Discovery Channel Documentaries - King's of Construction: Gotthard Base Tunnel (Switzerland)

Seizoen: 2011 - Aflevering: 21 / 678 - Eerst uitgezonden: 17 augustus 2011 - Episode ID: 563941

The Gotthard Base Tunnel is actually two main parallel tunnels measuring a record-breaking 57km each, served by a maze of access tunnels, shafts and passages. In total there will be 153.5 km of tunnel through the Swiss Alps. The project has been conceived to solve the problem of heavy European road traffic on this major route through the Alps, while simultaneously developing Europe’s high-speed rail network. The existing tunnel, much higher up, can only handle three-truck freight trains of up to 2,000 tons. The new tunnel will take 4,000 ton heavy freight trains – carrying entire trucks on board - effortlessly through the heart of the mountains. Passenger trains will be able to travel at speeds of up to 250kmph, resulting in a train journey time between Zurich and Milan of just two hours and 40 minutes – a third less than at present.
