G scale brings model railroading outdoors. Running on 45mm gauge track, these trains are designed to withstand weather and operate in garden settings. The large size makes them visible from a distance and easy for all ages to enjoy. Many G scale modelers create elaborate garden railways with real plants, water features, and weathered structures.
G scale was introduced by LGB (Lehmann Gross Bahn) of Germany in 1968. The scale was specifically designed for outdoor use, with robust construction and weather-resistant materials. 'G' originally stood for 'Garten' (German for garden) or 'Gross' (large).
