When a train comes, piston wind enters a station mostly and shafts do not work. When a train leaves, the temperature at the hallway increases (in summer) or decreases (in winter) by 4 to 6 ℃ due to the air brought into the station. In spring or autumn, energy can be saved by way of bringing outdoor air into stations through s...
