The passenger cabin of train is generally insulated from exterior environment to ensure the safety of passengers and to enhance the heating and cooling efficiency. Therefore, the IAQ management of passenger cabin is very important in aspect of amenity and health of passengers. In this study, we measured some IAQ factors influencing on the indoor air quality of passenger cabin. The measurement was carried out to investigate the PM-10, PM-2.5, PM-1.0, temperature, relative humidity, carbon monoxide, carbon dioxide leves of KTX. The results showed that the air quality of the cabin was largely satisfactory, but carbon dioxide level was relatively higher. The control of carbon dioxide levels need the extensive research in the future.
