The transfer of responsibility was staged, with transfer of control of the London Underground delayed until July 2003, when London Underground Limited became an indirect subsidiary of TfL. Between 2000 and 2003, London Underground was reorganised in a Public-Private Partnership where private infrastructure companies (infracos) upgraded and maintained the railway. This was undertaken before control passed to TfL, who were opposed to the arrangement. One infraco went into administration in 2007 and TfL took over the responsibilities, TfL taking over the other in 2010.
