This ongoing rollout of mobile coverage across the Tube network is being delivered to TfL at no financial cost. This is made possible through a concession agreement with Boldyn Networks. All four major mobile network operators, Three UK, EE, Vodafone, and Virgin Media O2, are participating in the initiative.
Beyond passenger services, the expanded infrastructure will also support the new Emergency Services Network (ESN). This network is designed to provide first responders with immediate access to critical data, images, and information in real-time during emergency situations.
Future expansion plans
TfL and Boldyn Networks are also working to introduce mobile coverage to underground sections of the Docklands Light Railway (DLR). Discussions are also underway to bring connectivity to the Windrush line between Highbury & Islington and New Cross. The majority of the Northern, Bakerloo, and Metropolitan lines are anticipated to have tunnel coverage by the end of summer 2026.
