One of the questions that have also bugged me since comming to live in Britain has finally been answered: Why can't we have trains at Christmas?
Apparently, the last time a passenger train ran on Christmas day in this country was in 1964. Why? People seem to be forgetting that not all of us believe in Santa Claus. There are lots of muslims, jews, and atheists living in this country who might want to go somewhere on Tue Dec. 25th. If they started trains again, I'd use them just for the heck of it. (A few years ago I had to see a dentist on xmas day, and was really happy with the experience -- happy to see that at least one person was doing something useful, while the rest of the country was stuffing themselves.)
But as things are going rather the other way, we can look forward to a future where there are no trains on Sundays either.
