The embodiment of the invention provides a railway locomotive vehicle, as well as a pantograph reduction circuit and a pantograph reduction control method of the railway locomotive vehicle. The pantograph reduction circuit comprises a first controller and a main circuit breaker, wherein the first controller is connected with the main circuit breaker in parallel, the first controller comprises a first contact, and the main circuit breaker comprises a main circuit breaker contact; the main circuit breaker is used for switching off the main circuit breaker contact when the main circuit breaker is switched off; the first controller is used for receiving a switching-off command sent by a CCU (Center Control Unit) when the main circuit breaker is switched off, executing the switching-off command of the CCU, controlling the first contact to be switched off and enabling the railway locomotive vehicle to reduce a pantograph. According to the railway locomotive vehicle, the pantograph reduction circuit and the pantograph reduction control method, provided by the invention, the damage to an overhead contact line can be effectively avoided, and the safety of the railway locomotive vehicle is ensured.
