Challenges in rail digitalization 

Digitalization and connectivity are reshaping railway systems, but they also introduce significant cyber risks. Critical rail assets – from signalling systems and control centres to operational networks and rolling stock – are now targets for sophisticated cyber threats. Legacy infrastructure, remote access points, and growing IT/OT convergence leave operators vulnerable to disruptions that can compromise safety and service reliability. 

In response, rail organizations must adopt a proactive, strategic approach to cybersecurity – one that goes beyond compliance to deliver operational resilience and long-term risk reduction.
