Modelling British railway prototypes
Modelling British railway prototypes is a hobby where railway modelling is applied to British prototypes. For historical reasons, British model scales have developed somewhat separately from those in other countries, and the commercial standards; 00 gauge and British N gauge are unique to British prototypes. The railways in Britain were for the most part standard gauge, and consequently most support focuses on these scales. Narrow gauge, and broad gauge standards also exist. British modellers tend to focus on British subjects, and most of the commercial support is British-based, but modellers of British prototypes exist across national boundaries. Standard gauge prototypes

Commercially available standards 

There are two major commercial standards; 00 gauge (4 mm:foot, 16.5 mm gauge), and British N gauge (2.05 mm:foot, 9 mm gauge). Ready-to-run (RTR) equipment is available in both standards. Hornby Railways and Bachmann Branchline offer major RTR support in 00 gauge; Graham Farish (part of the Bachmann group) offer RTR support in N gauge. Previously commercial support was available for British TT gauge (3mm:foot, 12mm gauge). All three of these commercial standards suffer from being too narrow to accurately represent the track gauges, and as a result, finescale standards have been developed. Finescale standards 

As a consequence, of the track gauges, plus overscale track, finescale standards have been developed. These include EM gauge (4 mm scale, 18.2 mm gauge), P4 gauge (4 mm scale, 18.83 mm gauge), 3 mm finescale (3 mm scale, 14.2 mm gauge), 2 mm finescale (2 mm scale, 9.47 mm gauge). Others have adopted H0 gauge. Narrow gauge prototypes 

The most straightforward way of modelling narrow gauge is to adopting a larger scale but with the track from the appropriate gauge. Thus, the most common standard for narrow gauge modelling are 009 (4 mm scale, 9 mm gauge) and 016.5 (7 mm scale, 16.5 mm gauge). These tend not to accurately represent real scales, so again there are products made to the smaller gauge but with sleeper spacing, etc., suitable for the larger scale narrow gauge trains.
