Strange AI behaviour on Bristol to Exeter

[JamesC]

I have created a scenario using the new class 67 on a mail train on the Bristol to Exeter Route. The problem I am having is that some reason some AI trains are just stopping at signals even if the road ahead is clear. I usually would have this problem if the player train was crossing paths with the AI train put this is not the case. Anyone else been experiencing this problem?

Try putting extra waypoints in. I have noticed on Bristol to Exeter that the dispatcher will route down trains onto the up main line at Tiverton if left to its own devices. This also happens to trains coming off the Weston Super mare loop when travelling in the down direction. Try and finish all the AI at a portal. Double check all the paths and everything should run fine.
