Sn3½


In rail transport modelling, Sn3½ is a scale/gauge combination derived from S scale to represent narrow gauge track by using gauge track. The scale is.
Sn3½ is popular in South Africa, Australia and New Zealand.

Track

As track scales down to 16.5mm at 1:64, modelers use HO gauge track on Sn3½ layouts.

New Zealand

Sn3½ is the primary scale for modeling New Zealand's narrow gauge 3 ft 6 in railways. The majority of rolling stock available, are white-metal kits, making them considerably more expensive and heavier than other scales and countries. Many of these kits are highly detailed. Buildings are generally hand-made and track can either be purchased or hand laid with sleepers and rail. Another alternative for modeling New Zealand Railways is 1:120 or TT scale, as it is a cheaper option.

Sm gauge is also defined by the German NEM 10 standard, representing Continental European metre gauge.
