S versus O guage

Model Railroader General Discussion (Model Railroader)

I have a late 1940’s or early 1950’s American Flyer. The boxes only list it as being 3/16. Is it a S or O guage?

Thanks

3/16ths is S gauge

Thanks. Must I use a particular American Flyer type of transformer or will any American Flyer transformer do. I have a Model- 19B transformer that was purchased years after the train set.

American Flyer S runs on AC, so any of their transformers will work for your trains. Lionel transformers will also work. The 19B should be just fine.

3/16ths is S scale. American Flyer made S scale trains that ran on O gauge track pre WWII, post WWII they were S gauge track. Even today some 3/16ths trains are made that run on O gauge track.
Enjoy
