Mallard4468,
If you look closely at the track plan that I provided, you will see a Timesaver on the left and an Inglenook on the right. Theory of operations would be you build a train in the Inglenook, deliver it to the Timesave, return the empties to the Inglenook. The connection to the world provided by the car ferry would supply new rolling stock for the next cycle and retrieve the old, a mix of empties and loads from the island.
