EnglishThe present study focused on the consequence analysis of the severe transportation accident which took place on June 29th, 2009 in Viareggio (Italy). The accident followed the derailment of a train carrying 14 tank cars of LPG. The first tank car was punctured after the derailment releasing its entire content, that ignited causing an extended and severe flash-fire, that set on fire several houses, causing extended damage and 31 fatalities. A map of the damage following the flash-fire was obtained from the images collected after the accident. Con-ventional simplified tools for consequence assessment were used to reproduce the results, yielding to overconservative results. A computational fluid dynamic (CFD) model was also developed in order to perform a more detailed simulation. The presence of obstacles (e.g. walls, trees) and the shape of buildings around the railway line were taken into account, showing a good performance in the identification of the area affected by the flash-fire that followed the LPG release.
