'''Gn15''' is a [[model railroad|rail modelling]] [[Scale (ratio)|scale]], using [[G scale]] 1:22.5 scale trains running on [[HO scale|H0]]/[[00 gauge]] ({{RailGauge|16.5mm|disp=s}}) track, representing [[minimum-gauge railway|minimum-gauge]] and [[miniature railway]]s. Typical models built are between 1:20.3 and 1:24,<ref>[http://www.gn15.info/faq-general#q1 Gn15.info: What exactly is Gn15?]</ref> or up to 1:29.

==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 (model railway)|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Initial community development took place on [[Yahoo]] [[email|email groups]], but these have been superseded by the forums at the now defunct [https://web.archive.org/web/20060810083317/http://www.gn15.info/ Gn15.info] as the primary form of communication between the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 (less than {{RailGauge|15"|disp=s}}) 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 scale|N-gauge]] track.  GNine models can be built to scales between 7/8" and 1:35 representing anything between {{RailGauge|5in}} gauge and {{RailGauge|12.25in}} miniature railways.<ref>[http://gnine.info/pages/intro.html What is Gnine?]</ref>
