Abstract: The present invention relates to a power car (10) for a high-speed train, comprising a body (12) and at least one power car of said body, said body comprising a roof (19) and a floor (20); the traction motor being arranged below said floor, the body further comprising an equipment room (24) defined between said roof and said floor, said technical room including: electrical equipment (33) for controlling the traction motor; and at least one fan device (34) of said electrical equipment. The ventilation device comprises: an air intake sheath (36), forming a closed pipe between an inlet (38) and an outlet (40) open on the equipment room; and a fan (42) arranged between the inlet and the outlet, so as to create an overpressure in the technical room.

Abstract: The present invention relates to a power car for a high-speed train, including: a body; a traction motor; a rheostatic brake; a first ventilation device of said rheostatic brake; electrical control equipment; and a second ventilation device for said electrical equipment. The first ventilation device comprises a first air intake sheath, the inlet and outlet of which are located on the roof of the body. The second ventilation device comprises a second sheath, the inlet and outlet of which are respectively located on the roof of the body and below the body. Each ventilation device comprises a fan arranged in one of the sheaths.
