The invention discloses a railway vehicle head opening and closing device which comprises a flexible mask, a plurality of connecting rod assemblies, a coupler, a first support for installing the connecting rod assemblies and a second support for installing the coupler, and the bottom end of the flexible mask is fixedly installed on a vehicle head; the first bracket is mounted on the car coupler through a fastener; the flexible mask comprises a mask body and a quartered cover which is arranged at one end of the mask body and can be unfolded towards the periphery of the outer side, and the quartered cover is matched with one end of the mask body when buckled. The opening and closing device is simple in structure, manual operation does not need to be conducted on the opening and closing device, the elastic piece is in the stretching and stretching state in the natural state, and when two vehicles are linked, the elastic piece is compressed, so that the opening and closing device is convenient to use. The opening and closing devices at the heads of the two vehicles can automatically open or close the end cover top and pop up the vehicle structure support through interaction force and combined use of the flexible face cover, the connecting rod assembly and the vehicle couplers, so that butt joint of the vehicle couplers at the heads of the two vehicle bodies is facilitated, coupling operation is completed, and uncoupling operation can be conveniently carried out.
