The invention provides a parking braking system and a railway vehicle. The parking braking system comprises a brake cylinder, a transmission rod component and a brake lever connected in sequence, and is used for enabling the brake lever to locate in a brake position or a relief position through the transmission of the transmission rod component under the effect of the brake cylinder, wherein the transmission rod component comprises a first pull rod connected with the brake lever; a long round hole is formed in one end, connected with the brake lever, of the first pull rod; and the brake lever can move along the long round hole. In the parking braking system and the railway vehicle provided by the invention, as the long round hole is formed in the first pull rod, when the vehicle is braked by an air braking system, the brake lever can move in the long round hole without influencing the parking braking system so as to reduce the braking resistance of the air braking system.
