TfL/Boldyn/telco's roll-out of mobile coverage in London across LUL and the Lizzy line has been frustratingly slow, and dates have slipped repeatedly. There's a forum thread chronicling the project and the successive press releases as goals have been watered down: https://www.railforums.co.uk/threads/lu-elizabeth-line-4g-update.240342/ https://www.railforums.co.uk/threads/lu-elizabeth-line-4g-up... Proper (incl tunnels) coverage was promised "soon" after the Elizabeth Line opened. Indeed, the trains all advertised a completely pointless TfL WiFi SSID since day 1, which still doesn't work en-route because there's of course no mobile network. This news is a good step in the right direction, but will still only work on platforms and in ticket halls. Let's see what actually gets achieved by the end of 2024.
