The invention discloses a backup braking control method of a locomotive. A solenoid valve, a backup braking valve, an acting valve and an equalizing air cylinder are involved in the method. According to the method, when emergency braking is applied in a backup mode, an air charging channel of the equalizing air cylinder can be automatically closed, and air in the equalizing air cylinder can be discharged; in the process, the position of a handle of the backup braking valve has no influence on train braking, and the situation that air is charged into the equalizing air cylinder and consequently train releasing is caused will not occur even though the backup braking valve is located at a releasing position of normal locomotive running. The invention further discloses a backup braking device and a locomotive with the backup braking device.
