American Flyer is best remembered for the S gauge trains of the 1950's that it made as a division of the A. C. Gilbert Company. In May 1967, Lionel Corporation purchased American Flyer. Lionel's investment in new tooling has been interpreted as a sign of commitment by the manufacturer to their market segment, as well as the brand, the gauge, and the hobby in itself. Sign comes with support and is only available in one size.
