I agree with Mark on this one. I also would not dump my present PE for a more DeLuxe one. As far as more detailed passenger cars, those too would be a non-starter for Lionel. Too much modification would be needed. Besides, a few years ago American Models re-released their full length Pullman cars. Palace Car company also offers an interior upgrade for them. Here’s what mine look like. I also came up with a way to adapt American Models’ Budd interiors to their heavyweight cars with only three cuts to the Budd interior.
The café car's interior (last photo) was freelanced based on the Palace Car interiors. When illuminated in a dark room, it look fine.
