NEM gauges are arranged conveniently to use the normal gauge of smaller scales as narrow gauges for a certain scale. For instance, H0m gauge is the same as the TT-scale normal gauge, H0e same as the N-scale normal gauge and H0i same as the Z-scale normal gauge. For H0 and 0 scales, NEM uses the number zero, and NMRA uses letter "O" (HO instead ...
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.
Scale is the model's measurement as a proportion to the original, while gauge is the measurement between the rails. The size of engines depends on the scale and can vary from 700 mm (27.6 in) tall for the largest rideable live steam scales such as 1:4, down to matchbox size for the smallest: Z-scale (1:220) or T scale (1:450).
Railway modelling has long used a variety of scales and gauges to represent its models of real subjects. In most cases, gauge and scale are chosen together, so as to represent Stephenson standard gauge. By choosing a smaller gauge than this for a particular scale, the model represents a narrow-gauge example. [1] [2]

2 mm scale, often 2 mm finescale is a specification used for railway modelling, [1] largely for modelling British railway prototypes. [citation needed] It uses a scale of 2 mm on the model to 1 foot on the prototype, which scales out to 1:152. [1] The track gauge used to represent prototype standard gauge (4 feet 8 + 1 ⁄ 2 inches) is 9.42 mm ...
