Sometimes it works

[BlueLight]

While creating a new scenario for the Cajon Pass I am constantly running into the problem of A.I. having a mind of its own. As I run the scenario, sometime the A.I. trains move as programed. Other times they do not move at all and in this case that particular train locks the switch so you cannot proceed. Has anyone else had this type of problem and if so, how did you correct it?
