Concrete paving through the Channel Tunnel Rail Link’s tunnels under London is now complete.
The last section of concrete paving required within the tunnels, was laid on Friday, 22 October 2004. The entire paving job for the 22 miles of tunnels took only 225 days to complete and used 98,000 cubic metres of concrete.
CTRL’s tunnels run between King’s Cross and Dagenham. Two parallel tunnels each carry a single track on which trains will run at up to 143 mph. The tunnel bores were completed in March 2004.
Three separate paving operations were required in each tunnel to form the concrete track bed on which sleepers and rails will be laid with a walkway on either side. Next comes the installation of track, overhead power, signalling and communications systems.
