The Runaround command issued to drivers is able to switch all of the junctions at St Nicolaas Yard, Westside, Fogarty's End, Smallbrook, Oyonix, Rosario Transport and at Daydream Mine and the power station. (Eventually! You need to be patient as the AI driver works it out in their tiny animated heads...) :wave:
You can greatly assist AI drivers by adding additional track marks in the St Nicolaas yard as navigation waypoints or destination points. They will switch any junctions necessary on the way to complete their task list..
