Problem with trains.

[Ilari on homo]

Hello. I would like to make AI controlled trains use waypoints.
I think it is not as simple as making other things move.
I know how to make waypoints work but with trains i failed and the train refuses to move. If there are any ways to get the train moving when AI controls it, i would like to know. Waypoints or any other crap like that i don't care.
I already know how to make player controlled trains move manually.
Does it require some kind of special waypoints or something else?
