Most American Flyer in the O and S gauge of that era use what are series wound motors - or universal motors. These were initially designed for use with the AC toy transformers of the day, but can be run on DC without major issues*. These items generally do not have a suffix, but occasionally an AC suffix will be applied.

As a presumed cost cutting measure, some American Flyer locomotives were manufactured with DC motors. These cannot run on AC. These almost always have a DC suffix.

*These motors run hotter on DC and can result in unwanted magnetisim

So an "AC" engine is the same as always and was only given that suffix to differentiate it from a "DC only" loco...?

I had always understood that these would actually run better ( and cooler) on DC...
