How do you derail a train without colliding without another train?
You could turn on switch at maximum speed :)
Hit buffers lol
Well, if you're saying to derail an AI train without hitting them, it would be really difficult to.
It is possible. By giving them the right amount of waiting, it is possible to make them go impatient and crash with other AIs. Don't try though, it leads to more crashes and then the thing that will crash is game.
