Madrid City Council will completely renew the radio communications network of the M-30 tunnels, a system that has been in operation for almost two decades and is vital for coordinating emergency services and keeping drivers informed underground. The tender for the project starts today, Wednesday, with a budget of 4.8 million euros.
Why you need a renovation. The 48 kilometers of M-30 tunnels register 488 million users a year, according to advance from The World. The current radio communication system is practically the same with which these underground galleries were inaugurated almost 20 years ago. Like any technology, requires updates to continue providing service and guarantee quick responses to any incident.
What systems maintain communication. Just like inform In the middle, the infrastructure has two differentiated networks that allow coordination between security forces. The TETRAPOL system covers the National Police and Civil Guard, while the TETRA connects the Municipal Police, Firefighters and SAMUR. Furthermore, according to collect El Mundo, these systems guarantee the operation of analog emergency channels, Madrid Calle 30 communications and commercial FM stations.
All this works thanks to two radiating cables installed on the roof of the tunnels: one exclusively for emergency services and another for the rest of the transmissions. “What makes it possible for this system to respond are radio communications. When there is an incident, the emergency services and the Police have an effective possibility of coordinating between themselves,” explains Antonio Jesús Tocino, managing director of Madrid Calle 30, to El Mundo.
When will the works start and what improvements will they bring?. As well as inform In the middle, the work will begin in spring 2026 and will continue for 13 months, until April 2027. The intervention will be carried out in control centers, technical rooms and the more than 200 emergency exits, without affecting traffic except for specific outages to renew amplifiers.
Among the notable developments is the increase in FM stations, which now number 48 of the current 12. This will expand the ability of the M-30 Radio system to inform drivers of safety recommendations in the event of an emergency. “We have gone looking for the most modern thing on the market,” assures Bacon.
A broader technology plan. This renovation is part of a comprehensive modernization of the facilities that has already mobilized 34 million euros. Recent improvements include bluetooth beacons that allow maintaining the GPS signal inside the tunnels, in addition to a project for centralized management of the control center financed with Next Generation European funds.
