The term HOn30 (and sometimes HOn2½) is generally used when modelling American prototypes while HOe is used for European prototypes. In the Britain the term OO9 is sometimes used. 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 railways.
H0e represents narrow gauges between 650–850 mm (25.59–33.46 in), though it’s often used to represent 600 mm (1 ft 11 5⁄8 in) gauge railways as well. In strict scale H0e represents a theoretical gauge of 783 mm (2 ft 6 13⁄16 in), which does not exist as a prototype. But this is very close to the gauge of the 750 mm (2 ft 5 1⁄2 in) gauge railways most widely used in Germany, 760 mm (2 ft 5 15⁄16 in) gauge railways Bosnian gauge most widely used in the former Austro-Hungarian empire, 800 mm (2 ft 7 1⁄2 in) gauge rack railways in Switzerland as well as to the 2 ft 6 in (762 mm) gauge used in parts of the British Empire.
OO9 gauge narrow gauge railways in OO scale are railways on N (9 mm/0.354 in) gauge track in 1:76 scale ratio
