SWR tests Starlink wifi on Waterloo–Weymouth line
If you’re travelling between London Waterloo, Portsmouth Harbour and Weymouth this Christmas, there’s a welcome upgrade to look for. From today, Saturday 20 December 2025, South Western Railway has begun a one‑year trial of satellite‑powered onboard wifi on a Class 444 train, with early tests reporting about 97% coverage through the New Forest-long one of the route’s worst ‘not spot’ sections. Here’s what’s new and how it works.
That phrase ‘not spot’ simply means an area with no reliable mobile signal. Trains get hit hard because trees, cuttings and tunnels block radio waves, and masts can be widely spaced across national parks. On this line, some passengers previously lost internet for more than 20 minutes in the New Forest. What this means: fewer dead zones and less anxiety about a call or download failing right when you need it.
How the technology works, in plain English. Instead of relying only on 4G or 5G along the tracks, the train can also connect to low‑Earth‑orbit satellites-small spacecraft flying below about 2,000 km. Because they’re much closer than traditional TV satellites, the delay is lower, which helps streaming, video calls and cloud apps feel responsive.
For you as a passenger, very little changes in practice. You still join ‘SWR Wi‑Fi’ as normal; the clever bit is the backhaul. Antennae on the roof track satellites overhead and the onboard kit switches between satellite and ground networks as reception changes along the journey. You don’t need special hardware-just connect and use your device as usual.
Early days come with caveats. It’s one train to begin with, and performance will vary with carriage load and location. But if you revise online, upload coursework, run a small business or just want your festive film to play smoothly, you should feel a step up-especially through the forest stretch that used to be ‘offline’.
A quick explainer on ownership, because it shapes what gets prioritised. South Western Railway moved into public ownership on 25 May 2025 under DfT Operator Ltd, and ministers are creating Great British Railways to bring track and train under one publicly owned organisation once the Railways Bill passes. The government says publicly owned operators already run about a third of passenger journeys.
Zooming out, this trial sits alongside Project Reach-the plan to remove mobile dead zones on major routes, especially in tunnels. The deal will lay around 1,000 km of new fibre and fix signal blackspots in 57 tunnels, with installation expected to start in 2026 and complete by 2028. Officials estimate this model will save taxpayers about £300 million. What this means: by the time many of you start the 2028 academic year or first jobs, the worst tunnel dropouts on key lines should be gone.
SWR says this isn’t the only improvement since moving into public hands. The operator has quadrupled the number of new Arterio trains in daily service, lifting morning peak capacity into London Waterloo by nearly 12%. The trains add air‑conditioning, accessible toilets and charging points at every seat-details that make study, work and accessibility easier.
There’s also the cost side. On 23 November 2025 the government announced the first rail fares freeze in 30 years. If implemented as set out, many season ticket holders will keep hundreds of pounds in their pockets in 2026. For students and new graduates balancing budgets, that matters.
If you’re using this route over the holidays, try the onboard portal and see how it performs; passenger feedback during the trial will shape what happens next. What this means: you don’t need to change your habits-just connect as usual-but expect fewer complete dropouts and a steadier connection where it used to disappear.
