G scale“Gauge” is the distance between two rails: for LGB track this is distance
G scale is not a official term used from American and European railmodel association, but simply a marketing concept introduced by LGB in 1968. LGB pioneered garden scale model trains so originally they had the most products. In garden rail we have four major scales, all running on the same gauge (
45 mm). LGB is the largest, then comes 1:24, 1:29 scale and 1:32 scale. The manufacturers tried to make their products compatible with LGB's so we would use together on the same track, building models to a slightly smaller scale than LGB. Even though LGB changes the proportions of its American prototype models. That is where the trouble began!
This could be a great problem, but in garden rail most of people prefer run their “G scale” model adopting a compromise, playing with gauge discrepancies as long as the scale of the trains remains consistent. When we run our G scale train outside in the garden we are more interested in general impression of layout than in each little detail of train models. Visitor are usually impressed by long trains, but also by landscape, building, accessories … This is G scale and garden rail philosophy.
