Spotlight: Giants underground (January 2003)

Channel Tunnel Rail Link – HOCHTIEF connects Europe

40 kilometers south of London, the River Thames is being undercrossed by two parallel single-track rail tunnels 2.5 kilometers in length. They form part of the first new rail route to be built in the United Kingdom for more than a century. And HOCHTIEF is involved.

“The world underground is always fascinating but what is really exciting is working under water”, says HOCHTIEF project manager Andreas Tauschinger. Three HOCHTIEF units are cooperating in the Channel Tunnel Rail Link project – working hand in hand 45 meters under the Thames. And they are very successful: the hole-through for the first tube took place two weeks ahead of schedule.

The first high-speed trains between the historic capital cities Paris and London will be able to use the tunnel as early as 2004. This will bring Britain a lot closer to the European mainland – where three other tunnels are currently also making headway. For example in Switzerland, where HOCHTIEF is helping to build the world’s longest rail tunnel.

The CTRL links the UK and France.
The Thames is undercrossed at a depth of up to 45 m.
TBMs clear the way ahead.
