The first layout we built was known as South Pacific Lines and was in the basement in HO. Demolished: too cold and lonely. We have since moved.
Now we use South Pacific Lines to refer to our whole family of layouts (because the name and logo were too cool to abandon), including that original one and the following:
Jack's layout in N scale, slung inside a wardrobe and marginally portable. Gave it away when we moved.
Port Bonifacio in HO in a bedroom. Heart-breakingly demolished when we moved, as I had to give up HO entirely - no room in the new house.
Wettington and Mahawatu Rwy Version 1 in the garden in G scale. Even more heartbreakingly demolished when we moved, as the official opening and the last run were on the same day.
Wettington and Mahawatu Rwy Version 2 rises again in the new garden.
