Petards Rail has articulated that Britain’s railways are emerging as a prime target for cyber-criminals, with the convergence of ageing infrastructure and digital systems creating security vulnerabilities across the network.
New government legislation is said to threaten tougher penalties for operators failing to protect essential services, as recent incidents demonstrate the sector’s exposure to sophisticated attacks capable of paralysing transport links and endangering passenger safety.
The UK’s Cyber and Resilience Bill is expected to tighten oversight of train operators, infrastructure managers and suppliers.
Building on existing NIS Regulations, the legislation reportedly introduces enhanced enforcement mechanisms, mandatory coordination with the National Cyber Security Centre, and stricter supply chain security requirements.
Railway operational technology is said to present its own set of challenges for cybersecurity professionals.
Unlike conventional IT networks, rail systems prioritise continuous availability and passenger safety above all else, meaning even brief disruptions can have a severe impact.
David Muse, Chief Technical Architect at Petards Rail said: “While a cyber-attack on office systems may result in lost data, an attack on railway operational technology could threaten human safety and paralyse critical infrastructure.”
The problem is said to be compounded by outdated equipment.
The company has articulated that whilst corporate IT systems receive regular security updates, safety-critical railway technology often operates for years without patches due to lengthy certification processes.
This creates exploitable gaps that sophisticated attackers can leverage.
The Rail Safety and Standards Board has introduced comprehensive guidance on cyber-assurance for software-based railway control systems, whilst international standard IEC 63542 provides a framework for securing rolling stock, signalling, and infrastructure.
The Office of Rail and Road has reportedly conducted risk assessments identifying the most vulnerable systems that pose the highest safety risks if compromised.
These are said to include digital interlockings, train control platforms and remote diagnostics.
Industry collaboration is reportedly accelerating through the Rail Cyber Security Working Group and government-backed intelligence-sharing platforms, enabling operators to exchange threat data and defensive strategies.
However, according to Petards Rail, experts warn that fragmented approaches remain problematic.
Muse explained: “Achieving robust cybersecurity requires collaboration across the entire fleet lifecycle.
“Manufacturers, operators and rolling stock companies must work together, sharing threat models and conducting integrated security testing to identify system-level vulnerabilities before attackers do.”
Petards Rail has stated that the expansion of connected technologies, including predictive maintenance systems, remote diagnostic and real-time passenger information, continues to broaden potential attack vectors across the network.
Protecting increasingly interconnected systems demands both technical controls and organisational resilience.
Muse commented: “Operators need the capability to recover from incidents rapidly whilst maintaining safe service delivery under pressure.”
With rail digitalisation accelerating and threats becoming more sophisticated, the sector is said to face mounting pressure to give more urgent attention to cyber-vulnerabilities before a major incident forces change.
