Cybersecurity in the Railway Industry: Safeguarding the Tracks of the Future Part-1

Introduction

As a child, trains were my greatest fascination. Growing up near railway tracks, I spent countless hours watching trains come and go. One summer afternoon, my father, noticing my obsession, took me on a surprise trip to the nearby train station. A family acquaintance, Mr. Murari, a train pilot, invited us into the engine room. Stepping into that space was like entering a dream—controls, levers, and the engineer’s grease-stained overalls captivated my young mind. I even got to blow the train’s whistle, a sound that still echoes in my memory as a symbol of childhood wonder.

Fast forward to today, and the train’s allure remains strong for many, including myself. However, recent train collisions and incidents in Indian Railways have raised a new concern – could these complex systems be vulnerable to cyberattacks…? This question has driven my research and forms the foundation of this blog.

The Evolving Landscape of Railways

Over the last decade, the railway industry has transitioned from a traditional, mechanical system to a highly digitized and connected ecosystem. Modern trains are now equipped with advanced digital systems for navigation, control, and diagnostics, enhancing both safety and passenger experience. Today’s passengers expect real-time updates, seamless mobile payments, and robust connectivity—demands that have accelerated the industry’s digital transformation.

However, this digital evolution also brings new challenges. The very technologies that make railways smarter and more efficient have expanded the attack surface, offering cyber-criminals more opportunities to infiltrate and disrupt critical operations.

For smaller stations which only had an up/down service pattern, these boards were pretty much ideal for quickly determining which platform the next train was leaving from and where it would stop.

Google Maps has launched a new feature aimed at making people feel safe as they navigate public transport around the world.

The app has expanded its “transit crowdedness predictions” to more than 10,000 transit agencies in 100 countries, so users will be able to find out ahead of time if their chosen bus, train or subway is likely to have lots of free seats, has hit full capacity, or is somewhere in between.

With this information, pubic transport users can decide whether they want to hop on board or wait a while. “Because, pandemic or not, no one likes standing in a jam-packed subway car,” says Google.

Cybersecurity Challenges in Railways

Modern signaling and train management systems (TMS) are at the heart of today’s railway operations, enabling more trains to run safely and reliably. These systems are rich in connectivity, utilizing wireless technologies that propel the industry into the future. But from a cybersecurity perspective, this connectivity is a double-edged sword. The increased attack surface poses significant risks, with future technologies likely to amplify these vulnerabilities.

“It is vintage by Railway standards,” said Divisional Railway Manager, Bangalore Division, Akhil Agrawal. “Equipment used for operational purposes are generally changed every 25 years due to wear and tear. We are fortunate that this machine was used for more than 40 years and it functioned perfectly well till its last day,” he said.
 
 

Preventive maintenance analytics, real-time data, augmented reality, and even robots and drones are revolutionizing railway maintenance and operations. While these innovations promise significant benefits, they also present new opportunities for attackers seeking to damage infrastructure or cause service disruptions.

What’s at Stake?

A successful cyberattack on a railway network could have severe consequences:

  • Loss of Confidence: Even a minor cyber incident could erode public trust, causing passengers to choose alternative modes of transport. This business concern, while seemingly minor, could have long-term financial impacts.
  • Loss of Sensitive Data: Beyond IT and business operations, sensitive data in railway networks could include critical firmware for signaling devices. If compromised, this data could enable further attacks on the same or other networks.
  • Decreased Availability: Denial of Service (DoS) attacks could lead to delayed or halted trains, resulting in dissatisfied passengers and potential fines for operators in some countries.
  • Damage to Infrastructure: Cyberattacks could disable critical equipment, such as smart interlocking systems, leading to extended service outages or even physical damage to railway infrastructure.
  • Threat to Human Lives: The most concerning consequence is the potential for fatalities. While the railway industry’s strong safety culture mitigates many risks, a successful cyberattack could still compromise safety in catastrophic ways.

Real-World Examples of Cyberattacks on Railways

The growing frequency of cyberattacks on railway systems is a stark reminder of how critical these infrastructures are—not just for daily transportation but as strategic assets in global conflicts. As railways become more digitized and interconnected, they present an increasingly attractive target for state-sponsored actors and sophisticated cybercriminals. The following examples illustrate the significant role that railway cyberattacks can play in the broader context of international conflicts and the future of warfare.

  • Denmark Train System Halted by Cyberattack (November 2022)
    In a significant incident, Denmark’s largest train operator, DSB, was forced to halt all operations due to a cyberattack on its IT service provider, Supeo. The attack highlights the vulnerability of critical transportation infrastructure to disruptions through third-party suppliers. In the event of a geopolitical conflict, such attacks could be used strategically to paralyze a nation’s transportation, causing widespread chaos and undermining public trust in the government’s ability to protect essential services​. https://www.securityweek.com/cyberattack-causes-trains-stop-denmark/
  • Ransomware Attack on Italy’s State Railway (March 2022)
    The Italian state railway, Ferrovie dello Stato Italiane, experienced a ransomware attack that crippled its ticketing system, preventing customers from purchasing tickets. More alarmingly, the attack later extended to operational technology (OT) systems, including signaling networks. This kind of attack on critical infrastructure could easily be weaponized in a conflict, where disrupting transportation can cripple a nation’s economy and mobility, significantly affecting military logistics and civilian morale.​ https://www.railsistem.com/blog/2023/10/27/railway-cybersecurity-the-rising-threat-to-signalling-systems/
  • Cyberattack on Belarus Railways Amid Russia-Ukraine Conflict (2022)
