These are dependent on the directions of the inner or outer circle, e.g. the KHIC controller starts backwards because this is the only valid direction to travel this path. To drive a train from the Kicking Horse Station (facing forward) to the Inner Circle we have to combine the KHOC and OCIC controllers.
