Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. EM gauge is a variant of 4 mm to a foot 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 finding they were unable to fit the motors of the time into British prototype small boilered locomotives when scaled at the globally popular HO scale's 3.5 mm to a foot. As the scale was increased to 4 mm to the foot to make the locomotives larger, the track gauge was left at 16.5 mm, and hence is too narrow to correctly depict the prototype's track gauge of 4 ft 8 1 2 in.show more
