Date: 26 Apr 2012 • Issue: High Resilience Tunnel Communications – Cornerstone of safe operations and connected passengers

Although they are largely hidden from public view, tunnels are an engineering wonder of the modern world. From Japan’s Seikan tunnel to EuroTunnel, the Channel Tunnel between Britain and France and Switzerland’s Gotthard, advances in tunneling techniques have allowed engineers to push deeper and further beneath the surface, through even the most difficult ground conditions, to build these transformational transport links. This issue of TrackTalk focuses on how the latest telecommunications systems can enhance tunnel operations and allow nonstop connected passengers, bringing together four distinguished perspectives on this topic from industry experts.

Social View: Going underground

Rail tunnels are vital to the functioning of modern cities, and recent advances are helping to improve both their construction and operation. TrackTalk considers the role technology is playing in building and running better tunnels.

Customer View: EuroTunnel – Flexible communications beneath the seafloor

After almost 20 years of operation, Eurotunnel is renewing its telecommunications infrastructure in a program that will enhance interoperability and provide on-board connectivity for passengers. TrackTalk looks at how Eurotunnel developed a business case for the replacement of these vital assets, and how the project is being delivered.

Customer View: AlpTansit Gotthard – The role of telecommunications technologies in tunnels

The Gotthard Base Tunnel will be the world’s longest rail tunnel when it opens in 2016, and it is also set to be one of the most advanced. Operational, communications and safety systems in the tunnel are highly automated, and they all require comprehensive and efficient telecommunications infrastructure. TrackTalk considers how highly-automated communications will ensure the railway runs safely and reliably many kilometers underground.

Expert View: Guaranteeing success in the world’s longest tunnel

Communications play a critical role in the most technically-advanced railway tunnels, from the construction phase through to commissioning and commercial operation. And in tunnels, where existing telecoms infrastructure is reaching life expiry, the application of new technologies can unlock opportunities for innovative services and additional revenue streams, such as 3G connectivity for passengers.

With its technical know-how and experience in systems integration, Alcatel-Lucent is implementing some of the most important and innovative tunnel communications projects in the world. As we discover, whether constructor or operator, finding the right communications partner is crucial to underground success.
