Railways
Rail networks stretch critical infrastructure across thousands of kilometres of open country. Aerial line surveillance, structural inspection of bridges and rolling stock, and protection of signalling systems keep the network safe and moving.
A critical asset that cannot be fenced
A railway is critical national infrastructure with a defining vulnerability: it is linear, and it runs for thousands of kilometres through terrain no guard force can line. Every bridge, tunnel and level crossing is a potential point of failure, and much of the track sits far from any settlement. Freight corridors carry the economy's bulk goods and, in many states, the movement of strategic materiel; a single interdicted span can stall both for days.
The rail network also ages in place. Bridges, viaducts and rolling stock stay in service well beyond their original design assumptions, and structural fatigue is as much a threat to continuity as any deliberate act. Layered on top is the signalling and control system that keeps trains apart and moving, increasingly digital, and therefore increasingly a target. Rail security is thus a blend of watching an open line, assuring ageing structures, and protecting the systems that run them.
Watching the line, proving the structure, guarding the signals
Modular aerial platform kits give the network an aerial patrol it can never mount on the ground, field-built airframes that operators assemble, repair and adapt themselves, covering line, corridors and remote crossings and directing response teams to obstruction, encroachment or damage across terrain that would otherwise go unseen. This turns thousands of kilometres of exposed track into a line that can actually be watched.
Non-destructive testing addresses the structural half of the problem, using ultrasonic, radiographic and eddy-current inspection to verify the integrity of bridges, rails and rolling stock without disassembly, keeping ageing assets certified and available rather than pulled from service on suspicion. Infrastructure hardening then protects the signalling and control estate that coordinates movements, reducing the attack surface of the systems whose failure would be as disruptive as a physical break. Each is a live catalogue capability matched to how a railway actually fails.
How a rail engagement runs
The engagement opens with a briefing across the network's real geometry, the critical spans, the exposed corridors, the signalling architecture, so capability is matched to the line as it is, not to a generic template. Export-control position and the end-user-certificate chain are confirmed before representation, keeping a programme that touches national transport infrastructure governed and traceable from the outset.
Delivery is phased along the network's priorities: aerial surveillance and structural inspection where a failure would be most costly, then broader coverage, then the signalling protection that underpins the whole. In-region sustainment and operator training are part of the same engagement, so the operator's own inspectors and security teams carry the capability forward. One accountable team stays responsible from first briefing through long-term operation.

Problems this sector faces
Power grids, water systems and transport networks face both physical and cyber attack. Hardening the control systems behind them, defending the networks around them and countering the drone threat above them keeps essential services running under pressure.
Problem pageContraband, fuel and untaxed goods cross borders wherever surveillance is thinnest, draining customs revenue. Wide-area overhead surveillance and low-observable radar coverage let enforcement concentrate where the traffic actually moves.
Problem pageAgeing aircraft, vehicles and vessels stay in service far beyond their design life across much of the world. Non-destructive testing verifies structural integrity without disassembly, keeping fleets certified, available and safe, independent of the original manufacturer's schedule.

Frequently asked questions
How can thousands of kilometres of open track be watched effectively?
Modular aerial platform kits provide an aerial patrol the network cannot mount on the ground, covering line, corridors and remote crossings and directing response teams to obstruction, encroachment or damage. Instead of relying on periodic ground inspection, the operator gains a repeatable overhead picture of the exposed sections that matter most.
Can bridges and rolling stock be inspected without taking them out of service?
Yes. Non-destructive testing uses ultrasonic, radiographic and eddy-current methods to verify structural integrity without disassembly. Ageing bridges, rails and rolling stock can be certified and kept available on evidence, rather than pulled from service on suspicion or run on assumptions until a failure forces the issue.
Why does signalling need the same protection as physical assets?
Because a compromised signalling or control system can halt a network as effectively as a broken span, and recovery can be slower. Infrastructure hardening reduces the attack surface of the digital estate that keeps trains apart and moving, so the systems coordinating the whole network are defended alongside the track and structures they govern.
