…… Communication within the tunnels was similarly problematic for responding authorities. The British Transport Police was the only emergency service that had radios capable of communicating underground. Even the London Underground Emergency Response Unit, whose primary responsibility is emergencies on the Tube network, did not have this capability. Furthermore, at the Russell Square station, none of the response agencies could communicate using radios, as the blast damaged the Transport Police's local antenna. Responders encountered these issues despite a formal review of a Tube fire in 1988 that highlighted the lack of underground communications and called for the development of a system to alleviate the problem.
