ABSTRACT OF THE DISCLOSURE The present invention relates to ventilating equipment for railway rolling stock and an operating method thereof. This ventilating equipment includes a low-pressure supply air blower, a high-pressure supply air blower, a low-pressure exhaust air blower, and a high-pressure exhaust air blower. This ventilating equipment ventilates a car interior during the travel of a train outside of tunnels by means of the low- pressure supply air blower and the low-pressure exhaust air blower. The car is ventilated during travel in tunnels by means of the high-pressure supply air blower and the high- pressure exhaust air blower. The high-pressure supply air blower and the high-pressure exhaust air blower produce a higher discharge pressure than a changing external pressure during high-speed travel in tunnels, thereby preventing the propagation of an influence of the changing external pressure into the car interior. The ventilating equipment is capable of preventing an increase in power consumption of the entire ventilating equipment by interlocking, or changing over, between the high-pressure supply air blower and the high- pressure exhaust air blower and the low-pressure supply air blower and the low-pressure exhaust air blower.
