Need to stay connected? All of our trains offer free Wi-Fi. We're also planning to introduce superfast Wi-Fi on some sections of our network, as well as continue our project to improve coverage across the network.
Because you’re on a train, there may be areas where the signal is less strong. Bandwidth is shared with all users onboard, so connection speed may be affected as more passengers connect. Websites deemed to be inappropriate or offensive are blocked.
Our free WiFi uses 4G and 5G signals so the quality of the internet connection will vary depending on the train’s proximity to communications masts along our network.
Take a look at our coverage map to see the areas where you may find it more difficult to connect:

If you lose your connection, it’s most likely because the train is passing through an area of weak signal. Once the signal improves, your device should automatically re-connect.
We’re committed to improving WiFi coverage which is why we work closely with telecommunications companies who are working hard to install additional masts across our network.
Improving Connectivity
We have worked in partnership with BT to deliver improved Wi-Fi connectivity and speed on board our trains. All of our trains have been fitted with new Wi-Fi equipment, meaning faster browsing and easier connections. We've also been working to reduce the number of "not-spots" on our network - areas where the phone signal is too weak for a steady connection - improving internet access on more than 90% of journeys.
Trackside Equipment
We've developed a strategic partnership with Mobile Network Operators (MNOs) to improve mobile coverage on the South Western Railway network. By partnering with multiple MNOs, overall coverage is enhanced which improves the performance of on-board Wi-Fi across the network and reduces the number of coverage ‘not spots’. These upgrades mean that you'll be able to use Wi-Fi calling to improve mobile phone connectivity for voice calls.
5G Railway
We have implemented superfast Wi-Fi technology, which is installed between Earlsfield and Basingstoke. This superfast trackside solution fully integrates with our existing on-board Wi-Fi service, delivering a fantastic connectivity solution for our mainline passengers.
