Yes, there were many more countries were trains were made; have a look at this list: http://www.tcawestern.org/manufacturers.htm
And I can recommend the book by Pierce Carlson if you want more answers: https://www.amazon.com/Toy-Tra...arlson/dp/0060156147
I do not know which of these trains show up on American markets; you are closer to that than I am.
Note that the beginning of standardization of toy-trains was done in Germany by Märklin.
