From Wikipedia, the free encyclopaedia
G scale is a scale for model railways, and because of its size and durability, G
scale is often used outdoors. Such installations are known as garden railways.
G scale was introduced by Ernst Paul Lehman Patentwerk under their brand name of
LGB, meant for indoor/outdoor use. Lehman is the major European manufacturer of
G scale trains, and considered the one that really made garden railways popular.
Their trains are sold as the Lehmann Gross Bahn (or "Lehmann Big Train"). Lehman
Patentwerk was founded in 1881 and started producing LGB in 1968. Today it
produces models of European and US originals, of steam, diesel and electric
prototypes as well as a large range of coaches, trucks and accessories.
The term "scale" is a misnomer, as the actual scale of the trains that run on it
vary from system to system, country to country. G scale is more correctly called
"G Gauge", as the gauge of the track is the one consistency.
The name comes from the German groß (meaning "big"). Traditionally, G scale is
the use of 45 mm gauge track, as used for standard gauge (Gauge 1) models, for
modelling metre gauge narrow gauge railways, using the correct scale of 1:22.5.
Metre gauge is the most common narrow gauge in Europe.
In the United States, the commonly used narrow gauge is 3 feet; modelling this
correctly with a 45 mm track gauge gives a scale of 1:20.3, which is commonly
used by American manufacturers. In actuality, these are called G Scale, even
though in reality they are not. Some modellers and train producers call 1:20.3
"F scale".
Other scales are used to model other narrow gauges.
Gn15 modellers use 1:24 scale parts and details along with HO/OO scale track
(16.5 mm gauge) to model 15 inch gauge railroads, otherwise known as minimum
gauge.
Although some call models of standard gauge equipment to 45 mm track gauge 'G
scale', these models are more correctly referred to as Gauge 1, I Scale (NEM
Standard 010), or 3/8" scale (NMRA S-1).
LGB and several other manufacturers produce track made of brass which can remain
outside in all weathers – a quick wipe and it is ready for use. Track can also
be obtained in less expensive aluminium as well as oxidation-resistant, though
more expensive, stainless steel.
