The invention discloses a locomotive and an air backup braking system and method thereof. The system comprises a backup balancing air cylinder, a backup braking valve connected to the backup balancing air cylinder and a backup relay valve connected to the backup balancing air cylinder and a main air pipe. The emergency braking protection system further comprises an emergency braking protection unit which comprises a control air cylinder used for storing compressed air with the pressure equal to that of the train pipe, and the emergency braking protection unit is used for cutting off a passage between the backup balancing air cylinder and the backup braking valve according to the pressure of the control air cylinder and the pressure of the train pipe. A passage between the backup balancing air cylinder and the atmosphere is conducted, the pressure of the backup balancing air cylinder is discharged to zero, and meanwhile, a passage between the backup relay valve and the main blast pipe is cut off; or; and a channel between the backup balancing air cylinder and the backup brake valve is conducted, a channel between the backup balancing air cylinder and the atmosphere is cut off, and meanwhile a channel between the backup relay valve and the main blast pipe is conducted.
