S Scale Model Railroading

American Flyer began in Chicago producing clockwork, Wide Gauge, and O‑gauge trains. In the late 1930s, A.C. Gilbert purchased the brand and later introduced S‑gauge trains—3/16" scale on two‑rail track—after World War II. Gilbert’s company was eventually bought by Wrather Corp. and closed in 1966, after which Lionel acquired the American Flyer name, tools, and dies.

S‑gauge trains, known for their two‑rail track and Pull‑Mor power, fueled a long‑standing rivalry with Lionel that still energizes collectors. Today, Lionel continues producing American Flyer trains, while other companies—such as RFG, American Models, and MTH—make compatible parts, rolling stock, and accessories. Once simple toys, American Flyer trains are now prized collectibles and a foundation for many modern S‑scale model railroaders.
