In terms of model railway operation, gauge 3 is the largest (standard gauge) scenic railway modelling scale, using a scale of 13.5 mm to the foot. The Gauge '3' Society represents this aspect of 2 + 1 ⁄ 2-inch gauge railway modelling with both electric and live steam operation. Gauge '3' corresponds to NEM II scale, also known as "Spur II" in ...
Thus the scale and approximate prototype gauge are represented, with the model gauge used (9 mm for H0e gauge; 6.5 mm for H0f gauge) being implied. [ 2 ] The scales used include the general European modelling range of Z, N, TT, H0, 0 and also the large model engineering gauges of I to X, including 3 + 1 ⁄ 2 , 5, 7 + 1 ⁄ 4 and 10 + 1 ⁄ 4 ...
Track gauge conversion is the changing of one railway track gauge (the distance between the running rails) to another. In general, requirements depend on whether the conversion is from a wider gauge to a narrower gauge or vice versa, on how the rail vehicles can be modified to accommodate a track gauge conversion, and on whether the gauge conversion is manual or automated.
This scale is also popular in North America to depict 3 ft (914 mm) narrow-gauge prototypes (using dedicated 14.28 mm (0.562 in) gauge track and known as "Sn3"), and elsewhere to depict the 3 ft 6 in (1,067 mm) narrow-gauge railways (using H0 scale 16.5 mm / 0.65 in gauge track and known as "Sn3 1 ⁄ 2") of South Africa, Australia and New Zealand.

At present [when?] the choice of gauge is limited to two out of three of 1,435 mm (4 ft 8 + 1 ⁄ 2 in) and broad gauges 1,520 mm (4 ft 11 + 27 ⁄ 32 in) and 1,676 mm (5 ft 6 in). With narrow gauges such as 1,000 mm ( 3 ft 3 + 3 ⁄ 8 in ) as found at Zweisimmen , Switzerland, there is less room between the wheels for the gauge change ...
Comparison of 4 ft 8 + 1 ⁄ 2 in (1,435 mm) standard gauge (blue) and 3 ft 6 in (1,067 mm) (red) width; the difference is 14.5 in (370 mm), or about 26 per cent of standard gauge. 1,067 mm ( 3 ft 6 in ) between the inside of the rail heads, its name and classification vary worldwide and it has about 112,000 kilometres (70,000 mi) of track.
The TSI Rolling Stock (2002/735/EC) has taken over the UIC Gauges definitions defining Kinematic Gauges with a reference profile such that Gauges GA and GB have a height of 4.35 m (14 ft 3 in) (they differ in shape) with Gauge GC rising to 4.70 m (15 ft 5 in) allowing for a width of 3.08 m (10 ft 1 in) of the flat roof.
