HOn3 gauge represents the modelling of gauge railways in

HO scale 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. The rails are spaced apart for modelling standard gauge tracks and trains in HO. The ...

TT scale TT scale (from "table top") is a Rail transport modelling, model railroading scale at 1:120 scale with a track gauge of 12mm between the rails. It is placed between HO scale (1:87) and N scale (1:160). Its original purpose, as the name suggests ...

Most Japanese and Taiwanese HO scale models are made to run on 16.5mm gauge track and are made to 1:80 scale (Tomix, Kato and Tenshodo for Japan being the main brands and Haskell for Taiwan) but some small volume HOn3.5 kits and brass models are made for Japan with Imon being a major supplier.
