This gauge is represented by the EM Society (in full, Eighteen Millimetre Society). 00 track (16.5 mm) is the wrong gauge for 1:76 scale, but use of an 18.2 mm (0.717 in) gauge track is accepted as the most popular compromise towards scale dimensions without having to make significant modifications to ready-to-run models. Has a track gauge ...
Some railways, primarily in the northeast, used standard gauge of 4 ft 8 + 1 ⁄ 2 in (1,435 mm); others used gauges ranging from 2 ft (610 mm) to 6 ft (1,829 mm). As a general rule, southern railroads were built to one or another broad gauge, mostly 5 ft ( 1,524 mm ), while northern railroads that were not standard-gauge tended to be narrow-gauge.

The term HOn30 (and sometimes HOn2½) is generally used when modelling American prototypes while H0e is used for European prototypes. In Britain, the term OO9 is used. [1] All these terms refer to models of narrow-gauge railways built to the world's most popular model railway scale of HO (1:87) but using a track gauge of 9 mm (0.354 in)—the gauge used for N scale models of standard-gauge ...
Like the intermediate EM gauge standard in 4 mm scale, some modellers in 3 mm scale developed 13.5 mm (0.531 in) track gauge, but this has largely been superseded by 14.2 mm (0.559 in) gauge. Both 3 ft ( 914 mm ) narrow gauge (using 9 mm / 0.354 in gauge track) and 5 ft 3 in ( 1,600 mm ) broad gauge (using 15.75 mm / 0.620 in gauge track) are ...

All other railways use 1,668 mm (5 ft 5 + 21 ⁄ 32 in) (broad gauge); some use 1,000 mm (3 ft 3 + 3 ⁄ 8 in) metre gauge; Decauville uses 500 mm (19 + 3 ⁄ 4 in) gauge. Planned and under construction high-speed railways to use 1,668 mm ( 5 ft 5 + 21 ⁄ 32 in ) to maintain interoperability with the rest of the network.
A. Nowhere "63.5 mm" (metric) is defined as a gauge. It is a conversion outcome. I propose to remove gauge definition "63.5" completely. B. The 2 + 1 ⁄ 2 inch definition in UK is most likely meant to be the same gauge as the existing 64mm gauge. The rounding would be off 0.5mm or 1.28% (calculation: 2.5 inches (63.5000 mm) *). This would be ...
