I am trying to straighten out a problem in one of the TS12 default sessions Norfolk and Western Coal Session. The AI trains that approach a junction, if the junction is set incorrectly, will just sit there forever, rather than changing the junction. Now I notice in the session rules there is a set junction command and these are usually located after a trigger check. What I want is for the AI to be able to control the junction, when they AI approaches it rather than just sitting there forever because the junction is toggled the wrong way. One of the options in the set junction, is to enable AI control. If I do that for a particular junction, is that the best way to allow the AI train to toggle that junction, when it arrives, so it can pass ( providing the track it will be switched to is clear).
