What Is an N Scale Model?

An N scale model is a size of model train that uses 9 mm or 0.354 inch track gauge. N scale models are sized between 1:148 to 1:160 of their real-life counterparts. The term N scale model is also used to describe other types of models that are within the same size range. When speaking of model trains, the terms "N scale" and "N gauge" are generally interchangeable. Several variants of the N scale model train have been released.

Model Trains
- Model railroading is a hobby in which railway locomotives, cars and tracks are modelled on a reduced scale. Their sizes are measured by the ratio of the model&'s size to the actual locomotive or car&'s size. The model track size or gauge is generally measured in millimeters.
  
  The first electric model trains were released near the beginning of the 20th century and bore only a crude resemblance to the trains they were based on. Train models have since become extremely close imitations of actual trains.
History
- The first commercially produced N scale model train set was released in 1962 by the Arnold company of Nuremburg. At the time, standards for manufacturing model trains were practically nonexistent, but within two years of the N scale model&'s release, standards had been set for track gauge, voltage and car linkages. Arnold allowed other manufacturers to use its "Rapido" coupler on their models, which allowed hobbyists to craft trains from models produced by different manufacturers.
Popularity
- N scale is used worldwide and is second in popularity only to HO scale, a slightly larger format. N scale is Japan&'s most popular format, as its smaller size does not take up scarce space inside homes. Its smaller format also appeals to hobbyists who wish to create more expansive sets.
Japanese N Scale
- Japanese N scale combines 9 mm gauge track with models on a 1:150 scale, which are slightly larger than most models set on 9 mm track. The relative sizes of the larger train models to the smaller track is meant to simulate the narrowness of train tracks in Japan. Models much larger than this do not sit well on the 9 mm track.
The 2 mm Scale
- N scale track can also be used with 2 mm scale models that are popular in the United Kingdom. The 2 mm scale models have a 1:152 scale, or 2 mm to a foot. The 2 mm scale models are designed to ride a 9.42 mm or 0.371 inch track gauge. Many hobbyists prefer the appearance of the 9 mm N scale track, saying it looks closer to scale appearance than the larger gauge.
