The top car of course is a Charles Ro woodside box car. The American Series name did not exist then and didn't come along until after USA Trains name change over. This is stock #R1958 and seems to have been upgraded with USA Trains silver metal wheels The bottom car is a old favorite no longer available, A USA Trains American Series woodside reefer car in the Burligton Northern Western Fruit Express car stock #R16044. Looks like this one was never used and is still in plastic, what a great piece of new old stock to run across
