We have an #4018 union pacific set purchased in 1940 from Henry Newgard & Company in Chicago. I can’t find info on this.
Pictures would help in identifying your trains.

GMF,
[#welcome] to the forum.
Your set is from early in the Gilbert era of American Flyer Trains, after the manufacturing of trains was moved from Chicago to New Haven Connecticut. It is an O gauge, 3 rail set. What kind of information are you looking for?
This link will take you to the 1940 Catalog page that shows your set.
