In 1999, before control was passed to TfL, London Underground was split up so that a public–private partnership (PPP) arrangement could be put in place, with London Underground remaining a public company running the trains while private companies were responsible for upgrading the railway. Three packages of 30-year franchises were drawn up, covering the Jubilee, Northern and Piccadilly lines (JNP), the Bakerloo, Central Victoria and Waterloo and City lines (BCV) and the sub-surface lines, the Metropolitan, District, Circle, East London and Hammersmith & City lines (SSL). In 2003 the BCV and SSL contracts were won by Metronet (a consortium of Balfour Beatty, WS Atkins, Bombardier, EDF Energy and Thames Water), while JNP was won by Tube Lines; these were known as the "infracos" (infrastructure companies). In 2000 overall control of the system passed to TfL, which had been opposed to the arrangement. Metronet went into administration in 2007, and TfL took over responsibilities, and TfL also took over Tube Lines in 2010.
