2. Live steam - Wikipedia

   en.wikipedia.org/wiki/Live_steam

   For instance, scales of 1.5, 1.6, 2.5, and 3 inches per foot (corresponding to scales of 1:8 to 1:4) have been used on a 7 + 1 ⁄ 2 in (190.5 mm) track gauge. The generally accepted smallest gauge for a live steam locomotive is O scale. Producing smaller-scale models remains problematic, as the laws of physics do not themselves scale: creating ...

   This scale is today the most popular modelling scale in the UK, although it once had some following in the US (on 19 mm / 0.748 in gauge track) before World War II. 00 or "Double-Oh", together with EM gauge and P4 standards are all to 4 mm scale as the scale is the same, but the track standards are incompatible. 00 uses the same track as HO (16 ...

   The next largest scale range, G scale (1:22.5) in the US and 16 mm scale (1:19.05) in the UK, and as large as 1:12 scale, is too small for riding but is used for outdoor garden railways, which allow use of natural landscaping. G scale is also sometimes used indoors, with the track mounted adjacent to walls at eye level of standing adults.
