Gauge 2 (also called 2 gauge or II gauge) is a model railway gauge, originally Template:RailGauge,[1] then standardised in 1909 at Template:RailGauge, a 20% reduction and a change in definition: from mm to inch.Script error: No such module "Unsubst". It has since fallen into disuse. The gauge was introduced by Märklin at the Leipzig toy fair in 1891. Gauge 2 was equivalent to a 1:22.5 scale.
Related scales and gauges
After the change to Template:RailGauge in 1909, Template:RailGauge gauge was standardised as 3 gauge (or III gauge).
European G gauge trains are built to the same II gauge scale, but with a narrow rail gauge of Template:RailGauge (the same as 1 gauge). This G gauge at 1:22.5 scale represents Template:RailGauge narrow-gauge railways. This scale-gauge combination is sometimes called IIm in European literature.
In the UK, Gauge 2 was 2 inches (50.8 mm) while Gauge 3 was Template:RailGauge. 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 Template:RailGauge 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.
