Britain’s Terrible Train Wi-Fi Could Finally Get a Satellite Fix
Britain’s terrible train wi-fi could finally get a satellite fix as the government announced plans this week to spend £57 million rolling out low-earth orbit satellite connectivity across 1,400 trains on mainline nationalised services. The Department for Transport aims to increase wi-fi availability from the current 50-60% to at least 90% and multiply speeds between fivefold and tenfold over the next five years. The announcement follows a 2025 report by network testing company Ookla that ranked the UK’s on-board wi-fi speed 16th out of 18 major European and Asian countries, with average speeds of just 1.09 Megabits per second (Mbps — compared to 64.58 Mbps in Sweden and 29.79 Mbps in Switzerland. Transport Secretary Heidi Alexander is expected to formally launch the plans this summer.
Why Train Wi-Fi Is So Bad
The current system relies on the same 4G and 5G mobile networks that passengers use on their phones. The Department for Transport’s own assessment is blunt: “If there is no signal outside the train, neither the wi-fi nor direct services will work.”
When trains pass through tunnels, cuttings, or rural stretches of the network, the signal vanishes. The on-board wi-fi vanishes with it. Greater Anglia, which operates services between London and Norwich, confirmed its wi-fi relies on 3G and 4G mobile data signals and noted that quality varies depending on location and the number of passengers using the connection Greater Anglia statement, May 2026.
Many operators also limit access to video and music streaming sites to manage bandwidth. The result is a system that fails most dramatically when it is needed most — on full trains at peak times.
The average UK home broadband speed is 285 Mbps, according to Ofcom. The gap between the connection passengers expect and the one the railway delivers is the consequence of decades of infrastructure investment that prioritised tracks and signals over digital connectivity.
The Satellite Solution
Low-earth orbit satellites — the same technology that powers services like Starlink — will connect directly to receivers installed on train roofs. The signal will come from space, bypassing the ground-based mobile networks that have failed to deliver consistent coverage.
The government’s ambition is to increase wi-fi availability from 50-60% to at least 90% and multiply speeds by a factor of between five and ten. Trials have already been conducted with operators including LNER, South Western Railway, and Great Western Railway, as well as in Scotland Department for Transport connectivity trials, 2025-2026.
The £57 million investment is modest in the context of national infrastructure spending. It is roughly the cost of a single mile of new motorway. The fact that it has taken until 2026 to commit this sum to a problem that has defined the passenger experience for more than a decade reflects what critics describe as a failure of priority rather than technology.
The satellite receivers will not solve every problem. Tunnels will remain dead zones. The contention problem — too many devices sharing the same connection on full trains — will persist unless receivers are sized for peak load rather than average load. The history of railway procurement suggests peak load is rarely the specification.

The Passenger Experience
Rebecca Kendall, 36, takes the train about six times a month in her role as head of operations for a charity. She estimates she can manage only about half the tasks she would normally complete at her desk. When she has audio calls, she warns colleagues in advance that she might lose connection.
“I just wouldn’t risk having an important video call,” she said. “I would never plan one.”
Many passengers have already adapted to the unreliability. Some download TV shows and music before travelling. Others bring books or play cards. Some use their phones as hotspots, though the underlying connectivity problem remains the same.
Nelson Ntumba, 29, often experiences “major issues” accessing train wi-fi. But sometimes, he said, the digital detox has an unexpected benefit — a journey without notifications.
For those travelling for leisure, the absence of connectivity is less critical. Maya Lane, 23, usually reads or crochets on train journeys. But she said operators should not advertise wi-fi as a benefit of rail travel if it is unreliable. “Sometimes people pick trains so they have the option of working while they’re travelling,” she said.

FAQ: UK Train Wi-Fi Satellite Upgrade 2026
Why is UK train wi-fi so bad?
Train wi-fi relies on the same 4G and 5G mobile networks as passenger phones. When the train enters tunnels, cuttings, or rural areas with poor signal, the wi-fi fails. The UK ranks 16th out of 18 major European and Asian countries for on-board connectivity speed.
How will the satellite fix work?
Low-earth orbit satellites will connect directly to receivers on train roofs, bypassing ground-based mobile networks. The government plans to install the technology on 1,400 trains over five years.
How much will the upgrade cost?
The government has committed £57 million to the project. Transport Secretary Heidi Alexander is expected to formally announce the plans this summer.
Will satellite wi-fi work in tunnels?
No. Tunnels will remain dead zones. The satellite signal requires a direct line of sight to the receiver on the train roof.
When will train wi-fi improve?
The rollout is planned over five years. Trials have already been completed with LNER, South Western Railway, and Great Western Railway.
