Note that it does not confuse the scale (scale in English) which means the reduction ratio relative

the real hardware (which is expressed as 1 / x) and the trade name "scale" (gauge in English)

which designatesown stock to run on a track of a given écatement (HO, 0, N ......)

For example the G and 1 use the same track but with totally different scales. (1/22.5 for LGB and

1/32 to the actual 1)
