In April 2005, Bob Kiley pressed for an urgent review of the PPP, describing its performance as "bordering on disaster". A week later the chief executive of Metronet was sacked, after complaints that it had made £50m 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 instead of the scheduled 48 km.
