The invention relates to an unloading area matched with a novel railway lorry, and belongs to the field of equipment of docks and bulk cargo fields. At present, a tipping apparatus is mostly used for unloading in places for gathering large bulk cargos, such as coal docks, power plant coal fields, and the like in our country, but novel train wagons eliminate the tipping apparatus. In order to makethe train wagons exert better self functions, a section of special overhead railway and corresponding facilities need to be matched in the unloading area so as to achieve the aims of better reducing the unloading operation cost and improving the turnover speed of the train wagons. The unloading area comprises an overhead bridge system, a dust controlling system and a draining system.
