G Gauge & Garden Railways

G Gauge & Garden Railways

G Gauge (1:22.5 scale, running on 45mm track) is the largest commonly available model railway scale — and the only one truly designed for outdoor use. Garden railways combine the joy of model trains with the pleasure of being outdoors, and the large scale means impressive detail and robust construction.

LGB (Lehmann Gross Bahn) pioneered the garden railway concept and remains the benchmark for quality and weather resistance. PIKO offers an extensive and more affordable G Scale range covering European and American prototypes, while Bachmann produces garden-scale models primarily for the US market.

G Gauge track is designed to withstand the elements — UV-resistant rail and weatherproof points mean your railway can stay outdoors year-round. The large size also makes G Gauge a favourite for families, exhibitions and garden centre displays.
