M.H.M.
As far as I know the interiors are taken up with light sockets on the floor, etc and silhouettes in the windows. I suppose you could gut them and build interiors and new lighting from scratch so maybe not "zero". It's why I didn't buy them, but someone who actually owns them should chime in. I actually have a Union Pacific Lionel Passenger set like that. I wouldn't want to gut it and upgrade it.
