Gn15


Gn15 is a rail modelling scale, using G scale 1:22.5 scale trains running on H0/00 gauge track, representing minimum gauge and miniature railways. Typical models built are between 1:20.3 and 1:24, or up to 1:29.
Normen Europäischer Modellbahnen NEM 010 specification defines IIp for modelling gauge.

History

Gn15 modeling is a relatively new phenomenon in the model railroading world. While the idea of this scale has existed for some time, as evidenced by the early efforts of Marc Horovitz, editor of Garden Railways magazine, Gn15 did not gain any measure of popularity until the Sidelines range of models. Following the advent of these kits, a few other lines of kits became available.
Initial community development took place on Yahoo email groups, but these have been superseded by the forums at as the primary form of communication between the far flung practitioners of this scale.

09, GNine and related scales

Alongside Gn15 other modeling scales have developed to cover both the modelling of minimum gauge lines in scales smaller than G, and 'miniature' lines in G scale.
O9 or On15 is the use of N gauge track in 7mm scale to represent a 'minimum gauge' line. In comparison GNine is the use of 9mm track to represent 'miniature' lines. GNine is a 'flexible' term for scale, referring to modelling using garden railway scales and N gauge track. GNine models can be built to scales between 7/8" and 1:35 representing anything between gauge and miniature railways.
