The construction: Technical facilities

Betriebszentrale mit Containerkollektiv

Operations centres and local control centres

There are a total of 12 operations centres housing tech-nical installations along the base route between Frutigen and Raron. All operations centres are constructed in pairs for security reasons, with one each in the eastern and western tunnels, so that each tube is capable of being operated independently. The operations centres in the tunnels equipped with cranes have all the equipment necessary to supply current to the trains and infrastructure as well as wireless communications transmitters, signal towers and air conditioning in a total of 136 containers. The operations centres are unmanned and are monitored and controlled from the operational control room in Spiez (DOLS) via the two local control centres (VOLS) in Frutigen and Raron.

Connecting tunnels

The 108 connecting tunnels that connect the two tunnel tubes serve as escape routes and also house a total of 1450 cabinets. These contain installations for electricity supply, maintenance and emergency lighting, data transmission, door control, and safety and wireless communications installations.

Ferden emergency stop

There is an emergency stop in each of the tunnel tubes in Ferden. They are connected by a ventilated emergency escape tunnel. The emergency stop is the escape and evacuation location for passengers in the event of an emergency. It is equipped with a fresh air supply, smoke extraction, communication systems, video surveillance and more powerful lighting.

Mitholz service stop

There is a service stop at the base in Mitholz, which can also be used to evacuate trains.
