7mm Narrow Gauge Association
Encyclopedia
The 7mm Narrow Gauge Association is a United Kingdom
based society for railway modellers
interested in modelling narrow gauge railways in British O scale
(7mm to the foot, or 1:43.5 ratio).
However other gauges and O scales are also accepted. For instance members modelling American narrow gauge often use On30
, and Oe
when modelling European prototypes. While many members model British railways, prototypes from all round the world are catered for, including the railways of countries that were part of Britain's former empire

interested in modelling narrow gauge railways in British O scale
O scale
O scale is a scale commonly used for toy trains and model railroading. Originally introduced by German toy manufacturer Märklin around 1900, by the 1930s three-rail alternating current O gauge was the most common model railroad scale in the United States and remained so until the early 1960s...

Scope of interest
The Association covers modelling British narrow gauge railways in the following gauges:- O16.5On30On30 is the most common term used to describe the modelling of narrow gauge railways in O scale on HO gauge track. Other terms used include O16.5, Oe, and On2½. It is part of the hobby of rail transport modelling.- Definitions :...
. O scale on 16.5mm track, representing 2 ft 4¼ in gauge. This scale is widely used to model railways of , and gauges. The use of a 16.5mm gauge allows the use of 00 gauge mechanisms and wheels. Most commercial equipment is available for this gauge. - O14 Using 14mm gauge track giving an exact scale conversion for gauge prototypes.
- O21 Fine scale modelling of gauge prototypes on 21mm gauge track.
- O9 Using 9mm or NN scaleN scale is a popular model railway scale/track gauge. Depending upon the manufacturer , the scale ranges from 1:148 to 1:160. In all cases, the gauge is . The term N gauge refers to the track dimensions, but in the UK in particular N gauge refers to a 1:148 scale with track gauge modelling...

The British Empire comprised the dominions, colonies, protectorates, mandates and other territories ruled or administered by the United Kingdom. It originated with the overseas colonies and trading posts established by England in the late 16th and early 17th centuries. At its height, it was the...
