There is no way to be sure this method will work. Train drivers hit a couple people per year on average trying to ctb, and a former train driver has posted here before- he hit 14 people before quitting and 10 did ctb, for a 70% success rate- one that did ctb was in the hospital for four days before they died. Amputated limbs and brain inmuries, among many other injuries, including being paralyzed, happen for survivors. You have a 30% chance of a horrific outcome, too high for most people.
