The 3mm Society was formed over 40 years ago to support 3mm: 1ft railway modelling. In the early days much 3mm modelling was based on Triang TT3 locos and rolling stock and GEM and Bec kits, but the Society was quick to develop finer standards and to promote more advanced modelling. Over the years the Society has encouraged independent traders to support 3mm scale, but has also produced its own huge range of items such loco and rolling-stock wheels, loco, coach, and wagon kits, track components and a large range of accessories and scenic items. For the many members who still run vintage Triang stock the Society offers support services and recycles second-hand items at sensible prices.
The 3mm Society is a scale society, not a gauge society. Its members model in various gauges including 12mm (the original TT gauge), 13.5 and 14.2mm fine-scale standard gauge, 15.75mm (Irish) and 6.5 and 9mm narrow gauges. All 3mm modellers, whether fine-scale scratchbuilders, kitbuilders or those maintaining a classic Triang system, coexist happily in The 3mm Society.
