2 mm scale is a scale used for railway modelling, largely of British subjects. It uses a scale of 2 mm on the model to 1 foot on the prototype, which scales out to 1:152. It is, therefore, similar in size to the slightly larger British N scale at 1:148 and the slightly smaller European/American N scale at 1:160; it predates both versions of N scale. The track gauge used is 9.42 mm, wider than commercial N scale. Track and wheels are exact scale replicas of those on real railways; the track is only 1 mm high. This article needs cleanup. ... U.S. Prototype model of an N scale (1:160) Chesapeake and Ohio Railway 2-6-6-2 shown with a pencil for size N scale (or sometimes N gauge) is a popular model railway size, allowing hobbyists to build layouts that take up less space than HO scale, or... Rail gauge is the distance between the inner sides of the two parallel rails that make up a railway track. ...

No ready-to-run models are available in this scale, and although there is some availability of kits and components, some modelmaking skill is required. With such skill, however, excellent models can be produced in a very tiny size.

There is an active association, The 2 mm Scale Association, for modellers in this scale, who supply components, tools and jigs, publish a bi-monthly magazine, organise local chapters, and promote modelling in the scale.
