The S-scale, known also as the S-gauge, for model trains is designed on the ratio of 1:64 [that is, 3/16 inches = 1 foot] and fits between the popular HO and O model train scales. It met the demands for a scale which was larger than HO [which was considered too small by many model railroaders] but smaller than the popular O scale thus allowing track layouts to be constructed in smaller spaces.
Although S-gauge model trains had been around since the early part of the century, it began to boom with the advent of the re-designed American Flyer model trains first produced by The A.C.Gilbert Company in Connecticut, USA, during the late 1930s. The famous American Flyer model trains, which had been produced since the early part of the century initially as clockwork model trains, then later, as electric trains, were radically re-designed by Gilbert when he bought the original company. These trains were built to S-scale but ran on standard O-gauge tracks.
Some years later Gilbert introduced another of his radical modifications – he re-designed the tracks for the S-scale trains, moving away from the traditional three track rail used in model electric trains to that...
