Abstract: FDS software was used to establish the fire model of high- speed train, the changes of heat release rate and temperature were analyzed under 4 scenarios, and the influence of the location of the fire source on the development of fire in the train was researched. The results showed that when the fire compartment is located in the front of the train, flash-over phenomenon in the compartment has a large scope of action and strong destructive force, the rescue is difficult. As the position of the burning carriage moves back, the air flow inside the carriage inhibits flash- over and dilutes the flammable gas and heat effectively in the carriage, thus increasing the possibility of escape. 

Key words:  , train internal fire, fire compartment location, temperature, FDS
