The utility model relates to the technical field of rail engineering, in particular to a safe rail flatcar capable of being held by hand to push and release hand braking, which is characterized in that a spring is connected to a brake handle and used for providing elastic force for the brake handle and enabling the brake handle to be positioned at a position where a piston of a brake fluid oil tank is kept closed; and when the brake handle overcomes the elastic force to move, the piston of the brake fluid oil tank can be opened, so that the brake fluid oil tank provides driving force for the brake piston cylinder to drive the brake chuck to loosen the brake part of the brake disc through the brake piston cylinder. Compared with the prior art, the novel brake handle has the advantages thatthe transparent cover is installed on the outer side of the wheel rail to be connected with the brake disc, braking is stable and reliable, the novel brake handle is designed, the working state of thebrake is converted into t
