An object is to provide a railway vehicle which can promote energy saving by suppressing air flows into space portions around bogies of a running railway vehicle and can make bogie maintenance easy. An underfloor portion (54) is provided with a space portion (58) to accommodate a bogie (52). The space portion (58) is formed in space partitioned by an end-portion closing plate (6) rising in the height direction from an end part on the bogie side of each underside closing plate (7) which is provided downward of an underframe (55) to be approximately in parallel with the underframe (55) and the underside of the underframe (55). Each movable cover device (10A) includes a movable cover (11a) which covers the underside of the space portion (58) at least partly from a lower end part of an end-portion closing plate (6), an accommodation part (15a) to accommodate the movable cover (11a), and drive devices (13) to drive the movable cover (11a).
