To study the fire spread in a metro carriage, fire tests in a scale model (1:3) were performed. A total of 10 tests were carried out to investigate the effect of material, fuel load, openings (doors and windows), and ignition location on the fire development. The fuel loads consisted of PUR seats, wall and floor coverings, and in some tests longitudinal wood cribs simulating luggage. Different parameters including heat release rate, gas temperature, gas concentration, heat flux and smoke density were investigated. The results show that the material and especially the luggage play a significant role in the fire development in the tested metro carriage. This proves to make the difference between minor fire spread and a carriage totally involved in the fire. The number and size of openings are also important for the fire development and maximum heat release rate. The focus of this paper is on the influence of the material and fuel load (luggage) on the fire development and fire spread.
