Most of my single level experience is of the Crescent and I notice two designs of lounge car on it. One has the food service area in the middle, with dining type seating at one end and lounge-type seating at the other. The other is a car which is clearly blocked off smoking compartment at one end and dining- type seating at the other. That is not very good for me, a non-smoker, because I do not get the kind of lounge seating I prefer. What cars are on other trains, like the Lake, Shore, the Silver trains, etc?
