If a coal tipple sets alone with no conveyor, or any other feeder, does it still function in real life? Assumption is that a tipple receives, stores, sorts and delivers coal. If I have a tipple setting all alone with only a multiple use section of track connecting it to the system, is that totally unreal since there is no connection to the mine in a visible manner. Or, can a tipple set atop a mine and retrieve coal via an elevator or conveyor vertically?
