To provide a railway vehicle and a train whose aerodynamic sounds radiated from truck domains can be effectively reduced.SOLUTION: A railway vehicle (10) comprises a vehicle body (1), a truck (2) and plural additional members (3). The vehicle body (1) has a cavity (12) in an underside (11) thereof. The truck (2) is accommodated in the cavity (12). The plural additional members (3) are arranged in front of the cavity (12) in a traveling direction of the railway vehicle (10). The plural additional members (3) are attached to the underside (11) of the vehicle body (1) to be put side by side, leaving a mutual space in the traveling direction. Each of the additional members (3) extends in a vehicle body (1) width direction. Each of the additional members (3) has an inclined plane in a front side of the railway vehicle (10) in the traveling direction, where the more downward the plane tends to expand, the nearer it approaches the cavity (12).SELECTED DRAWING: Figure 3
【課題】台車領域から発生する空力音を効果的に低減することができる鉄道車両及び列車を提供する。【解決手段】鉄道車両(10)は、車体(1)と、台車(2)と、複数の付加部材(3)と、を備える。車体(1)は、その底面(11)にキャビティ(12)を有する。台車(2)は、キャビティ(12)内に収容される。複数の付加部材(3)は、鉄道車両(10)の走行方向においてキャビティ(12)の前方に配置される。複数の付加部材(3)は、当該走行方向に間隔を空けて並ぶように車体(1)の底面(11)に取り付けられる。付加部材(3)の各々は、車体(1)の幅方向に延びている。付加部材(3)の各々は、鉄道車両(10)の走行方向の前側に、下方に向かうにつれてキャビティ(12)に近づく傾斜面を有する。【選択図】図3
