Fires occurring on railway rolling stock may not only potentially injure passengers and crew but also damage the rolling stock equipment. It is important to evaluate the performance of materials against fire. Heretofore, the time-dependent production of smoke and toxic gases relating to combustion behavior has not been considered. Quantitative understanding of combustion behavior is important, for example heat release rates, smoke production and gas generation. In the light of this context, the authors designed and fabricated a new combustion test device that can simultaneously measure time-dependent changes of combustion phenomena through combustion tests on materials for railway rolling stock. The combustion performances of materials for railway rolling stock were evaluated based on these results.
