N Scale
Model railroads come in many sizes, and at the BBM Group we specialize in N Scale, with a track gauge of Nine millimetres.
The second most popular size in model rail today, "N" trains run on track with a gauge of 9mm, available from many vendors in ready-to-run and customizable form.
However, strangely enough, around the world there are three different sizes or scales in use for "N" gauge! In the USA and related markets,
and in most of Europe, the scale is 1 to 160, while in Japan they adopted 1 to 152, and in the UK it is 1 to 148.
