by Metronet had yet to be seen — "We were supposed to be getting private sector expertise and technology with the PPP (Public Private Partnership) but instead they are just using the same old kit." A week later the chief executive of Metronet was sacked, after complaints that it had made £50million profit despite being behind on all its major works. By April 2005, it had started work on only 13 station refurbishments, instead of 32 as scheduled, and was more than a year behind on the refurbishment of 78 District line trains. It was also behind on its track replacement programme, having completed 28 km of the anticipated 48 km. In November 2006, Metronet were heavily criticised by the arbiter of the PPP, the Office of Rail Regulation (ORR) over their performance from 2003 to 2006. Analysis included criticism that Metronet had not performed in an economic or efficient manner, and had failed to follow good industry practice. The ORR also stated that Metronet would be held responsible for £750million in cost overruns. The other PPP consortium, Tube Lines, noted that they were delivering projects on time and on budget. In July 2007, Metronet admitted that it may have caused a Central Line train derailment near Mile End, in which a train hit a fire blanket left by maintenance workers. Administration In April 2007, Mayor Ken Livingstone stated that Metronet could collapse due to a £750million overspend. In July 2007 it was reported that Metronet was "teetering on the brink of administration". The situation arose because it had received only £121million out of the £551million it needed to cover cost over-runs. By contrast, Tube Lines, the other PPP consortium, had brought in almost all of its works on time and on budget. On 18 July 2007, the company was placed into administration. To enable its business activities to be kept going while the winding-up of the company was in progress, the UK Government provided Metronet with £2billion in 2008. Following negotiations with Bombardier, Metronet modified contracts to allow for continued delivery of 2009 Stock and S Stock trains, while releasing Bombardier from its obligation to resignal the sub-surface lines. Aftermath On 27 May 2008, Metronet came out of administration, and its contracts and employees were transferred to TfL under two new temporary companies, LUL Nominee BCV Ltd and LUL Nominee SSL Ltd. On 3 December 2009, the PPP business
