The JRC has been looking into the risks of space weather impact on critical infrastructures. A new report explores the rail sector’s vulnerability and the potential impacts, in particular through interdependencies with other infrastructures. Awareness among operators and regulators worldwide is currently limited and vulnerabilities across the rail sector need to be identified, authors say.
Solar activity affects the space environment surrounding the Earth. This so-called space weather can disrupt and damage critical infrastructure in space and on the ground, including satellites, aviation, road and marine transport, banking and power grids. Society relies on these infrastructures and services, which have become inter- dependent and are therefore more vulnerable to space weather.
Railway networks could be affected in case of an extreme space weather event due to direct impact on system components, such as track circuits or electronics, or indirectly via dependencies on power, communications, and progressively on Global Navigation Satellite Systems (GNSS) for timing and positioning. While most space weather-related studies focus on the impact on power grids, GNSS and aviation, little attention has been paid to the possibility of rail sector disruption. However, anomalies in signaling and train control systems linked to this phenomenon have already been documented, and rail operations are dependent on other potentially space-weather prone technologies, such as power, communications, and systems for timing and positioning.
