Working in partnership with London Underground, Metronet has taken over responsibility for upgrading, replacing and maintaining nine of the twelve lines on the entire network and will spend £17 billion during its 30-year contract. Some £7 billion of this will be spent during the first 7.5 years , on new trains, new track, new signalling and refurbished and modernised stations.
Metronet's shareholders consist of five world-class companies: Atkins, Balfour Beatty, Bombardier, EDF Energy, and RWE Thames Water. Metronet's business has a staff of some 5,000 people.
