In [[rail transport modelling]], '''Sn3½''' is a scale/gauge combination derived from [[S scale]] to represent [[narrow gauge]] {{RailGauge|3ft6in|lk=on}} track by using {{RailGauge|16.5mm}} gauge track (the same as [[HO gauge]]). The scale is [[1:64]].
Sn3½ is popular in [[South Africa]], [[Australia]] (particularly [[Western Australia]],<ref>{{cite web|url=http://amra-wa-branch.asn.au/index.htm|title=Australian Model Railway Association Western Australian Branch Inc|date=December 2012|accessdate=1 February 2013}}</ref> [[Queensland]]<ref>{{cite web|url=http://brisbanemodeltrainshow.com.au/wordpress/s-scale-modelling-group/|title=AMRA Queensland - S scale group|date=1 February 2013}}</ref> and [[Tasmania]]<ref>{{cite web|url=http://www.railtasmania.com/modelling/intro.php|title=Rail Tasmania - Modelling the Railway of Tasmania|date=12 October 2012|accessdate=1 February 2013}}</ref> where narrow gauge systems exist) and [[New Zealand]].<ref>{{cite web|url=http://nzmrg.org.nz/index.php?option=com_webpage&id=123|title=Modelling the railways of New Zealand|date=20 March 2013|accessdate=31 October 2022|publisher=[[New Zealand Model Railway Guild]]}}</ref>
Sn3½ is very rarely or never used for modelling in other countries with 3 foot 6 (1067mm) gauge railways such as in Japan, Taiwan, and Indonesia
== Track ==
As {{RailGauge|3ft6in}} track scales down to 16.5&nbsp;mm at 1:64, modelers use HO gauge track (which represents [[standard gauge]] at 1:87 scale) on Sn3½ layouts.<ref>{{cite web|url=http://nzrmodeling.webs.com/|title=Modeling the dream|work='S' Scale Modeling New Zealand Railway (NZR) | first = Grant | last = Morrell}}</ref>

Sn3½ is the primary scale for modeling New Zealand's [[Rail transport in New Zealand|narrow gauge 3&nbsp;ft 6 in railway]]s. 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 (HO gauge track) can either be purchased or hand laid with sleepers and rail. Alternatives for modeling New Zealand railways is [[TT scale|1:120]] or TT scale, known as [[NZ120]], as it is a cheaper option. [[HOn3½ gauge]], HO scale with 12mm gauge, is also increasing in popularity.
