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.
