Scale/gauge: 16mm scale, 32mm & 45mm gauge
Motive power: Live steam & battery

Mwch Grumblyn is a dual 32 and 45mm gauge system from the Guildford Model Engineering Society, mainly steam powered together with some coal fired locomotives to enjoy. It is over 20 years old and a favourite on the exhibition circuit. It is probably unique in being a rhomboid shape and measures 9 by 6 metres. The group has a really diverse taste in rolling stock, which can be freelance or prototypical, featuring both UK and continental prototypes. Being part of a model engineering society, members are very skilled scratch-built modellers who like to spread their expertise and knowledge, especially to newcomers.
