Automatic cardumping system 12 times faster than system it replaced, has effectively doubled capacity of 74-mi railroad for hauling high grade iron ore pellets to Taconite Harbor, Minn; with new system, bottom-dump railroad cars are opened by automobile tires, mounted on right hand side (in direction of movement) of each car, riding over inverted rails; because train never stops, 100-car train can be dumped in as little as 5-min.
