British N gauge is a model railway scale and gauge, rolling stock is to a scale of 1:148,[1] track is 9 mm (0.354 in) width as with all other N gauges making track and rolling stock approximately 10% out of scale with respect to each other. The 9 mm (0.354 in) track width derives from a scale of 1:160 for 1,435 mm (4 ft 8 1⁄2 in) standard gauge rails.
Background
When N gauge was developed it proved impossible to fit the then available motors into scale models of British prototype locomotives. British railways use a smaller loading gauge than those in Europe and America, resulting in smaller locomotives. A greater body size was required on the models to accommodate the motors, so instead of adopting the correct 1:160 scale, 1:148 was used. This allows larger models, but means that the gauge is not an accurate representation of standard gauge. A similar problem and solution was adopted with OO gauge and British TT gauge in Britain. However, N since it scales to approximately 4'4½" gauge it is less out of scale than OO (4'1½") or TT3 (4'0") in representing the 4'8½" standard gauge.
Manufacturers
- Graham Farish is the most prolific manufacturer, producing British locomotives, rolling stock and buildings.
- Peco manufactures track and British outlined buildings in kit form and rollingstock.
- Dapol produces locomotives and rolling stock.
- Other companies produce kits for buildings, rolling stock and other parts - including Metcalfe models, Ratio, P&D Marsh and others.
- CJM Models produce hand built models of locomotives and other rolling stock.[2]
Former manufacturers
- Minitrix/Hornby - prior to being taken over by Marklin Minitrix produced British outline rolling stock and locomotives, which were sold in association with Hornby.[3]
- Lima - Produced some rolling stock and locomotives
- Hornby produced British outline buildings in N gauge as part of its Lyddle End range.
