Transport

Rail and metro systems move millions of people a day on signalling and power systems built to last decades. Logistics hubs move goods on automation that never stops.

How the process runs

From signal to station

Signalling sets safe routes and keeps trains apart, traction power drives them, stations and tunnels keep passengers safe, and an operations control centre supervises the whole line. Depots and logistics hubs keep fleets and freight moving.

  1. Stage 1: Signalling and train control

    Interlocking sets safe routes, and train protection stops trains that pass signals or overspeed.

  2. Stage 2: Traction power

    Substations feed the overhead line or the third rail.

  3. Stage 3: Rolling stock

    Trains carry their own network for doors, brakes, propulsion and diagnostics.

  4. Stage 4: Stations and tunnels

    Ventilation, fire systems, escalators and platform doors keep passengers safe.

  5. Stage 5: Operations control centre

    The control centre supervises trains, power and stations for the whole line.

  6. Stage 6: Depots and logistics

    Depots maintain the fleet, and logistics hubs sort and ship goods.

Attackers rarely go straight for a controller. They travel through these shared systems, so this is where we look first.

For product makers

Building systems for rail and logistics?

Signalling, train systems and station equipment are built by specialist suppliers, and railway cybersecurity standards put requirements on them directly.

What makers build
  • Signalling and interlocking
  • Train control and management systems
  • Traction power equipment
  • Platform screen doors and station systems
  • Warehouse and sortation automation
What customers and regulators ask of the product
CLC/TS 50701:2023

Railway cybersecurity built on IEC 62443, with requirements for suppliers and integrators as well as operators.

IEC 62443-4-2 and IEC 62443-4-1

Railway operators ask for certified components and a secure development process.

EU Cyber Resilience Act

Railway products are not excluded: those sold in the EU need CE marking under the CRA from 11 December 2027.

For plant owners

Where it gets hard, and how we tackle it

We start from how your process runs, fix what matters most first, and use what you already own wherever we can.

  1. Safety systems built for isolation

    Interlocking and train protection were engineered as closed systems. Modern signalling adds IP networks and remote diagnostics to them.

    How we tackle it

    We work inside the railway safety case: security requirements per CLC/TS 50701, zones agreed with the signalling supplier, and security changes planned with the safety approval process, not around it.

  2. Radio links can be abused

    In August 2023, more than 20 trains in Poland were stopped by unauthorised radio-stop signals. The analogue signal carries no authentication, so no break-in was needed. Source: The Record

    How we tackle it

    We review every wireless link, from train radio to maintenance Wi-Fi, for what an outsider could trigger and how you would detect it.

    Gap Assessment
  3. Suppliers hold part of the operation

    In October 2022, trains across Denmark stood still for hours after a supplier shut down its servers following an attack. Drivers lost the app they rely on for speed restrictions.

    How we tackle it

    We map operational dependencies on suppliers and plan how to keep running, or stop safely, when one of them fails.

  4. Life safety shares the network

    Tunnel ventilation and fire systems often share networks with passenger information and CCTV.

    How we tackle it

    Separate zones for life-safety systems, with only the conduits they need and monitoring on each.
