ScotRail, in partnership with Clarus Networks Group, has launched a transformational connectivity project that sees the world’s first deployment of a rail-certified Low Earth Orbit (LEO) satellite antenna. This landmark deployment delivers high-speed, resilient internet access to trains operating across some of the UK’s most remote rail corridors setting a new global benchmark for digital rail infrastructure.

Trains operating on rural routes from Inverness to Wick, Thurso, Kyle of Lochalsh, and Aberdeen have been equipped with a next-generation onboard system powered by Starlink’s Rigid Terminal, which has now achieved full certification for use in rail environments.

The solution has been developed in close collaboration with SpaceX engineers, ensuring it meets the stringent performance, safety, and environmental standards required for rail deployment. Unlike legacy satellite or terrestrial connectivity solutions, the Starlink terminal is engineered to deliver consistent, high-throughput connectivity under the dynamic conditions of the rail environment — including vibration, varying altitudes, and severe weather exposure.

Achieving certification to the EN50155, EN50121, and EN45545 standards confirms the terminal’s suitability for critical transport applications. These include electromagnetic compatibility, electronic equipment resilience, and compliance with fire protection requirements in rail vehicles. The result is a ruggedised, high-performance connectivity solution that delivers enterprise-grade reliability, safety, and speed uniquely adapted to the needs of modern rail.

Driving Value Across Passenger and Operational Systems

The ScotRail deployment supports a wide range of digital enhancements, benefiting both customers and frontline rail operations:

• Improved passenger Wi-Fi, enabling streaming, browsing, and productivity even in remote regions;
• Wi-Fi calling, allowing passengers and train crew to make voice calls over the internet where mobile coverage is unavailable;
• GPS tracking of rolling stock, enabling real-time location data to support joined-up public transport and better service information;
• Live access to onboard CCTV, supporting rapid incident response, passenger safety, and enhanced situational awareness;
• Enhanced onboard passenger information systems, with more accurate and timely journey updates.
• Passengers will easily identify upgraded trains via new on-board signage and will also experience a redesigned Wi-Fi landing page upon connection.

Delivering Rural Impact, Setting a Global Standard

The project supports broader efforts to improve digital services in rural areas, addressing the long-standing connectivity gaps that have impacted community resilience, mobility, and economic development. By delivering stable, high-speed internet to even the most isolated parts of the rail network, the deployment plays a direct role in enabling smarter travel, improving service quality, and encouraging confidence in public transport.

This solution is already being considered for wider roll-out across the ScotRail fleet, with potential to cover other remote lines including the West Highlands, Stranraer, Dumfries, and the Borders. It is also influencing the requirements of future rolling stock procurement ensuring that connectivity is not a bolt-on, but a core part of train design and delivery.

Global Implications for Rail Connectivity

Clarus Networks is leveraging this milestone to accelerate rail connectivity projects around the world. The company is currently engaged in deployments and partnerships across Europe, the Middle East, Australia, and North America, helping rail operators modernise their onboard systems, streamline operations, and meet rising passenger expectations.

In these environments often marked by sparse mobile coverage and complex terrain LEO satellite solutions provide a cost-effective, rapidly deployable alternative to traditional infrastructure. By integrating these technologies into certified, rail-ready platforms, Clarus is helping global rail networks deliver the same level of connectivity seen in urban centres without the need for fixed infrastructure or long lead times.

Mike Butler, Director of Rail & Innovation at Clarus Networks, said: “This project marks a major step forward in closing the digital divide for rural rail routes. By harnessing the power of Low Earth Orbit satellite technology, we’re able to deliver fast, reliable connectivity in some of the most remote parts of the UK rail network. This approach helps overcome the coverage and performance limitations of traditional mobile networks a challenge faced by rail operators globally. We’re proud to deliver the world’s first rail-certified LEO satellite deployment in partnership with ScotRail and SpaceX, helping shape the future of rail communications improving both operational performance and the experience for passengers.”
