EM gauge (named after the track gauge of a nominal E ighteen M illimetres [1]) is a variant of 4 mm to a foot (1:76) scale used in model railways. EM was developed because OO gauge, favoured by manufacturers of British prototype models, utilised track that was too narrow. OO was developed in the UK in the 1930s as a response to manufacturers ...
As the first EM gauge layout to be exhibited, and for the extent and detail of its magazine coverage, it has been described as 'the single most important layout in the history of the hobby'. [25] A feature of the later railway was 'The Automatic Crispin'. This was a very early example of model railway automation using a form of drum sequencer.
Model gauge. 18.83 mm (0.741 in) Prototype gauge. Standard gauge. Website. Scalefour Society. Protofour or P4 is a set of standards for model railways allowing construction of models to a scale of 4 mm to 300 mm (1 ft) (1:76.2), [1] the predominant scale of model railways of the British prototype. For historical reasons almost all manufacturers ...
This gauge is represented by the EM Society (in full, Eighteen Millimetre Society). 00 track (16.5 mm) is the wrong gauge for 1:76 scale, but use of an 18.2 mm (0.717 in) gauge track is accepted as the most popular compromise towards scale dimensions without having to make significant modifications to ready-to-run models. Has a track gauge ...
From the outset, the magazine featured minority scales and standards. The premier issue had an EM gauge layout on its cover [6] and by its fourth issue featured a 2mm Finescale on the cover, Helsby, Tumill & Haddon, very much a minor scale. [7] Other minority and finer scale standards were featured from the outset too.

(1,067 mm) ^ O21 – [1] 3 ft (914 mm) ^ O16.5 – UK 7 mm scale with 00 16.5 mm gauge, used to model gauges between 2 ft (610 mm) and 2 ft 6 in (762 mm). ^ O14 – Finescale modelling of British 2ft gauge using 7 mm O scale and a unique 14 mm gauge.

Railway modelling (UK, Australia, New Zealand, and Ireland) or model railroading (US and Canada) is a hobby in which rail transport systems are modelled at a reduced scale.
