If I recall correctly the MT (Kadee) stock car is a model of an NYC car. After Ringling Bros. and Barnum & Bailey combined (merged) there was only one train and one show that traveled around the country. In the late 1940's post war era they bought alot of surolus WW II streamlined hospital cars and put together two trains and shows the Red Unit and the Blue Unit. Later these trains were replaced with upgraded cars continuing up to the present trains. It does seem a bit odd that MT now chooses to do blue cars,when the red train is far from complete, these new releases should be red in my opinion, Nate Goodman (Nato).
