Trains standing still

[Mr.Spissky]

If anyone here is playing Pak128.cz shud know that there is a demo world.  In that world the is some train that is always standing still on one location. Do anyone know how to make them do that?
Would be happy for an answer.

I don't know of this demo world, but you can make a train stand still at a station by telling it to wait for a full load at a station where it will never find anything to load. You can make trains stand still anywhere by creating a dead-lock, where one trains is waiting for another train to leave a section of track, and that other train is waiting for the first train to leave its section of track. Which makes this a rather strange question, because people usually come up with that last "solution" by accident themselves, and want to know how to get the trains to not stand still.
