Max: "The cars are a mix of Kato, Walthers, Rapido and Con-Cor. Some have Fox Valley wheels, some have Atlas 36 metal, and some
have Kato. Some are truck-mounted, and some are body mounted."
Sounds like my passenger trains! I don't have the Rapido, but do have AMB core kits and Bachmann full domes, so just as big a variety of cars, and the added bonus of NWSL and Intermountain wheels to go with your list.
