Really do like the American Flyer O Gauge. I have one from 1937/8, a "Hudson" engine, I had to restore due to it being painted solid black by previous owner. Although not all original now, it runs great and is built well. It was originally numbered 1681 according to Greenberg's book on American Flyer O Gauge, published 1987, ISBN 0-89778-064-7. The tender is cast aluminum (1937), has firebox glow illumination and the tender originally had American Flyer's "4th rail" whistle system, activated by special straight sections of their track. Also, on the track, curves had built in super elevation inside radius banking by use of wedge shaped ties.
