Collection: HOn3 Scale

This is one of the narrow gauge scales, often used in mountainous regions in real life to be able to negotiate sharp curves. In the modeling world, the designation refers to HO sized locomotives and railcars running on N scale track. Originally, the tracks had to be handlaid for customization of the measurements and the locos and railcars had to be scratchbuilt for the same reason. Now companies like Bachmann are manufacturing HOn3 equipment so you don't have to scratchbuild them.
