A determination unit (76) in a device for a railway vehicle determines the state of a service solenoid valve (20) based on a response time h1 of a commanded pressure (AS) to an opening-closing command signal (G) and a change rate (α1) of the commanded pressure (AS) that changes according to a change of the opening-closing command signal (G) (steps S110, S120, S130, S210). The determination unit (76) further determines the state of the relay valve (30) based on a response time (h2) of the output pressure (BS) to the commanded pressure (AS), a change rate (α2) of the output pressure (BS) that changes according to a change of the commanded pressure (AS), and a difference between the commanded pressure (AS) and the output pressure (BS) (steps S140, S150, S160, S170, S220, S230).
