The invention provides a synchronous action control hydraulic system and a rail car thereof. The synchronous action control hydraulic system comprises a hand pump; the load-sensitive variable pump is connected to one end of the hand pump through a pipeline, a radiator is fixedly installed at the end of the load-sensitive variable pump, one end of the hand pump is connected with a third ball valve and a fourth ball valve through pipelines, and the load-sensitive variable pump is connected with a pressure sensor through a wire. One end of the third ball valve and one end of the fourth ball valve are both in pipeline connection with a load-sensitive multi-way valve, one side of the load-sensitive multi-way valve is in pipeline connection with a second walking motor, and a first brake is fixedly installed on one side of the second walking motor. According to the synchronous action control hydraulic system and the rail car thereof, the car walking system adopts an independent load-sensitive proportional multi-way valve to drive an independent low-speed large-torque motor, and synchronization of four driving motors is achieved by inputting the same current value; accurate positioning of the vehicle is achieved through the small-flow stability of the load-sensitive multi-way valve.
