A dual-powered railroad vehicle is provided. The vehicle includes a combustion engine having a first cooling circuit; a traction transformer having a second cooling circuit; and at least one radiator for dissipating thermal energy to surrounding air. The first cooling circuit and the second cooling circuit are configured to dissipate thermal energy via the at least one radiator. Further, a method for operating a dual-powered railroad vehicle is provided.

The air conditioning device (10) includes a heat exchanger (12) intended to exchange heat with the air circulating in the air conditioning device (10), and an air distribution box (14), extending in a longitudinal direction (X) between a front part (14A) and a rear part (14B), and in a transverse direction between two side parts (14C). The distribution box is fastened to a ceiling (5) of the driving cabin (1), and comprises: in its front part (14A), a front inlet (16) for air coming from the cabin (1), connected upstream from the heat exchanger (12), and in each of its side parts (14C), a respective side outlet (18) for conditioned air, connected downstream from the heat exchanger (12).

An electronic device includes a heat-receiving block, a heat transfer member, and fins. The heat-receiving block has a first main surface to which an electronic component is attached. The heat transfer member is attached to a second main surface of the heat-receiving block opposite to the first main surface, and transfers heat transferred from the electronic component through the heat-receiving block in a direction away from the second main surface. The fins have main surfaces and are attached to the heat transfer member with the main surfaces being inclined with respect to a horizontal plane for a vehicle being located horizontally. The fins dissipate heat transferred from the electronic component through the heat-receiving block and the heat transfer member into ambient air.

A driver's cab for an interoperable rail vehicle has a front window and a seat arrangement with two seats for operating personnel. A standard field of view is defined for each of the seats. The standard fields of view overlap at least partially in the projection thereof onto the front window. There is also described a rail vehicle.
