A rail vehicle includes a plurality of items of equipment provided within a compartment, an air-conditioner that conditions air flowing within the items of equipment or within a housing that accommodates the items of equipment, and a duct that delivers air between the air-conditioner and the items of equipment and having a portion extending within the compartment in a forward/rearward direction of a vehicle, in a position close to a wall of the compartment.

Conventional APUs for diesel-electric locomotives may include an AC electric generator and typically require additional hardware to be installed to convert the AC power output by the generator to DC power that can power electrical systems or charge batteries in the locomotive. According to some embodiments, there is provided an auxiliary power unit (APU) or system for operation in cooperation with a primary engine. The APU includes a secondary engine; a primary engine coolant heating system, or a primary engine lubricant heating system; a control system that automatically shuts down the primary engine and starts the secondary engine responsive to a predetermined condition; and a Direct Current (DC) power generator that generates an output voltage, the DC power generator being driven by the secondary engine.

A high speed train power unit comprising: carbody that comprises: a roof; a floor; a driver's cab at a front end of the carbody; and a technical compartment that comprises: a low voltage zone that comprises an air conditioning unit designed to condition the driver's cab, wherein the air conditioning unit is on the roof, a traction zone that comprises a rheostatic brake on the roof, and a technical zone, wherein the low voltage zone, the traction zone, and the technical zone of the technical compartment are respectively located next to each other along a longitudinal axis of the power unit; at least two bogies mounted under the floor of the carbody; and a main transformer located under the carbody between the bogies.

An operator compartment of a rail vehicle includes two front windows separated by a connection beam, a track monitoring camera attached in a lower region of the connection beam by a fastening device, and a front window roll-up sun shield which can be drawn in the interior of the operator compartment and has guides running along both sides of the front windows. The guides have lower retaining devices. In order to allow a comparably simple attachment of the roll-up sun shield and the track monitoring camera in the operator compartment, a longitudinal member is attached to a lower region of the connection beam. The longitudinal member retains the fastening device, has mutually opposite guides and has the lower retaining devices for the roll-up sun shield. An assembly device for a track camera and a front window roll-up sun shield of a rail vehicle is also provided.

A fuel deck for on-board storage and delivery of gaseous fuel for a locomotive. The fuel deck is formed between the engine deck and the trucks of the locomotive. The fuel deck includes a base for riding on the trucks, a ceiling configured to separate the fuel deck from the engine deck, and one or more support structures extending between the base and the ceiling. The support structures are configured to support the load from the engine deck, and separate the base from the ceiling to form a fuel storage compartment that is adapted to store one or more fuel tanks that contain the gaseous fuel. A fuel system including one or more fuel tanks is also provided, where each fuel tank may have more than one inlet/outlet port for enabling faster refilling or distribution of the gaseous fuel, among other considerations.

A cooling aeraulics device is for cooling an element of a rail vehicle. The aeraulics device is designed to be placed on a roof of the rail vehicle and includes a conduit, which extends substantially longitudinally in relation to the rail vehicle. The conduit includes, successively, a front portion equipped with a front opening for the intake of air, a central portion, in which is housed the element to be cooled, and a rear portion, equipped with a rear opening for the discharge of exhaust air. A surface of a transverse cross-section of the conduit evolves, from the front opening to the rear opening, so as to generate an acceleration of the flow of air in the conduit through the Venturi effect.

A foot support platform has a foot rest plate mounted pivotably on a housing of the foot platform. The lower face of the foot rest plate is supported by a spring. A mechanical detent device locks the foot rest plate in a pivot position. The foot platform is further provided with a remote-controlled mechanical locking device for engagement with the mechanical detent device. There is also described a desk having a foot platform.
