STUDY ON PASSENGER TRAIN VEHICLE FIRES

The fire aspects of passenger train vehicles for two of the railway li nes (labelled as A and B) in Hong Kong are discussed. Train compartmen ts of railway line A are of enclosed construction whereas vehicles in railway line B are opened to each other. Reference is made to the smok e filling process as this is identified to be the most important aspec t in a fire. Simulations with the fire model ASET were performed in tr ain vehicles for railway line A to study the probable smoke temperatur e and smoke layer interface height for different fires. The fire zone model CFAST and the CORRIDOR menu of the fire protection engineers' to ol FPEtool are used to study the fire environment in the train vehicle s for railway line B. Results confirmed that smoke is the key factor t o consider. Recommendations for providing better fire protection desig n and fire safety management are made.
