Abstract: The present invention concerns a railway power car comprising: A body (12) extending in a longitudinal direction (X) and defining a technical room (22); and cabinets (15) accommodated in the technical room. The power car comprises at least two rails (28) disposed on the floor, each of said rails extending in the longitudinal direction, an upper part (42) of each of said rails forming a first means of joining with a cabinet; each cabinet comprises at least one foot (56), said or each foot comprising a second means of joining (60, 62) capable of mating with the first means of joining of one of said rails, each first means of joining and each second means of joining being configured so that each cabinet can be fastened to said corresponding rail at an infinite number of positions along said rail.

Abstract: There is provided an underfloor duct which enables inspection of electric equipment to be easily performed, has a simple structure, and hardly allows water to intrude into a duct passage. An underfloor duct according to an aspect of the present invention is an underfloor duct, provided under a floor of a railcar, for storing electric equipment including a cable. The underfloor duct includes: a box having a frame that projects upward, and an opening that opens downward; and a lid that closes the opening and forms a duct passage between the lid and the box. An end portion of the box is located outside an end portion of the lid in a car width direction.

Abstract: A vehicle with a ventilation system that includes a chassis and vehicle body. The vehicle body is mounted on the chassis, and has a floor, a ceiling, a front section, and a back section. The front section includes control instrumentation and an adjacent driver seat. The front section further defines a vent opening and has a duct mounted on the ceiling. The duct extends from the vent opening, and has at least one air portal structured and arranged to direct air over the driver seat. The duct includes a main passage and projections, which are partially defined by sloping walls so as to provide a region of less constrictive air flow as compared to an intake passage. The intake passage extends upward from the vent opening to inhibit moisture from entering the main passage, and the projections and slope of the intake passage serve as a conduit to drain away any moisture that does manage to enter the main passage.

Abstract: A sanitary system for a locomotive wherein the treatment tank is protected from freezing by the use of the heat available in the exhaust air removed from the toilet compartment. A sealed and insulated compartment is formed around the treatment tank, and a vent is connected between the toilet room and the insulated compartment. A suction line located at an opposed position in the insulated compartment is used to direct the flow of air from the toilet room, through the insulated compartment around the treatment tank, to the locomotive exterior. By eliminating the need for heat tracing of the treatment tank, this invention reduces the cost and energy usage of the locomotive sanitary system.

Abstract: An apparatus for ventilating the cabin of a locomotive wherein the ducts serve both a ventilating and a structural function. Horizontal duct provides support for floor in place of one or more of the regularly spaced joists. Horizontal duct may include stringers recessed into sound absorbing insulation within the duct. Vertical duct is formed in part from a portion of a wall of the control compartment of the locomotive cabin, thereby eliminating the need for separate wall sections. The space saved by using such structures for dual purposes may be used to increase the cross-sectional area of the ventilating apparatus, thereby allowing the speed of fan to be reduced to provide the desired ventilation at a reduced level of sound.

Abstract: This invention has an object of providing an air conditioner for a railway vehicle which can restrict a reduction in the introduced volume of outside air during a high-speed running of a vehicle and which can achieve lower noise. To achieve this object, the air conditioner for a railway vehicle includes an external cover 4 provided along the same surface as a vehicle surface, an air intake port 5 with a periphery provided on the external cover 4 and having a roundness in the cross-sectional configuration of an inside edge portion 12a of the intake port periphery, an air intake louver 11 disposed in the air intake port 5 to intersect a vehicle running direction, and an air exhaust port 3 for exhausting air that has been heat-exchanged, wherein an upper end surface 11a of the louver 11 is recessed from the surface of the exterior cover 4, and a cross-sectional configuration of the edge portion 11b of the upper end surface 11a has a roundness.

Abstract: An off-highway machine such as an agriculture harvester has an enclosed cab and a pressurizing blower or fan assembly for developing a primary or rapidly moving flow of air theretoward and directing a pressurized stream of a away therefrom. An apparatus is arranged proximate to and in operable combination with the blower or fan assembly on the off-highway machine for providing precleaned air to the enclosure.
