In the return state, all trains are moved to a CCW figure-eight path in preparation for moving into the parking lot. The return state's function mirrors the function of the Transition state, migrating each train from their assigned path and direction to a CCW figure-eight.


As in the Transition state a CW figure-eight train, if present, can be changed to either a CW or CCW oval. Trains following an oval path can be changed to a CCW figure-eight following the rules defined earlier.


When all trains are following a CCW figure-eight path the simulator advances to the parking state (6).
