Michael I have only ever eaten properly on a train twice; once in 1957, when my dad took me to London on the 'Master Cutler' express when it was still a steam train. We had a lovely breakfast (and coffee!) in the restaurant car. It was a real treat for both of us. Dad was very proud of the train, because it was Sheffield's own express. A year later it the name would be taken by a diesel engine and he said it never had the same romance.
In 1965 I was travelling home from London, where I worked, and treated myself to a Pullman seat, sharing a compartment with a young architect who kindly bought me lunch! I had mushroom soup, and chicken in a white wine sauce. I can't remember what he had. He was telling me about the new crematorium he was involved designing in Grantham, where he got off. I almost never travel on trains these days.
