O14 is a set of

narrow-gauge railways in 1:43.5 (7 mm scale

) using 14 mm (0.551 in) gauge track.

The first published O14 standards appeared in

HO standards, less 2.5mm coupled with coarse scale OO wheelsets set to 12.5 mm back to back. A subsequent article in 1953 provided details of his layout. Very little more happened regards the development of O14 until Roy C Link published a new set of standards (1993 — revised 1994) in his magazine Narrow Gauge and Industrial Railway Modelling Review. They were developed for his range of O14 kits — now produced by David Janes under the name KBscale. They are based on the proven 4 mm scale EM

standards (BRMSB) and are reasonably close to exact scale especially considering the variations to be found in prototype nominal 2 ft (610 mm) gauge railways.
This scale/gauge combination is managed by the O14 Group (an informal web based society dedicated to finescale 7mm narrow gauge modelling) and supported by the 7mm Narrow Gauge Association.
