The power upgrade is essential so that we can run more new, sophisticated trains and new signalling
London Underground (LU) announced today that EDF Energy has been awarded a major contract for the second stage of the LU Sub-Surface Railway power upgrade.
It is anticipated that the three-year, multi-million pound contract will be completed by 2013, with the main focus of works relating to the Circle and District lines.
There will also be some works on the Metropolitan and Hammersmith & City lines.
Contract works will relate to the design, construction and commissioning of substation electrification upgrades at 20 locations and includes associated tunnel cabling and protection systems.
David Waboso, LU's Line Upgrades Director, said: 'About three-and-half million passengers use the Tube every weekday and this will increase in the future which is why we are upgrading the Underground network with larger modern stations and larger new trains.
'The power upgrade is essential so that we can run more new, sophisticated trains and new signalling.
'A fleet of 191 new air-conditioned walk-through trains will be coming on the sub-surface railway, with the first train in passenger service on the Metropolitan line from this summer.
'The first of the longer trains, with seven carriages instead of six, are scheduled to be delivered to London Underground in late 2011, before the fleet is introduced into service on the Circle and Hammersmith & City lines in 2012.
'The Sub-Surface lines cover over 300 km of track and serves around 40 per cent of the Tube network.
'The upgrade will deliver significant increases in capacity including 65 per cent on the Circle and Hammersmith & City lines, 24 per cent on the District line and 27 per cent on the Metropolitan line.'
Jean-Noel Reimeringer, EDF Energy's director of infrastructure services, said: 'EDF Energy is delighted to have been successful in winning this very important contract.
'Our experience and expertise in the rail industry has proved crucial.
'We will work closely with LU to ensure an even better service for passengers.'
