F1 Connectivity Powers New GWR Train Wi-Fi

Technology initially developed for Formula 1’s broadcasting and operational communication systems is now being tested on UK rail services to improve the passenger Wi-Fi experience on fast-moving trains. The communications systems, which maintain stable data links at speeds above 200mph during F1 events, are adapted for rail applications operating at speeds up to 125mph.

Great Western Railway (GWR), alongside partners Peninsula Transport, Motion Applied (formerly McLaren Applied), Network Rail and Hitachi, has commenced a two-month pilot to deploy a hybrid network that combines ground-based 5G and low-earth-orbit (LEO) satellite connectivity on an Intercity Express Train.

Motion Applied leverages motorsport data link expertise

The GWR pilot utilises antenna technologies and dynamic beamforming concepts borrowed directly from Formula 1 communications.

The hybrid system employs trackside 5G infrastructure to send focused connectivity beams to trains, while onboard systems seamlessly switch to satellite links when cellular signals weaken, thereby mitigating traditional dead zones encountered in rural and semi-urban railway corridors. 

Nick Fry, Chairman of Motion Applied, highlights: “Motion Applied recognised that rail networks have struggled with onboard WiFi for customers and we have used technology originally developed for F1 cars to reliably connect a fast-moving vehicle by reducing signal dropouts and seamlessly switching cell networks.”

Regional transport digital backbone led by Peninsula Transport

Peninsula Transport is supporting the initiative as part of broader regional ambitions to modernise transport infrastructure across the South West and South Wales.

Councillor Dan Rogerson, Lead Member for Rail on the Peninsula Transport Board, states: “This is a major milestone in our mission to modernise transport infrastructure across the South West and South Wales.

"It’s not just about passenger Wi-Fi, it is about a whole new digital backbone for our transport networks.”

The hybrid connectivity approach aims to establish consistent high-speed internet service across extensive rail routes, overcoming obstacles posed by variable terrain and signal availability.

Collaborative effort with Network Rail and Hitachi on rolling stock connectivity

Network Rail and Hitachi contribute technical infrastructure access and system integration expertise to the trial. The collaboration tests how layered communication methods can deliver reliable data not only for passenger connectivity but for operational needs such as train diagnostics and scheduling.

The trial collects performance data across different network conditions to evaluate the hybrid model’s resilience before considering a broader deployment.

Its work reflects a growing alignment between telecommunications and transport engineering to develop smart, connected rail services utilising cutting-edge hybrid networks.
