In this study, we delve into the darker aspects of railway technology, revealing how easily accessible domestic hardware tools can compromise the seemingly infallible robustness of signaling systems. We demonstrate how these accessible technologies can be utilized to devise strategies that potentially threaten train circulation in Spain. Our research presents a critical analysis of the vulnerabilities present in the railway signaling systems, highlighting the ease with which these systems can be tampered with, using tools that are readily available to the general public. Through a combination of theoretical insights and practical demonstrations, we offer a comprehensive overview of the risks associated with such vulnerabilities.
