Cooling and heating equipments of railroad passenger cabin is one of the most important part in keeping the good thermal comfort of the passengers. The bad performance of these equipments usually results in the comfort of the passengers. However, there is no testing method for cooling and heating equipments during manufacturing the passenger car, and calculation method is frequently used. Many railroad operators spend a lot of money for the maintenance. In this study, a new environmental performance test for railroad passenger cabin was suggested. The temperature of the chamber will be changed from $-40^{\circ}C$ to $60^{\circ}C$. The performance test of cooling and heating equipment in controlling the passenger cabin temperature was carried out under various temperature condition. The testing method to investigate the effect of artificial sunlight irradiation on the passenger cabin temperature was also suggested.
