PROBLEM TO BE SOLVED: To provide a vibration damping device for a railroad vehicle capable of reducing the cost of the railroad vehicle, and optimizing vibration suppression control. SOLUTION: The vibration damping device for the railroad vehicle comprises a damping force variable damper 3 which is interposed between a vehicle body 1 in a railroad vehicle V and a truck 2 for supporting the vehicle body 1 to suppress the vibration of the vehicle body 1 in the horizontal lateral direction with respect to the advancing direction of the vehicle V, a detection means 5 for detecting the vibration acceleration of the vehicle body 1 in the horizontal lateral direction with respect to the advancing direction of the vehicle V, and a control means 4 for performing the skyhook semi-active control of the control force F for suppressing the vehicle body vibration generated by the damping force variable damper 3; and further comprises an analysis means which analyzes the vibration acceleration to be detected by the detection means 5 to obtain the data for evaluating the ride quality.
