The invention provides a hand braking system of a railway vehicle and a railway vehicle. The hand braking system comprises a hand braking machine body; and a brake release indicator solenoid valve; wherein an air inlet of the solenoid valve is used for total air compressed air to enter, an air outlet of the solenoid valve is connected with a brake release indicator, and an exhaust port of the solenoid valve is used for communicating external air; the brake release indicator and the solenoid valve are provided with two air paths: an air path communicating the air inlet of the solenoid valve, the air outlet of the solenoid valve, and the brake release indicator, and an air path, through which the total air compression air is discharged after passing the air inlet and the exhaust port of thesolenoid valve. The connection and disconnection of the solenoid valve respond to two air paths of the brake release indicator and the solenoid valve; the control circuit is used for receiving mechanical actions of the hand braking machine body and driving the solenoid valve to be connected and disconnected in the hand braking state and the release state of the hand braking machine body respectively. The railway vehicle comprises the hand braking system. The embodiment of the invention solves the technical problem that whether the hand brake of the rail vehicle is applied or not cannot be identified.
