History was made deep below London as National Grid?s flagship project to help keep the lights on in London took one step closer to completion. Massive tunnel boring machine (TBM) Evelyn reached a pre-prepared tunnel shaft at St John?s Wood on Thursday, February 7.
Operated by a team of highly trained engineers who sit within her 100-m long structure, Evelyn is digging 19 km of the new 32-km electricity superhighway which National Grid is constructing deep below London.
Backed up by a support team of engineers above ground, Evelyn has so far dug 7.26 km of the tunnel, since beginning her epic mission in early 2012. The next phase of tunneling operations will see Evelyn journey toward Wimbledon, from Wandsworth.
A second TBM, Cleopatra, is carving out the other 13 km of the route and is due to arrive at St John?s Wood later this year.
National Grid?s Head of Cable Tunnels David Luetchford said: ?This week?s breakthrough is a dramatic illustration of how National Grid plays its part in connecting people to the energy they use. It?s nice to think that as Londoners go about their business Evelyn, Cleopatra and our engineers are at work deep underground helping to make sure that the capital?s future energy needs are met.?
The project is due for completion in 2018 and once operational it will play a vital part in delivering energy supplies to London.
