A railway vehicle includes: a vehicle body, a bogie supporting the body and having a bogie frame (4) and wheels (2). The railway vehicle further includes a bogie enclosure structure which substantially encloses the bogie in a cavity beneath the vehicle body. The enclosure structure has two side covers (12) which cover respective external lateral sides of the bogie. The enclosure structure further has a bottom cover covering a bottom side of the bogie. Wheel holes (111, 111') are formed in the bottom cover for bottom portions of the wheels to project through.
