📋 Tender Overview
The message no mobile coverage will be a thing of the past in an HSL tunnel between Breda and Rotterdam. KPN T-Mobile and Vodafone have worked hard in recent months on mobile coverage in the Tunnel Oude Maas. This makes this the first tunnel on the high-speed line HSL with a mobile network. ProRail and Infraspeed facilitated the construction of mobile installations in the tunnel during the major shutdown last November.A complex jobThe construction of mobile installations in HSL tunnels requires special mounting technology because trains run very fast. The systems must withstand the pressure created at speeds of 300 km h. That is why wind tunnel tests have been carried out with the antennas and extra well-protected cabinets have been developed for technical equipment. Partly because it is such a complex job preparations for this project have been running since 2017.First HSL tunnel with coverageDue to the many tunnels on the line the mobile coverage on the HSL is lost. And that is annoying because it is precisely on the train that travelers enjoy doing something for work or watching a movie. That is why the mobile operators will gradually realize mobile coverage in the various HSL tunnels.The aim is to provide all five HSL tunnels with a mobile network by mid-2023 including the seven-kilometer-long Groene Hart Tunnel. The experience gained during the work in the Tunnel Oude Maas will be used to provide the other HSL tunnels more quickly in the future. In the coming weeks the network will be intensively monitored and optimized even further.
