To provide a rail vehicle which can secure a large space to be attached with equipment under the floor of an underframe that is made thinner, while maintaining strength.SOLUTION: A rail vehicle operating along a rail track is constituted of a body structure which comprises: an underframe 35 forming a floor face; side body structures erected at both end parts in a width direction of the underframe; and a roof body structure mounted on upper end parts of the side body structures. The underframe is composed of: an extrusion material which has a vehicle outside side plate 35b; a vehicle inside side plates 35a arranged at distance from the vehicle outside side plate; and plural connection plates 35c connecting between the vehicle outside side plate and the vehicle inside side plate. The underframe comprises: spaces 38 formed between the vehicle outside side plate and the vehicle inside side plate; screw seats 50 inserted in the spaces in a longitudinal direction of the underframe; and reinforcement members 36 mechanically and discretely connected to the respective screw seats and arranged under the vehicle outside side plate.SELECTED DRAWING: Figure 4 【課題】厚さを薄くしながら強度を保持した台枠の下面側である床下に、機器を取り付ける空間を広く確保できる軌条車両を提供する。【解決手段】軌道に沿って運行される軌条車両であって、床面を形成する台枠３５と、台枠の幅方向の両端部に立設される側構体と、側構体の上端部に載置される屋根構体と、を有して構体が構成され、台枠は、車外側面板と、車外側面板に隔置される車内側面板３５ａと、車外側面板３５ｂと車内側面板とを接続する複数の接続板３５ｃと、を有する押し出し形材で構成されており、車外側面板と、車内側面板と、の間に形成された空間部３８と、空間部に台枠の長手方向に沿って挿入されるねじ座５０と、ねじ座に離散的に機械締結されるとともに車外側面板の下方に配設される補強部材３６と、を備えた。【選択図】図４
