With the rapid development of Railway Construction in China, the safety of railway trains has aroused people’s concern while solving the traffic problems of passenger flow in various cities. According to the principle of relative motion, this experiment studies the fire burning characteristics of trains at different travel speeds by changing the wind turbine frequency to adjust the wind speed. The experimental results show that when the train window breaks during travel, the fire heat release rate increases with the increase of running speed. The growth coefficient of fire increases with the increase of running speed. With the increase of train running speed, the variation of the temperature extremes of the ceiling and the temperature series on both sides of the fire source is not very large.
