A subway system or mass rapid transit, underground, elevated railway, metro or metropolitan railway system is an electric passenger railway in an urban area with a high capacity and frequency, and grade separation from other traffic[1]. Due the large flows of people, the relatively ‘openness’ of the systems and the potential to cause large-scale disruption and fear , subway systems are very vulnerable for security threats.
