G Scale Model Railroad


G Scale Model Railroad or large scale (45 mm or 1 3⁄4 inches, G gauge) is a scale for model railways, often used outdoors due to its size and durability. It is also referred to as the “Garden Scale” and is one of the largest commercially available scales in model railroading.


G scale was introduced by Ernst Paul Lehmann Patentwerk under the brand name LGB and was intended for indoor and outdoor use. Lehman Patentwerk, founded in 1881, started producing LGB in 1968. Märklin bought the remains of the company, and the production of certain items continues. The G name comes from the German word groß, meaning “big.” More recently, some people have come to interpret it as standing for “garden scale.”

The track scale soon attracted garden railway enthusiasts’ attention because of the robust and more reliable track. Coupled with products now available (or previously available) from more than 30 manufacturers around the world. G scale is seldom used indoors because of its size and the space required to track radii.

Though the term ‘G scale’ is used by many to refer to all models which run on a 45mm track. The same gauge as Gauge 1 – G scale refers more to LGB models. With a scale of either 1:22.5 or 1:24. Other terms are adopted for different scales used on a 45mm track. Such as Gauge 1 in the UK if modeling standard gauge.

If used with 1:22 scale trains, models of meter gauge railways can be created, popular in continental Europe. Any number of narrow gauge. The standard gauge models have been produced by manufacturers and enthusiasts to run on a 45mm gauge track. Three foot gauge-outline models with a scale of 1:20.3, or 15mm:1ft scale are known in the UK as ‘Fifteen Mil’, and internationally as FN3 – ‘F’ for scale, ‘N’ for narrow gauge and ‘3’ for the gauge.

In the UK, G scale is heavily supported by the G Scale Society and other narrow gauge modeling associations and regularly features in magazines such as Garden Rail.
