Oh! American Flyer is S-scale! I had no clue. Is it 2-rail then?
AF and s Gauge is 2 rail.
So it has nothing to do with O gauge / O scale, right?
No, but Lionel currently is one of the manufacturers of AF S gauge trains.
What scale are the dimensions and what gage is the track?
Scale dimensions are 1/64 or 3/16th to a foot. Track gauge is appox 7/8th of an inch.
