In the recent years, the occurrences of terrorist attacks in metro systems have increased noticeably, as illustrated for instance by the Tokyo, Paris, Madrid, and London attacks. Indeed, several efforts aim at improving the resilience of the metro coaches in order to Increase the resilience of metro vehicle to terrorist bomb blast, through the selection of vehicle materials and structural design, to speed-up the recovery following an attack, allowing the rail system to return to normal operation quickly and to reduce the attractiveness of metro systems as a target for attack. Such efforts include the European-funded FP7 SECUREMETRO project, which reached its conclusion in June 2013, and gathered 11 partners from United Kingdom, Spain,
France and Italy. SECUREMETRO aimed at bringing new solutions in fighting the consequences of damages caused by internal blast in metro vehicles. A first full-size blast test was performed to assess the performance of current rolling stock faced to a blast. The second trial consisted of a series of small-scale blast tests of unitary material samples in order to assess their behaviour and the improvement over existing materials. The final stage of the project then consisted of
integrating the new solutions in a demonstrator vehicle, and submitting it to the same blast test as the existing vehicle. The paper presents the results of the SecureMetro projects to improve the resilience of the metro vehicle to protect passengers and staff.
