Abstract (en)
In the ventilating method for rolling stock a gradient of change in the pressure of air flowing in air flowpassages communicating between the inside of a vehicle and the outside of the vehicle is obtained and both flowpassages for drawing air from the outside of the vehicle into the inside of the vehicle (31), and for exhausting air from the inside of the vehicle to the outside of the vehicle (40), are closed when said gradient is equal to or higher than a predetermined value or said pressure is that in the outside of the vehicle.
