The different model train scales

Model trains are produced in a variety of gauges, ranging from 1:8 for the biggest to 1:220 for the smallest. These different scales have their own strenght and weaknesses and modelers have interest for either one in their hobby time. Up to 3 meter long models represent the biggest scale while the smallest accounts for models no longer than a few centimeters. The H0 scale (1:87) is the most popular followed by the N (1:160).

Like real life railroads, the different scales are specific to track gauges in line with track spread.

(N) : Scale 1:160 (9 mm track gauge), the second most popular in model railroad fans. This scale railway material is much less abundant.scale. However, it attrack more and more fans and manufacturers produce increased quantities of models. Although more popular in Europe, it attracks many north american enthusiasts.

(O) : Scale 1:48 brings together many United States fans. They seem to favor operating trains over modelism per se. Many among them are old items collectors. Recent changes in this scale increased its popularity with model railroad amateurs.

(G) : Scale 1:20 (45 mm track gauge), also named Garden, better fits outside networks. This scale is favored by modelists preferring bigger and more robust rolling stock of garden networks.

(7-1/4 Live Steam scale) : This scale, very popular in both Canada and United States, better fits large outdoor networks on which modelers can sit on the rolling stock. Experienced modelers build these.
