Weirdness: If you have freight carriages, they change to passenger carriages when you change direction.
When you take over a train, if the train is moving when you suicide then the game will crash if the train makes it to another station.
Even after dying, I don't know how to give the AI control of the train again. I tried putting drivers in there and making it a DUMMY but once it gets taken by a player, only players can control it. I tried occupation DRIVER, maybe there is a more suitable occupation for the train but I didn't see one.
I didn't put CAR_BOMB in this example because for some reason vehicle weapons weren't appearing in the train even though they work in my full Loco script.
