The nominal size II (pronounced nominal size two) is in the standards of European Model Railroads (NEM) and the standards of the National Model Railroad Association ( NMRA ) standard size for model trains. Several occasions it is also known as nominal size 2. The meter gauge model with a track width of 1000 mm case has a model track width of 45 mm and is colloquially referred to as gauge IIm. The scale is 1:22.5.
According to the big space requirement the nominal size II has a distribution that should not be underestimated predominantly in the garden paths. Otherwise, it is little used. The best-known manufacturers in Germany are currently LGB, Piko, Trainline Garden Railways and Magnus model railway trade.
Some of the vehicles offered today for the gauge IIm represent compromises the scale of the model track since it increases either models of smaller gauges (750 mm or 760 mm model - gauge ) or reduce standard gauge vehicles.

The nominal size II, is rather less common due to the space required for a functioning system towards smaller scales in the model. Many model railroaders have to deal with the scale 1:22,5 organized in clubs / associations to pursue their hobby. The most well-known organization is probably the IG track II is an interesting annual AGM in Schenklengsfeld where driving is performed on modular layouts in all gauges, nominal size II. The dedicated model builder customize your vehicle and plant models for the most part itself, the basis of today's widespread use of narrow gauge railways has placed in the seventies, the LGB, which started a weatherproof meter gauge railway with a model track gauge of 45 mm in its production program. This track is designated in accordance with gauge IIm, LGB itself and other manufacturers use the term trace G. The G stands for garden or large car.
Since the early 1980s models are also available for the standard gauge model with a track width of 64 mm. Here the company Magnus has pioneered with consistent adherence of the scale 1:22,5.
For nominal size II European Model Railroads (NEM) are in scale 1:22,5 in the standards laid down the following model track gauge:
Model gauge of 64 mm (lane II)
Model gauge of 45 mm ( gauge IIm and Fn3 )
Several large series model railway and model railway accessories manufacturers put forth to each matching narrow-gauge track systems for standardized by the standards of European Model Railroads Track IIs. But since not exactly fit the resulting model gauge of 45 mm in each case to the respective model - gauges, there are different standards:
- For the models of narrow gauge railways on meter gauge the scale is 1:22.5 ( IIm track ) prevail.
- Are the standards of 1:20,3 ( Fn3 track or trace G) For the models of narrow gauge railways on 3 foot model - gauge; 1:22.5 (lane G) and 1:24 (lane G) according to the standards of the National Model Railroad Association shall prevail.
Not uncommon is the fact that gardening modelleisenbahn - capable vehicle models of the track I, which also have a model track width of 45 mm, together on plants, though hardly in the same train, with vehicles in the gauge IIm be used.
Because there are currently (as of 2009 ) in German speaking no large -scale manufacturers of vehicle models are, of narrow gauge railways manufactures in the track IIe, which correspond, for example, a model - gauge 750 mm according to the German or Austrian narrow gauge railways, the relevant vehicle models with really wrong track are produced. A typical example is represented by the Lehmann -Gross -Bahn ( LGB) produced locomotive models Stainz and U. In the original series, these operate on a model track width 760 mm. However, in the model the locomotives of a model that would operate on a model - gauge of 1,000 mm ( meter gauge ).
Model gauge of 32 mm (lane IIe )
In contrast to the German-speaking model gauge railways IIe in the UK are widespread. Here, this track is but otherwise Inscribed: Logically, translated into German is the expression of narrow gauge railways on track -0- tracks ( in 16 mm scale, 16 mm in the model = 1 foot in the prototype, 1 foot = 1 foot = 304.8 mm, corresponding to a notional scale of 1: 19,05 ). A not to be underestimated number of locomotives is operated with real steam. A related current manufacturer Mamod. One former manufacturer of track IIe toy trains in the German-speaking area were the brothers Faller.
Term nominal size II and nominal size 2
Originally, as now, the nominal size is designated by the Roman numeral II. According to the norms of European Model Railroads, the notation is with Roman numerals further preferred nominal sizes I and larger but may also be referred to in Arabic numerals.
Term nominal size F
The nominal size is F instead of nominal size II has American origin. She is then going to look for is that the Americans have their scale on the model track gauge of 45 mm converted and have assigned their own name for it, oddly enough, for the scale is slightly different. Internationally, the name of all currently standard nominal sizes is also consistent if, for example as in the nominal size 0 also different scales are common in different regions of the world. It can therefore be considered the exception to the rule. The letter F we also used for the description of the corresponding narrow-gauge railway model gauges. For example: Fn3.
Term G Scale
LGB itself and other manufacturers use the term G scale instead of the gauge IIm. This is company historically conditioned and has in it the origin, that the name of the trace G ( company name, company standard) does not meet the standards of European model railroaders NEM. The nominal size IIm denotes a narrow gauge railway. The track is standard gauge and narrow gauge G 45mm vehicles moving on the tracks with the track gauge. The manufacturers do not adhere to the 1:22.5 scale, but also offer models in the range 1:24 to 1: 29 for the G scale on.
