K Freight Car Brakes
The initial USRA specifications call for KC 10-12 air brakes to be applied to the box cars and KD 10-12 air brakes to be applied to the hoppers and gondolas of either the Westinghouse or New York Air Brake Company's manufactures.
KC-10-12 brakes have unit brake cylinders and auxiliary reservoirs while in the brakes of the KD-10-12 schedule the cylinders and auxiliaries are detached.
