Marbelup Models offers a range of models based on narrow gauge locomotives and rolling stock of the Western Australian Government Railways (WAGR). The models are in Sn3½ scale which is 1:64 scale, running on 16.5 mm gauge track to correctly represent the narrow gauge look of the prototype which is 1067 mm (3ft 6in) gauge. Please note that because the Prime Gray material is quite new, the long term durability and stability of models made from it are not known. These models will not be available for sale through the i.Materialise Shop, but they are available for sale direct from Marbelup Models. Visit the Marbelup Models web site for information on price and availability.
