Network Rail has secured regulatory approval to operate drones beyond the visual line of sight of pilots, paving the way for a new generation of remote infrastructure monitoring and security operations across Britain’s railway.
Working in partnership with drone specialist heliguy™, the organisation has received authorisation from the Civil Aviation Authority (CAA) to deploy remotely operated drones on both its Western and Anglia routes, initially at sites in Gloucester and Romford.
The approval marks a significant milestone for the railway industry, enabling drones to be controlled remotely from heliguy’s Operations Command Centre in Newcastle while carrying out inspections and surveillance hundreds of miles away.
The capability allows Network Rail to collect live aerial data without requiring pilots or operational staff to be physically present at trackside locations, potentially transforming how infrastructure is monitored and how incidents are managed across the network.
The authorisation follows approximately 16 months of collaborative work between Network Rail, heliguy and the Civil Aviation Authority to demonstrate that Beyond Visual Line of Sight (BVLOS) operations can be conducted safely within complex railway environments, including busy urban areas.
The approval has been granted under the CAA’s UK Specific Operations Risk Assessment (SORA) framework, which governs advanced drone operations.
For the rail sector, the development represents a major step forward in the adoption of digital technologies and remote asset management.
Network Rail believes the technology will provide faster access to critical operational information, helping teams make better-informed decisions while reducing the need for trackside inspections and improving workforce safety.
Simon Gillibrand, Operations Director for Network Rail’s Western Route, said the technology would improve operational efficiency while helping minimise disruption.
“This is about giving our teams better, quicker access to information so they can make the right decisions on the ground and keep trains moving safely,” he said.
“In a busy operational railway, being able to assess infrastructure remotely will help us plan work more effectively, respond faster when issues arise, and ultimately keep disruption to a minimum for passengers and freight customers.”
The drones will utilise automated “drone-in-a-box” technology, allowing routine and repeatable flights to be conducted throughout the working week without requiring pilots to attend each location.
Equipped with both high-resolution visual cameras and thermal imaging systems, the aircraft will provide detailed inspection data and real-time situational awareness to operational teams.
Potential applications include infrastructure monitoring, incident response, asset inspections, route security, trespass management and crime prevention.
Network Rail also expects the technology to strengthen collaboration between operational, engineering and security teams by providing a shared real-time view of conditions on the ground.
Richard Barke, Route Crime and Security Manager for Anglia Route, said the capability could significantly improve incident management and recovery.
“Being able to see what’s happening on the ground in real time will support faster, more informed responses to incidents,” he said.
“While this is still an emerging capability, the potential to improve service resilience and recovery is clear.”
The approval is particularly notable because of the complexity of operating drones around live railway infrastructure and in densely populated areas, where regulatory requirements are significantly more demanding than standard commercial drone operations.
The project also demonstrates how rail infrastructure owners are increasingly turning to automation, digital monitoring and remote operations technologies to improve efficiency while reducing operational risk.
For suppliers and technology providers, the successful deployment could create wider opportunities across the rail sector, particularly in areas such as asset inspection, predictive maintenance, security monitoring, data analytics and artificial intelligence-enabled infrastructure management.
Although the initial deployments at Gloucester and Romford will focus on trial operations, the programme is expected to provide valuable evidence for a wider rollout across the national rail network.
If successful, the initiative could establish a blueprint for how advanced drone operations are integrated into critical infrastructure management, not only within rail but across the wider transport, utilities and infrastructure sectors.
As Network Rail continues its drive towards greater digitalisation and smarter asset management, the introduction of remotely operated BVLOS drones represents another step towards a more connected, data-driven railway capable of responding more quickly and efficiently to operational challenges.
