I share his fascination with trains. Two of my favorite movies with him are "The General" and "The Railrodder"; the first when he was at his peak and the latter being near the end of his career/life. In each one, his love of trains is intrinsic in his performance and in the look and feel of the movies.

Incidentally, "The Railrodder" was directed by the same guy who went on to make this cult classic...
