'''Gauge 2''' (also called '''2 gauge''' or '''II gauge''') is a [[model railway]] [[Rail gauge|gauge]], originally {{RailGauge|64mm}},<ref name="NEM010">{{cite web|url=http://www.miba.de/morop/nem010_d.pdf|publisher=[[Normen Europäischer Modellbahnen|NEM]]|title=Normen Europäischer Modellbahnen Maßstäbe, Nenngrößen, Spurweiten|language=German|date=2011|accessdate=2014-05-15|archive-date=2016-03-03|archive-url=https://web.archive.org/web/20160303174618/http://www.miba.de/morop/nem010_d.pdf|url-status=dead}}</ref> then standardised in 1909 at {{RailGauge|2in|first=imp}}, a 20% reduction and a change in definition: from mm to inch.{{citation needed|date=February 2016}} It has since fallen into disuse. The gauge was introduced by [[Märklin]] at the [[Leipzig]] [[:de:Leipziger_Messe#modell-hobby-spiel|toy fair]] in 1891. Gauge 2 was equivalent to a 1:22.5 scale.<br />
<br />
==Related scales and gauges==<br />
After the change to {{RailGauge|2in}} in 1909, {{RailGauge|64mm}} gauge was standardised as [[3 gauge]] (or ''III gauge'').<br />
<br />
European [[G gauge]] trains are built to the same II gauge scale, but with a narrow rail gauge of {{RailGauge|45mm}} (the same as [[1 gauge]]). This G gauge at 1:22.5 scale represents {{RailGauge|1000mm|allk=on}} [[narrow-gauge railway]]s. This scale-gauge combination is sometimes called '''IIm''' in European literature.<br />
<br />
In the [[United Kingdom|UK]], Gauge 2 was 2 inches (50.8 mm) while Gauge 3 was {{RailGauge|2.5in}}. From this, it follows that [[G gauge]] is sometimes, albeit rarely, referred to as 3m. A 2 inch (50.8 mm) gauge of standard gauge locos gives a scale of 1:28.25, not so far off the 1/29 used by some manufactures with {{RailGauge|45mm}} gauge track. In the grand tradition of model rail gauges often being narrower than the full scale equivalent ([[00 scale]] being the classic example) this is deemed perfectly acceptable.<br />
