Welcome to the official website of the Gauge '3' Society. We are here to support and promote modelling in Gauge '3': Standard gauge scenic railways running on 2½ inch gauge track.


Amongst our membership we have collectors of vintage trains, those with high pressure live steam locomotives, garden railways with continuous circuits for fast steam running and those with smaller railways using 2-rail, battery or radio control. All are equally welcome in the Gauge 3 Society.
