I remember in the early 90s, we did Milan, Venice then Switzerland. We took the winter version of the Bernina Express from Tirano to San Moritz. No special tourist cars - just two combination cab, first class and second class cars. One guy was in second class and we were the only ones in 1st class. So I went up to the Italian engineer and I, who spoke no Italian and he, who spoke no English managed to communicate that I was a RR Museum volunteer and would love to stand in the cab with him. He let me. I was so overwhelmed with the Brusio Circular and the spectacular scenery, I forgot to take any pictures. After a few small stops, we got to one where he was getting off and he indicated I had to go back to my seat. After San Moritz, we did the Glacier Express but I will forever kick myself for forgetting I had a camera in my hand and forgot to use it.
