Reinventing onboard Wi Fi for the UK rail network
Reliable internet access on UK trains has long lagged behind passenger expectations and the data makes the scale of the problem clear. According to Ookla Speedtest Intelligence data from Q2 2025, the UK ranked among Europe’s poorest performers for onboard train Wi‑Fi, with a median download speed of just 1.09 Mbps. That puts the UK far behind leading rail markets such as Sweden at 64.58 Mbps, Switzerland at 29.79 Mbps and Ireland at 26.33 Mbps, with passengers in the best-performing European market experiencing speeds almost 60 times faster than those typically seen in the UK. Ookla also found that more than half of UK rail Wi‑Fi connections still run on legacy Wi‑Fi 4, with 38% using the more congested 2.4 GHz band, underlining the scale of the infrastructure challenge.
As highlighted in 'Why Wi‑Fi on Britain’s trains is so bad', the problem is structural. Train Wi‑Fi is not fixed broadband, it relies on mobile networks, struggling to maintain stable connections as trains move at high speed between masts. Physical constraints such as tunnels, cuttings and carriage shielding further degrade signal strength, leaving passengers frequently disconnected.
The result is a nationwide frustration. For a growing number of passengers, particularly business travellers, this is not just an inconvenience, but a barrier to productivity. With onboard connectivity now seen as essential rather than optional, the need for a step-change in performance is clear.
Proving a new model for rail connectivity
Motion Applied’s mission is to bring this step change to the market. Following successful deployments worldwide with operators including Deutsche Bahn and Amtrak, the latest application of Motion Applied solutions was a demonstrator trial of what reliable, high performing connectivity can actually be achieved onboard in the UK. Over a 15-week live service trial, Motion Applied partnered with Great Western Railway, Peninsula Transport, Network Train and Hitachi to deploy and test what this solution could look like. The system combined 5G/4G mobile networks with Low Earth Orbit (LEO) satellite connectivity, integrated through Motion Applied’s Fleet Connect™ software platform and powered by EDGE Rail 5G Active Antenna hardware. Instead of relying on a single network, the system dynamically aggregated multiple connections simultaneously, maintaining performance even as network conditions and physical environments changed across the route.
Delivering measurable results
The trial demonstrated that a hybrid approach can fundamentally transform onboard connectivity:
Up to 1.2 Gbps peak bandwidth
~900 Mbps average available throughput
99.75% connectivity maintained across journeys
>90% improvement in passenger satisfaction
These results were achieved across complex real-world routes spanning urban, rural and coastal environments, where traditional single-network solutions typically fail.
Transforming the passenger experience
The improvement was immediately visible to passengers. Feedback highlighted a consistently faster, more reliable connection from start to finish of the journey.
Passengers were able to:
Join video calls reliably
Work productively throughout journeys
Stream content and browse without interruption
Stay connected in previously unreachable areas
Compared with existing onboard Wi‑Fi, the trial system enabled more than 85% of passengers to do what they needed during their journey versus just 6% on current onboard solutions.
A scalable solution for the future of UK rail
Crucially, this was not a controlled lab trial. The system was deployed onto an operational GWR Intercity Express Train travelling from London to Penzance and across the Southwest, integrated within live passenger service conditions, proving that next-generation connectivity can be implemented at scale.
The trial comes at a pivotal moment for the rail industry as the UK Government increases its focus on improving digital connectivity for passengers. With £57 million earmarked in the 2025 Spending Review to enhance onboard connectivity across Britain’s railways, the results of this trial demonstrate that the technology required to transform the passenger experience already exists today.
By combining cellular and satellite networks into a single intelligent platform using Fleet Connect’s patented aggregation method and a distributed architecture of Active Antenna technology, the trial demonstrated a viable path forward for the UK rail industry, one that overcomes the inherent limitations of relying on any single network type and of traditional passive architectures limited RF losses - offering a blueprint for how future investment can deliver measurable benefits for passengers, train operators and the wider economy.
Moving beyond today’s limitations
The UK rail network’s connectivity challenges are well understood. But this trial shows they are no longer unsolvable.
Hybrid connectivity, simplification of onboard architecture and intelligently aggregating networks delivers the performance, reliability and consistency that modern passengers expect.
The future of connected rail in the UK isn’t just a vision. It’s already proven.
