ABSTRACT

The carriage seats including two seats and three seats are made of steel frame, fire-retardant cloth and sponge. When there is a fire accident in a carriage, the fire cannot be put out using the portable extinguisher. There are four parts in the carriage shell including metal plate carriage body, paint, fire proof glue and glass wool. The outer frame part is finished using different types of steel. The flat surface on both sides of the model carriage is produced by a galvanized steel sheet. The maximal Heat Release Rate of composition of actual three seats in the normal speed rail train is 1000 kW, which is higher than the high-speed rail train. The fire characteristic test was carried out using Burning model carriage in a tunnel. The standard combustion material box was ignited by cotton. The fire spread in the vertical direction from the carriage luggage to the roof.
