These slam-door carriages, with a door for each compartment, are definitely what I saw in the UK in the early 1990s. (I'm sad I didn't get to ride in one.) I wondered at the time if the door could be opened when the train was in motion or if it had a safety interlock like an amusement park ride, I'm sure the correct answer is the former!
Structual strenght due to the doors may also have been an issue , but the seperation issue was what saw them off , and i think caused preservation outfits to have to do major work to use them on excursions .
I'm assuming from responses that such coaches were, as I assumed, much less common in North America. I don't think I've ever seen a US historical drama depict them.
