Metronet signed the £17bn public private partnership (PPP) contract to upgrade London Underground's Bakerloo, Victoria, Central, District, Metropolitan, Circle and Waterloo & City lines last Friday.
Metronet comprises Balfour Beatty, Atkins, Thames Water, Seeboard and Bombardier and is now responsible for infrastructure maintenance, renewals and upgrades on the lines for the next 30 years.
The consortium plans to replace 185km of track and 166 points and crossings in the first seven and a half years. It will also upgrade 4,800 bridges, 1600 structures, 130km of tunnels, 155km of embankments and 225km of track drainage over the first 15 years.
Stations will also be refurbished, signalling replaced and new trains ordered. The first new trains will appear on the Victoria and Metropolitan lines by 2009.
