having trouble with ai trains

[denmit]

hello i have a train that is scheduled to drive to a track marker it has stops at two other track markers along the way the first to it stops and waits at like it should but when i get to the third it just keeps on heading down the track..
before it gets to the third track marker an exception comes up and says invalid direction request when going past a switch on the way there I have tried redoing the switch a couple of times making sure all the track went the same way and the switch lever was in the right position and working . any help would be great thanks in advance

I've never seen that message, but I wonder do you have any direction markers there facing the wrong direction? I do know that Auran has added more deailed dialog messages so perhaps this is one of them.

If the markers are the problem, this will prevent the AI trains from reaching their destination directly, and sometimes will force them to backup or do other weird things trying to get to the track mark. I had this happen once or twice when I've selected an incorrect trackmark that was on the opposite platform of a station. I wanted the eastbound platform, but chose the westbound. The AI driver went crazy, backing up and doing all kinds of switching moves to get to the destination.
