HO Scale AutoFlood III RD Coal Hoppers

    Beginning production in 2004, the all aluminum body prototype has been produced in the thousands and has traversed all over North America. With millions of tons of coal per year being mined and hauled out of various locations across the country, you would be hard pressed to not have seen one of these prototype cars in a modern day coal train.

    This 4200 cubic foot, exterior post prototype (not to be confused with other prototype exterior post or interior post models) is primarily used as a rapid discharge car which can unload the payload in a matter of seconds via the bottom bay doors. However, the car can also be equipped with a rotary coupler at the end(s) of the car, indicated by the color blocks on the end of the car, for either bottom discharge or rotary unloading based on the infrastructure at the final destination.
