PROBLEM TO BE SOLVED: To provide a pneumatic spring system of a railway vehicle which can change the air capacity without using a variable orifice.SOLUTION: A pneumatic spring system of a railway vehicle 100 includes: a pneumatic spring 20 provided in the railway vehicle 100; and auxiliary air chambers 40 communicating with the pneumatic spring 20 through an orifice. The pneumatic spring system further includes: a control device 150 which controls a height of the pneumatic spring 20; a memory storage which stores control timing; and the auxiliary air chambers 40. The pneumatic spring 20 is connected with a second auxiliary air chamber 42 of the auxiliary air chambers 40 through a cutoff valve 25, and the cutoff valve 25 is controlled by the control device 150 so that a volume ratio of the pneumatic spring 20 to the auxiliary air chambers 40 is changed.SELECTED DRAWING: Figure 3
