Audiences had the same experience with the train sequence when I saw it in Auckland. One of the stunt men lost his leg as a result of being injured during the filming of the train sequence. PIty that Melbourne (cinerama cinema number 40) never had a proper 145 degree curved screen but only 120 degrees. The screen was only 64ft by 23 ft. The cinema was completely gutted in 1970 and small shops built inside the former auditorium and which could be accessed from the side street. Years later the former cinema was restored to what it would have originally looked like and it is now used as a function centre. The cinema was also situated underneath the Regent (now a live theatre).I still vividly remember seeing "How The West Was Won" in Cinerama when it first came out (Plaza Theatre, Melbourne Australia). During the train wreck sequence everyone including me was either holding onto their seats or covering part of their eyes. It was so spectacular! When this "RailRoad" sequence finished, the whole audience gave a long round of excited applause and took several minutes to calm down. I knew one of the three projectionists and he said it happened all the time after this sequence. I have the BluRay with Smilebox, but there's just NOTHING like a live experience like this on the big Cinerama screen. (Pics from original program attached).
