Track gauge conversion is the changing of one railway track gauge (the distance between the running rails) to another. In general, requirements depend on whether the conversion is from a wider gauge to a narrower gauge or vice versa, on how the rail vehicles can be modified to accommodate a track gauge conversion, and on whether the gauge conversion is manual or automated.
The difference of On2 scale, compared to its nearest alternative (On30), is that On2 scale equates to the correct track gauge for 2 ft prototypes - such as Maine "Two Footers" and the many industrial operations that used or continue to use this gauge - including existing 21st century sugar cane operations in Australia, Fiji, Indonesia.
A 2 inch (50.8 mm) gauge of standard gauge locos gives a scale of 1:28.25, not so far off the 1/29 used by some manufactures with 45 mm (1.772 in) gauge track. In the grand tradition of model rail gauges often being narrower than the full scale equivalent ( 00 scale being the classic example) this is deemed perfectly acceptable.
If the tire is not checked, it has the potential to cause vibration in the suspension of the vehicle on which it is mounted. In tire retail shops, tire/wheel assemblies are checked on a spin-balancer, which determines the amount and angle of unbalance. Balance weights are then fitted to the outer and inner flanges of the wheel. [2]
Steam locomotives can be designed for more than one gauge, by having, for example, reversible wheel hubs that suit two alternative gauges. This was done in the 1930s and beyond in Victoria for possible gauge conversion, though no engines were ever converted in this manner other than one heritage engine ( R766 ).

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 ...
