When the war ended, Gilbert began producing true S scale S gauge trains in 1946 under the American Flyer mark.
As early as 1948, an industrially produced narrow-gauge railway on tracks with a model gauge of 16.5 mm was available from the French company Allard.
Today's S gauge and S scale modelers have a greater selection and higher quality products, from a wide range of manufacturers, than at any time in the past.
In addition to the basics of locomotives, rolling stock, and track, various manufacturers now offer S scale structures, detail parts, figures, other scenic items, bridges, and more.
Strictly speaking, scale is the ratio of the size of a model to that of its prototype and gauge is the distance between the track railheads.
The National Association of S Gaugers serves as an organization to promote all forms of S gauge model railroading.
