HI Mike Wyatt, I never actually saw photos of the real ones. In fact, I may have always thought, as a boy, that they were made up by Lionel just for fun. It is a real treat (pun intended) seeing them as they actually were. Thank You!

P.S, The coolest boy in my neighborhood had an A-B-B-B-A of the Santa fe, and we thought it was the best locomotive ever.
