At the time this great hobby started, they didn't have the modern communication systems we have today, but they had plenty of goodwill. The toy manufacturer of the nineteenth century followed the same pattern of the real railways by manufacturing their toy trains with different scales as the actual railway trains themselves had different dimensions. The actual gauge dimensions in- France measures 60 cm, the British track measures four feet eight and a half inches (1.435 m) in Spain the gauge is 1.676 m and in Russia 1.524 m. So many dimensions and so many complications! To try to see clearly, know that there are about fifteen different spacing between the railway channels but not all are measured the same way. Some are measured between the axes of the rails and other are measured between the inside faces of the rails. It is true that the railway scales are directly proportional to the size of engines, locomotives and wagons.

Model railway scales

The words railway scales and gauges seem at first interchangeable but their meanings are different. Scale is the model's measurement as a proportion to the original, while gauge is the measurement between the rails. At first, model railways were properly scaled. Manufacturers and hobbyists soon arrived at the fact that they need standards for interchange ability, such as gauge, but trains were only a rough approximation to the real thing. Official railway scale for the gauges were drawn up but not correctly proportioned for the gauge chosen. O (zero) gauge trains, for instance, operate on track too widely spaced in the United States as the scale is accepted as 1:48 whereas in Britain O gauge uses a ratio of 43.5:1 or 7 mm/1 foot and the gauge is near to correct. British OO standards operate on track significantly too narrow. Railway Scale modeling could be a very easy task if we use the same manufacturing facilities for all our needs from track, locomotives or scenery.

In Model Railway, the HO scale or (half-O) 3.5 mm/1 foot or 1:87 is the most popular model and the most common model railroad scale, with models 1/87 scale the size of the real trains. N scale models are 1/160 scale, or 1/160 the size of a real train, S scale is 1/64, and G scales models are 1/32, 1/29, 1/24, 1/22.5, or 1/20.3 scale, depending on the manufacturer. To enjoy modeling throw the years, you need to decide first on the scale of your choice for your exciting hobby.
