OOn3

OOn3
An OOn3 model of Donegal on the County Donegal Railway as around 1950. Layout by Alan Gee.
Scale per foot:	4 mm to 1 foot
Scale ratio:	1:76
Gauge:	12 mm (0.472 in)
Prototype Gauge:	3 ft  (914 mm) (Narrow gauge)

OOn3 is a model railway standard for modelling 3 ft  (914 mm) narrow gauge railways in 4mm scale scale with 12 mm (0.472 in) gauge track. 3 ft  (914 mm) prototypes were common in Ireland and the Isle of Man, but the scale is not generally used outside the British Isles. 12 mm (0.472 in) gauge track is the same as that used in TT scale and HOm, so some components used for those scales can be used. There is no ready-to-run support, so everything must be built from scratch or from kits supplied by Worsley Works, Backwoods miniatures and Parkside Dundas amongst others. OOn3 modellers have close relations with other 4 mm narrow gauge modellers, especially OO9 modelling.

Related Scales

Outside the British Isles the similar 1:87 scale is used. For European 1,000 mm (3 ft 3 ³⁄₈ in) (metre gauge) prototypes and African / Australian 3 ft 6 in (1,067 mm) gauge railways HOm is used. In America 3 ft  (914 mm) gauge railroads are modelled on 10.5 mm (0.413 in) gauge track as HOn3.
