Gauge One models are built to a scale of 10mm/foot, or approx 1:30 scale. This is a great scale for live steam locomotives, or electric and internal combustion models. This scale is often used in the great outdoors, however, indoor scenic layouts are not unknown.

A popular size especially in the garden, SM-32 models are built to a scale of 16mm/foot and run on a gauge of 32mm, the equivalent of a two foot gauge railway. SM-32 has become the first choice for many narrow gauge enthusiasts who want to operate live steam locomotives by radio control, the large size of the locomotives means plenty of room for the receiver and control servos. The SM-32 Streamline track system is compatible with the SM-32 Setrack system; the ST-607 Setrack curve is designed to match this turnout in order to create parallel sidings, run round loops etc.
