Ridable, outdoor gauge, named according to the gauge in inches, and scale in inches per foot, for example 7 + 1 ⁄ 4 in (184 mm) gauge, 1.5 inch scale. The gauge is 7 + 1 ⁄ 2 in (190.5 mm) in the US and Canada, where the scale sometimes is 1.6 inch for diesel-type models. Private and public (club) tracks exist in many areas.
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 ...
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]
Ten and a quarter inch gauge (or X scale) (10 + 1 ⁄ 4 in / 260 mm) is a large modelling scale, generally only used for ridable miniature railways. Model railways at this scale normally confine the scale modelling aspects to the reproduction of the locomotive and with steam locomotives the accompanying tender .
1:29 G scale boxcar by Aristo-Craft on G gauge track 1:32 scale 2-bay offset hopper by Mainline America. G scale or G gauge, also called large scale (45 mm or 1 + 3 ⁄ 4 inches), is a track gauge for model railways which is often used for outdoor garden railways because of its size and durability.
The terms "scale" and "gauge" are often confused. Strictly speaking, scale is the ratio of the size of a model to that of its prototype and gauge is the distance between the track railheads. In the case of S scale, the proportion is 1:64 or 3 ⁄ 16 inch modeling 1 foot. Standard S gauge track has a spacing of 7 ⁄ 8 inch (22 mm).
HO or H0 is a rail transport modelling scale using a 1:87 scale (3.5 mm to 1 foot). It is the most popular scale of model railway in the world. [1] [2] The rails are spaced 16.5 millimetres (0.650 in) apart for modelling 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge tracks and trains in HO.
