Does anyone know of a source for an o gauge open-air observation car which shortline scenic/tourist railroads such as the Strasburg (PA) or the New Hope and Ivyland (also PA) railroads often have? I'm thinking about a car like the type that was in the film, "Hello Dolly" Has such a car ever be made for 2-rail or or 3-rail o gauge?
Did you know of anyone who's kitbashed or custom made their own?
