No one dies, because we can demonstrate that the track is infinitely empty by moving the person in the first position to the second position (and second to third and so on) before the trolley hits them. Then just repeat the process before the trolley reaches the second position (and so on).
It also says nothing about scale. It could be that to get to the first integer it could take one second or until the heat death of the universe. The reals however are immune to your and my trick
