A railway vehicle vibration damping device includes: an actuator including a cylinder body configured to expand and contract when supplied with hydraulic fluid, a pump configured to supply the hydraulic fluid to the cylinder body, and a motor configured to drive the pump, and installed on a railway vehicle; and a control unit configured to control the motor. The control unit stops the motor when a current value to be provided to the motor becomes equal to or larger than a current threshold for outputting a restriction torque set to a value exceeding a rated torque of the motor.
