The general nature of fire problems on energy‐conservative passenger trains is described, including a description of vehicle structures and lightweight design. Effects of high energy demand, tunnels and high maximum speeds on fire safety are outlined. The considerations used in design analysis are described, beginning with the development of a ‘worst‐case fire scenario’. Typical combustible materials are considered and some of the reasons for choices are given. Notes on cavity and chimney effects emphasize the importance of clear objectives. Structural fire resistance is examined, and the basis of conventional recommendations analysed. The application of British Standard 6336 guidelines on fire tests and hazard assessment is examined. Limitation of fire load density is described, and some problems of calorific value determination outlined. Sources of ignition and hazards from passengers are defined. Flammability and flame‐spread control are discussed, and rate of heat release is referred to in the context of fire behaviour. Problems of passenger escape linked to flashover, smoke and combustion gases are dealt with briefly.
