Those with the caveat of multiple road appeal have been done to death in O, and in HO, where every boxed set once contained an off-center cupola ATSF "metal" caboose lettered from A to Z. Cabooses are the most individualistic of cars, which is why there is a custom builder and once unique but difficult kits. Too bad, as another thread addressed, brass cabooses are so expensive. As are brass freight cars, but unique ones are available from Rich Yoder. Unique and plastic molds are not compatible. Plastic molds demand high volume.
(Anybody ever high-railed a Yoder car? I'm guessing not easy due to underbody detail?)
