Model Locomotives
Scales, components and other nuances.
To make a model of a railway, you need to understand many nuances, for example, on what scale a miniature railway is usually carried out, what kind of sets and configurations of crafts can turn out, whether a scheme is needed and where to get it, how to deal with components, necessary parts and various accessories, etc.

Standards of scales and sizes for railway modeling are very different. The most common are standard sizes bearing the symbol TT and NO.
The TT standard size - from the English Table-top trains - means that the layout of the railway is carried out on a scale of one to one hundred and twenty (1:120) with a gauge of twelve millimeters. Such a railway in miniature is also called a twelve-millimeter. Also, all mobile models of trains are made in it – this is done by bringing electricity along the rails, although it is possible to connect an electric locomotive through the contact network.
A large number of models and various accessories for assembling railway miniatures of this standard size are produced by:
German companies Berliner TT Bahnen, Tillig;
European manufacturers Roco and Piko have a small choice;
Jago company pleases fans with rare models of vintage locomotives;
American PossumValleyModels, GoldCoast (some models of wagons and locomotives).
Another common standard size is NO. The name comes from the English abbreviation HalfZero or half zero. The layout of the railway in this case is made in a scale ratio of one to eighty-seven (1:87). There is also a standard size 0, in which the scale is taken twice as large, that is, 1 to 45. And here it turns out half of zero, but the Latin letter O is used instead in the designation.
