this would be so cool. and in city rp, you could allow criminals to rob a train, by taking control of it and possibly ejecting players, or killing them and taking their money. (i don't now if that would be possible in blockland but it would be worth a try)
p.s the tying people to the train tracks could be a job for a new career. madmen/murder/kidnappers
you could also tie people up in front of planes that are landing, or with taxi's you could lock doors when people get in and force them to pay to get out, or just kill them and take their money
