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.
Stage 2: Traction power
Substations feed the overhead line or the third rail.
Control systemsTraction SCADAProtection relaysStage 3: Rolling stock
Trains carry their own network for doors, brakes, propulsion and diagnostics.

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

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.
- Signalling and interlocking
- Train control and management systems
- Traction power equipment
- Platform screen doors and station systems
- Warehouse and sortation automation
Railway cybersecurity built on IEC 62443, with requirements for suppliers and integrators as well as operators.
Railway operators ask for certified components and a secure development process.
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.
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 itWe 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.
Risk AssessmentRadio 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 itWe review every wireless link, from train radio to maintenance Wi-Fi, for what an outsider could trigger and how you would detect it.
Gap AssessmentSuppliers 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 itWe map operational dependencies on suppliers and plan how to keep running, or stop safely, when one of them fails.
Incident Response TTXLife safety shares the network
Tunnel ventilation and fire systems often share networks with passenger information and CCTV.
How we tackle itSeparate zones for life-safety systems, with only the conduits they need and monitoring on each.
