Broader than standard gauges have been modelled using P4 standards, including Brunel's 7 ft 1 ⁄ 4 in (2,140 mm) gauge, modelled with 28.08 mm (1.106 in) track [3]: 2 [4] and Irish P4, the 5 ft 3 in (1,600 mm) Irish broad gauge modelled in P4 in 4 mm scale with 21 mm (0.827 in) gauge track.
OO gauge uses 4 mm scale with 16.5 mm gauge track, [3] [4] which is inaccurately narrow since it is correct for HO scale (1:87.1). It is the most popular standard in the UK for 4 mm scale trains [5] and is produced by the two main manufacturers in the UK.
OO gauge is one of several 4 mm-scale standards (4 mm to 1 ft (304.8 mm), or 1:76.2), and the only one to be marketed by major manufacturers. The OO track gauge of 16.5 mm ( 0.65 in ) (same as the 1:87 HO scale ) corresponds to prototypical gauge of 4 ft 1 + 1 ⁄ 2 in , rather than 4 ft 8 + 1 ⁄ 2 in standard gauge.
P4/S4 or 4 mm: 1:76.2: 18.83 mm (0.741 in) Uses a track gauge of 18.83 mm which represents an exact scaling down of the prototype at 4 mm to 1 ft scale. P4 contains an allowance for the tighter curves found on model railways in the wheel back-to-back and related dimensions.

American OO scale is a model railroad standard that has a scale of 4 mm to 1 foot (1:76) and utilises 19 mm (0.748 in) for the standard gauge track.. The standard is different from British 00 gauge (which is popular in Great Britain), as it utilises 19mm gauge track rather than HO scale 16.5 mm (0.65 in) gauge track.
Many OO9 modellers also use H0e equipment, which although built for 3.5mm scale, not 4mm, is often close enough to work alongside OO9. Standard H0e 'bemo' style loop couplings are most often used. A slimmer alternative also with a loop is the Greenwich coupling which is compatible with these standard couplings and can be magnetically operated.
The term 4 mm connector is also used, especially in Europe, although not all banana connectors will mate with 4 mm parts, and 2 mm banana connectors exist. Various styles of banana plug contacts exist, all based on the concept of spring metal applying outward force into the unsprung cylindrical jack to produce a snug fit with good electrical ...
