Mel, like I said in my email to you, you can return your cars for any reason... I will refund the model price.
These cars are modeled after PULLMAN designs used by many roads. Plastic productions are always like this. If you want a purely prototypical car, you could find a Precision Scale one for about $600, unpainted in 2R, then you will have to convert it to 3 Rail.
