Welcome to the S Page."S" indicates we are modeling in S-scale which in North America is a ratio of 1 to 64 or 1:64 or 1 foot in the model equals 64 feet in the real world. S-scale trains run on .883 inches track. Standard gauge track in the real world is 4ft 8.5 inches between the rails. So in S-Scale standard gauge track is represented by .883 inches track or 16.5 millimeters between the rails.

S gauge is a scale in model railroading. Modeled at 1:64 scale, S gauge runs on two-rail track with the rails .883 inches apart. S gauge is sometimes confused with standard gauge, a large-scale standard for toy trains in the early part of the 20th century.

1:64 scale trains first appeared in England in the early 20th century. The first trains marketed as S gauge appeared in the 1930s when American Flyer marketed a 1:64 scale train that ran on 3-rail track similar to that of Lionel. Following World War II, American Flyer introduced an S-gauge train running on two-rail track for greater realism, and S gauge entered its heyday, which ended around 1959. However, during that period, Lionel outsold American Flyer nearly 2 to 1. American Flyer's parent company went out of business and the brand was sold to Lionel in 1967.
