G scale


In railway modelling, G scale or G gauge, also called large scale, is a track gauge which is often used for outdoor garden railways because of its size and durability. G scale trains use a fixed track gauge of to accommodate a range of rail transport modelling scales between narrow gauge, metre gauge, Playmobil trains, and standard gauge.
G-scale LGB was introduced in 1968 by Ernst Paul Lehmann Patentwerk in Germany. LGB products were intended for indoor and outdoor use, so the "G" became interpreted as "garden scale".
Most track is made of brass which can remain outside in all weather. Track can also be obtained in less expensive aluminium as well as oxidation-resistant, though more expensive, stainless steel.
Like other scales, large scale is sometimes used for model trains that run indoors on a track mounted against the wall near the ceiling.

G scale versus G gauge

G gauge track has a spacing of 45 mm between the rails, adopted from the pre-existing Gauge 1, but that does not determine the scale to which the models are built because, to maintain a constant track width when real-life counterparts have a variety of railroad gauges, the scale has to vary. The most common full-scale practice uses a spacing of, whereas some narrow-gauge railways have rails apart or less. Although often built with standard-sized doors, a narrow-gauge train is in most other respects smaller than its standard-gauge counterpart: its cars are generally narrower and shorter, allowing them to navigate more sharply curved and lightly built tracks.
Model trains are built to represent a real train of standard or narrow gauge. For example, HO scale models all use 16.5 mm gauge track to represent standard gauge trains while a narrower-gauge track such as 9 mm N gauge is used to represent real narrow gauge.
G model railways depart from this and always use the same gauge with the trains instead built in different sizes depending on whether they are intended to represent standard-gauge or narrow-gauge trains. Because of this it might be more correct to speak of "G gauge" rather than "G scale" since the consistent aspect is the gauge,, but the term "G scale" is used when 1:22.5 is used.
The 45 mm gauge originated from 1 gauge or "gauge one" which was first used in Europe and Britain and used to model standard gauge trains in the scale of 1:32.
LGB were first to adopt the term G scale and used the gauge of to model 1,000 mm gauge European trains in 1:22.5 scale.

Scales that run on G gauge track

  • 1 gauge: 1:32. Used to model standard gauge trains of gauge.
  • 1:29 scale or A scale: 1:29. First used by Aristo-Craft to model standard-gauge prototypes. Incorrect scale/gauge but proportionally similar to other popular brands of the time.
  • G scale: 1:22.5. Used to model European trains that run on metre gauge track. This scale-gauge combination is called "scale IIm" according to NEM 010. The G comes from the German word groß meaning "big".
  • H scale -inch-to-the-foot, or 1:24 scale. Used to model gauge or "Cape gauge". Incorrect scale used for 3 ft gauge track.
  • F scale 15 mm-to-the-foot scale,. Correct scale/gauge typically used to model North American narrow gauge trains on gauge track.
  • Seven eighths: -inch-to-the-foot scale. Used to model trains on narrow gauge track.
  • 16 mm scale: 16 mm-to-the-foot. Originally intended for modelling 2-ft gauge prototype railways on 32 mm track. The models are often re-gauged to also run on 45 mm track. This scale has also been used to model gauge prototype trains.

    Manufacturers

  • Accucraft has five scales: Fn3 at 1:20.3, gauge 1 at 1:32, -inch scale at 1:24. They also build 1:29-scale North American models in live steam and electric under the AML brand, as well as British live steam and electric models in 1:19 scale and Isle of Man live steam and electric models in 1:20.3 scale. The Isle of Man scale uses three-foot gauge track, the same width as the dominant U.S. Colorado narrow gauge.
