Standard HOe couplings are most often used. An alternative is the Greenwich coupling which is compatible with the standard couplings but can be magnetically operated. MicroTrains or [[Kadee]] couplings intended for N gauge can also been used.

OO9 is a model railway scale and gauge combination of 4 mm scale and 9 mm (0.354 in) gauge tracks, which models a prototype track gauge of 2 ft 3 in (686 mm). It is a common choice in the United Kingdom for the modelling of narrow gauge railways whose prototype gauges lie approximately between 2 ft (610 mm) and 2 ft 6 in (762 mm). The 9 mm (0.354 in) track gauge is used by N gauge model railways, a common commercial scale, which means that a selection of wheels and mechanisms is readily available.

2 ft (610 mm) gauge railways were common in Britain, but 2 ft 6 in (762 mm) and particularly 2 ft 3 in (686 mm) were quite rare. This leads to difficulty in achieving correct scale when the gauge is widened, particularly with outside framed engines.

There is currently no commercially available ready to run support for OO9, although Peco do sell the necessary trackwork, and small manufacturers have made limited runs of models from time to time. The modeller is therefore generally dependent on kit manufacturers, of which there are many, adapting models made for OO, or scratch building. Many OO9 modellers also use HOe equipment. In November 2012, Peco announced the launch, during 2013, of a range of ready to run 009 coaches and wagons, based on prototypes of the Lynton and Barnstaple Railway.[1] Although no locomotive models were announced, in the March 2013 edition of Railway Modeller Magazine, Danish manufacturer Heljan announced an 009 loco based on the L&B Manning Wardle 2-6-2Ts. In July 2014, Bachmann announced a range of ready to run 009 products, starting with a Baldwin Class 10-12-D and a number of wagons, primarily used by the British War Department during World War I.

Standard HOe couplings are most often used. An alternative is the Greenwich coupling which is compatible with the standard couplings but can be magnetically operated. MicroTrains or Kadee couplings intended for N gauge can also been used.

Using N gauge 9 mm track to model narrow gauge prototypes is also popular in HO scale model railways. In Europe, this is known as HOe while in the United States this is called HOn30 or HOn212. As the latter indicates, 9 mm in HO scale is 783mm in the theoretical prototype, closer to 2 ft 6 in (762 mm) gauge.

3 ft (914 mm) gauge lines (common in Ireland and the Isle of Man) are generally modelled in 4 mm scale but with 12 mm (0.472 in) gauge track, which is known as OOn3.
