Like Walt Disney, Johnston loved steam trains and owned many throughout his life. One of these, a steam locomotive he named "Marie E.", was later sold to John Lasseter, who continues to maintain and operate it. Brad Bird also worked with and admired both Johnston and Thomas, so much so that he gave them both cameo parts in The Iron Giant and The Incredibles.
