Abstract: The pulling device includes at least one motor; an epicyclic (or planetary) gear train comprising a first element, a second element, and a third element selected from an internal sun gear, an external ring gear, and a planet carrier, the first element being integrally secured in rotation with the output shaft of the motor, the second element being designed to drive an axle of the vehicle in rotation; the detection means detecting an anomaly with respect to the motor; the releasable locking means, that are capable of assuming a locking configuration locking the third element in rotation, and a release configuration for releasing the third element; and the control means command—controlling the maintaining of the locking means in the locking configuration when no anomaly is detected, and moving of the locking means into the release configuration when an anomaly is detected.

Abstract: An air conditioning device is provided. The air conditioning device includes a primary circuit in which a refrigerant circulates, the primary circuit including an evaporator, and a first secondary circuit in which a first fluid circulates. The first fluid passes through the evaporator to exchange heat therein with the refrigerant. The first secondary circuit includes at least one first heat exchanger in which the first fluid exchanges heat with the air. The air conditioning device further includes at least one first compartment in which the primary circuit is housed, an air treatment zone, formed outside the first compartment and intended to communicate with the inside air, and in which the first heat exchanger is housed, and at least one sealed wall, separating the compartment from the air treatment zone. A railway vehicle having an air conditioning device is also provided.

Abstract: An air conditioning device is provided which has a primary heat pump circuit having at least one primary heat exchanger with the air from the compartment, a primary compressor, a second primary heat exchanger with the outside air, and a primary expander device, and a heat storage reservoir, connected to the primary circuit, in parallel with said first primary heat exchanger with the air from the compartment. The air conditioning device also has a secondary heat pump circuit, including a first secondary heat exchanger with the air from the compartment, a secondary compressor, a second secondary heat exchanger with the air from the outside, and a secondary expander device. The heat storage reservoir is connected to the secondary circuit, in parallel with the first secondary heat exchanger with the air from the compartment.
