<p>The trolley (5,6) has a reprocessing unit (17) either for ballast (10), for sub-materials, for a full or partial replacement or for an evacuation. The ballast or the sub-material are removable and re-installable by the reprocessing unit. The trolley is designed in such a modular manner that it is inserted at any string sort of other trolleys of a working train. A conveyor belt of the trolley is used with the reprocessing unit in a base area or in a roof area for transportation of materials to or from a specific location of a machine area adjacent to the other trolleys of the working train.</p> |
