COMLAB Equips New Railway Line with TETRA BOS Communication System
The COMLAB system has been chosen because of the company's many years' experience in tunnel communication systems involving different components and in the development of complete systems that enjoy an excellent reputation worldwide.
A new railway line for Intercity Express (ICE) trains is now being built in Germany between Nuremberg and Berlin. It is known as the German Unity Transport Project 8 (VDE 8) and totals 515 km.
For this new line, COMLAB is supplying the digital system components of the network required for German police, fire and other officials (BOS). This involves providing a reliable and redundant communications distribution system based on fibre-optics that meets all requirements of public safety officials and the German Railway. The system components must also meet requirements of the different German states and be certified by the German Federal Railway Office (EBA).The COMLAB system has been chosen because of the company's many years' experience in tunnel communication systems involving different components and in the development of complete systems that enjoy an excellent reputation worldwide.
Within VDE 8, sub-project VDE 8.1 covers the roughly 106-km line section between Nuremberg and Erfurt. This section involves the construction of 22 tunnels totaling 41 km that are being equipped with TETRA BOS tunnel communication systems. From a functional viewpoint, these systems are an extension into the tunnels of the TETRA BOS digital communication network. This means technical, physical and organisational dependencies between the TETRA BOS communication systems in the tunnels and those in the open air. The nature of these dependencies in turn depends on how the systems are integrated within the larger TETRA BOS digital communication network.
