G scale trains commonly run on 45mm gauge track. Outdoor railroads often use broad curves, long straight sections, switches, bridges, tunnels, sidings, and raised track areas to create routes that blend into a garden or backyard landscape.
When choosing G scale track, consider the minimum curve required by your locomotives and rolling stock, the available layout space, the track material, and the amount of maintenance expected. Larger locomotives and passenger cars often need broader curves than compact starter-set equipment.
G scale trains may use traditional track power, onboard battery power, or radio control. Track-powered layouts receive electricity through the rails, while battery-powered locomotives carry their power source onboard.
Battery operation can reduce electrical problems caused by dirty or weather-exposed rails, which makes it popular for outdoor railways. The right system depends on the locomotive, layout size, maintenance preferences, sound features, and the type of control the operator wants.
Large-scale trains can share the same 45mm track gauge without representing the same scale. G scale is commonly associated with approximately 1:22.5 proportions, especially for European narrow-gauge trains. Gauge 1 is generally 1:32, while F scale is commonly 1:20.3 for North American 3-foot narrow-gauge railroads.
Because these trains can use the same gauge of track, some hobbyists operate multiple proportions together. However, the differences may be noticeable when locomotives, rolling stock, figures, vehicles, and structures are placed side by side.
Pre-owned G scale trains give buyers access to discontinued brands, retired models, limited-production releases, older road names, and equipment that may no longer appear in current manufacturer catalogs. Aristo-Craft and certain older LGB models remain especially popular with large-scale collectors and operators.
Trainz inventory may include used G scale locomotives, rolling stock, train sets, track, buildings, accessories, parts, original boxes, and new old stock items. Availability changes as private collections, estate purchases, and trade-ins arrive.

G scale commonly refers to large-scale trains that run on 45mm gauge track. While many G scale models are produced in 1:22.5 scale, the term also includes other proportions such as 1:24 and 1:29. F scale is 1:20.3 and models North American 3-foot narrow-gauge railroads. Both use 45mm gauge track, but F scale equipment is generally larger.
Gauge 1 trains also use 45mm gauge track but are built to approximately 1:32 scale for standard-gauge railroads. G scale models are generally larger because many represent narrow-gauge prototypes.
