7 We examined a range of other documents, including the evidence and findings of the Transport Select Committee's November 2006 report on Passenger Rail Franchising, the Department's July 2007 White Paper, Delivering a sustainable railway, and the research publications of Passenger Focus. In addition, we met the following stakeholders:
■ the head of the HM Treasury spending team on transport issues;
■ the chairs of Passenger Focus and London Travelwatch;
■ senior management from the established UK Rail companies: Arriva, Govia, FirstGroup, Virgin Trains, National Express and Stagecoach, to ascertain their views on the Department's approach to procuring and monitoring franchises;
■ David Quarmby, formerly SRA Chair, and Pen Kent, formerly of the SRA's audit committee, to identify changes from the SRA's approach;
■ The rail liaison officer for Transport for London (TfL), to understand TFL's franchising approach for London Overground;
■ the head of the Association of Train Operating Companies, to obtain a broader industry perspective; and
■ representatives of Network Rail and the Office of Rail Regulation.
