on a precvioius post from a former train driver, is way too high of a risk for such horrible reslts. Even of the people who die records show they may spend up to four days in the hospityal in extreme agony before they die- the downside risk is way too high for me iwth this method.
