The invention provides a control method for a parking brake cylinder of a railway wagon, which comprises the following steps of: directly communicating the parking brake cylinder with a spring energy storage mechanism with an auxiliary air cylinder, charging air to the auxiliary air cylinder and the parking brake cylinder through a train pipe to constant pressure, enabling the parking brake cylinder and an air brake system to be in a complete release state, and controlling the parking brake cylinder according to different braking requirements of the railway wagon. And a parking brake cylinder is controlled to adopt different braking modes. The parking brake cylinder is connected to the auxiliary air cylinder, the work of the parking brake cylinder is controlled through the air pressure change in the auxiliary air cylinder, the parking brake cylinder can be in a braking state only under the condition of long-time parking braking, the parking brake cylinder is in a relieving state under other conditions, and th
