My God did those guys work hard. Yes this stuff is damn interesting BB. I had a treasure in my life when I moved into this house. The neighbor was a 92 year old man who moved here from Ireland in 1922 and went to work for Southern Pacific, for which he retired in 1966. I would go over there and he would tell me stories and show me pictures of the time this film was shot, he gave me a few things that I recently donated to the local train Museum at the very yard he was "yard master" I believe was the term for many years. There was a time a train had the land speed record!
