11,000 tonne tunnel is installed – A UK engineering first

A UK engineering first is set to take place as a huge 11,000-tonne curved concrete box is to be pushed under the East Coast Main Line (ECML). The structure, which weighs more than the Eiffel Tower, is being installed in a meticulous nine-day operation as part of the East Coast Upgrade.

Engineers spent the past nine months construction the tunnel next to the East Coast Main Line as trains have flown past between London and Edinburgh. The traditional way of installing a tunnel would involve closing it completely for a month, but the pre-constructed structure will be installed in just nine days and means a reduced level of service will be able to operate at the same time.
