Buster IS railroad on film for me. Nobody else compares.
He probably HOPED he'd be laughed at for this shot and did it with enthusiasm.
Ah ha! I got half you's now ... Wait till I pose
There is also a much later, color but silent, short film with him on a putt-putt rail-speeder. I think the way it pans out, he more or less "crosses the continent" on it, doing all kinds of oddball "daily life" things along the way, never stopping. I think it was on CN maybe. I like that one a lot. ( Time to hit YT )
