Somewhat related question which I couldn't find in any archive: from all indications, "Compartment cars" (
http://en.wikipedia.org/wiki/Passenger_ ... l%29#Coach) were typical on European trains < 1950, at least for first class. Any historical drama I've ever seen, and I've seen a lot, usually features this seating arrangement on European and English trains of the pre-War period. Two recent examples being the 2nd Sherlock Holmes movie, and Downton Abbey. As late as Scotland in the early 1990s I saw them being used on a train, but not a train I was taking...I think they are seldom used anymore though. But my impression is these were never as common on American trains - is that true?
LOL at the thought of Amtrak reintroducing this as a super-first class Acela service: "it's such a bother to wait behind other people to get off the train. I'd much rather have my own door!" From the Acelas I saw for years leaving Union station when I had an office with a view of K Tower, Amtrak has NO problem selling out first class as it is.
