gnine

Gn15 is a rail modelling scale, using G scale 1:22.5 scale trains running on H0/00 gauge (16.5 mm / 0.65 in) 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 300–400 millimetres (12–16 in) gauge.
