No, the real ones have dump doors on the bottom. They aren't remote controlled. Most have a mechanical opener. I know on the ones here in the Marquette Range are opened by what's basically a powered wrench mounted on a cart, which is operated by a dock man. It's moved along the string of ore cars and stopped at each car. It's attached to the shaft on the car which opens the doors and dumps the ore into the pocket. Each ore pocket holds 4 carloads and from there it is dumped into the ship's holds.
