7mm Narrow Gauge Association

British railway modelling society

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).

## Scope of interest[edit]

The association covers modelling British narrow-gauge railways in the following gauges:

* O16.5. O scale on 16.5mm track, representing 2 ft 41⁄4 in gauge. This scale is widely used to model railways of 2 ft (610 mm), 2 ft 3 in (686 mm) and 2 ft 6 in (762 mm) gauges.[1] 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 2 ft (610 mm) gauge prototypes.[1]
* O21 Fine scale modelling of 3 ft (914 mm) gauge prototypes on 21mm gauge track.[1]
* O9 Using 9mm or N gauge track to represent amusement park and estate railways.[1]

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.[2] 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.

## History[edit]

The association was founded in 1979.[1]

## Membership[edit]

The current membership of the association is around of 900 members. Most are resident in the United Kingdom, but about 10% live overseas. The association has 6 local groups in different areas of Britain, and two groups based outside Britain.[2]

## Publications[edit]

The association publishes a bi-monthly magazine, Narrow Lines, which is posted free to all members. Additionally, the association has published a series of 5 handbooks on various aspects of modelling, and a series of 12 booklets containing scale drawings of various items of narrow-gauge rolling stock.
