Discussed several times. The tl;dr is that fatalism is deeply embedded into their culture, almost at a genetic level. If they weren't meant to be hit, then they wouldn't have been hit. There's no point trying to avoid being hit by a train, because if the gods want you to be hit, you'll be hit, and if they don't, it'll just not happen. And if it does happen, you just start over. It's a hard concept for westerners to grasp, because our culture is built on the presumption that a man can determine his own destiny, to some greater or lesser degree, and that this life is the only life we get. The closest we have to that sort of fatalism is calvinism, but even an extreme calvinist wouldn't just stand in front of a train and declare it god's will if he lives or dies.
