This podcast from Transport Security International Magazine examines the security measures in place for the U.S. passenger rail system, particularly regarding the threat of terrorist attacks. It highlights the challenges of securing such a vast and complex network, which comprises 98 independent rail systems operated by numerous state, local, and regional organisations. The podcast discusses various threats, including explosives, insider threats, and domestic violent extremism, and explores the preventative measures being implemented, such as vulnerability assessments, emergency planning, increased security personnel, and advanced technology. The podcast concludes by emphasising the importance of identifying and addressing potential threats, particularly from lone actors and those with grievances, in order to ensure the safety of passengers and staff.
