The invention provides a roadblock removing device, a vehicle body and a railway vehicle. The roadblock removing device comprises a cowcatcher, the windward side of the cowcatcher is provided with at least one flow guide pressure relief hole, and the flow guide pressure relief hole is obliquely arranged from outside to inside and from top to bottom. The pneumatic resistance of a train can be reduced, so that the operation energy consumption is reduced, the weight of the cowcatcher can be reduced, and light weight is realized.

    本发明提供一种排障装置、车体及轨道车辆,其中,排障装置包括包括排障器,所述排障器的迎风侧设有至少一个导流泄压孔,所述导流泄压孔从外向内从上向下倾斜设置。本发明能够减小列车气动阻力从而降低运行能耗,同时可以减轻排障器重量,实现轻量化。
