An electrically operated vehicle includes a braking resistor in a heat sink cover. The heat sink cover has an air throughflow body having vent openings and an air throughflow direction perpendicular to a direction of travel of the vehicle. The heat sink cover includes an inlet flap on an air inflow side and an outlet flap on an air outflow side. An opening mechanism opens and closes the flaps. In the closed state, the flaps are oriented along the direction of travel and obliquely to the air throughflow direction. In a plan view of the vent openings, the vent openings are at least 90% covered by the flaps in the closed state and at most 60% covered by the flaps in the opened state. The flaps are disposed symmetrically to a vehicle center axis, and the vent openings are oriented parallel to side surfaces of the vehicle.

A cooling system for a rail vehicle having an internal combustion engine as a generator of electricity is operative to exchange heat between a cooling fluid circulating in a cooling circuit connected to the internal combustion engine and air located in an underfloor space of the rail vehicle. A heat exchanger and a fan, located in the underfloor space, are fluidly connected to an exhaust in a side skirt depending from a floor of the rail vehicle. The fan is operative to force air from the underfloor space through the heat exchanger and through the exhaust to an ambient space located on an external side of the side skirt.

A side wall for a rail vehicle body includes an outer skin, an insulating layer adjacent an inner face of the outer skin, a structural layer adjacent an inner face of the insulating layer, a finishing layer adjacent an inner face of the structural layer and a window. The insulating layer provides at least one of a thermal and an acoustical insulation. The structural layer has a longitudinally aligned top door frame member, vertical left and right door frame members and a plurality of diagonal structural members oriented at an angle comprised between 1 degree and 89 degrees from the top door frame member. The plurality of diagonal structural members defines a lattice structure having a plurality of openings there in between. The window covers at least a portion of one of the plurality of openings.

A ventilation module for a rail vehicle contains a housing having an air inlet, an air outlet, a dust discharge opening, a first cleaning station in an upper region of the housing, a cyclone separator which has a dust outlet and a cyclone air outlet. A second cleaning stage is disposed in a central region of the housing, which is arranged underneath the first cleaning stage such that air from the cyclone air outlet can reach the second cleaning stage. A dust discharge channel is connected to the dust outlet and is arranged in the central region. A dust discharge fan is set up to extract air and dust from the dust discharge channel and to remove the same through the dust discharge opening. A machine room fan is arranged in a lower region of the housing and is set up to extract air through the second cleaning station.
