Lionel re-introduced S gauge trains and accessories under the American Flyer name in 1979. Another S manufacturer, American Models, entered the marketplace in 1981 and is now also one of the major S suppliers. S-Helper Service, another major S gauge manufacturer of locomotives, rolling stock, track and other products, began operations in 1989 and delivered their first S products in 1990. In 2013, S-Helper Service was sold to MTH Electric Trains. And while the S scale market has seen a number of brass model manufacturers, today the major brass model supplier in S scale and S gauge is River Raisin Models. 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.
