TfL Selects Partners for Emergency Services Network

Why It Matters

By delivering secure, high‑bandwidth communications underground, TfL equips first responders with the data they need to act faster, improving public safety and operational efficiency across London’s busiest transit corridors.

Key Takeaways

• Boldyn Networks holds a 20‑year TfL concession for underground mobile coverage
• EE will provide 4G spectrum to power the Emergency Services Network
• Coverage will span 137 Tube, DLR and Overground stations by 2026
• First responders gain real‑time video and data, replacing legacy Airwave

Pulse Analysis

London’s transit authority is addressing a long‑standing blind spot in emergency communications by deploying a dedicated 4G network beneath the capital’s rail system. The Emergency Services Network (ESN) will replace the obsolete Airwave platform, which struggled to deliver reliable voice and data in tunnels. By leveraging EE’s 4G spectrum and Boldyn Networks’ existing underground infrastructure, TfL creates a resilient, high‑capacity channel that can handle live video feeds, sensor data and secure voice calls, all essential for modern incident management.

The partnership capitalises on Boldyn’s 20‑year concession, originally granted in 2021 to blanket the Underground with mobile coverage. The new ESN will extend that reach to 137 stations across the Tube, Docklands Light Railway and London Overground, with full deployment targeted for the close of 2026. This timeline aligns with broader city‑wide digital transformation goals, ensuring that emergency crews can access the same real‑time information platforms used by surface services. The shift to 4G also future‑proofs the network, allowing incremental upgrades to 5G as spectrum becomes available.

For the public, the upgrade translates into faster, more coordinated emergency responses, potentially reducing incident resolution times and improving passenger safety. For emergency agencies, secure, high‑bandwidth connectivity means richer situational awareness—live CCTV, biometric scans, and IoT sensor data can be streamed instantly to command centres. The project sets a precedent for other megacities grappling with underground communication challenges, highlighting how public‑private collaborations can modernise critical infrastructure without disrupting daily operations.
