1.6 The Department for Transport (the Department) and Transport for London (TfL) jointly sponsor and oversee the Crossrail programme. Crossrail Ltd is a company wholly owned by TfL and is responsible for delivering the programme safely to cost and schedule. The project development agreement sets out sponsors' high-level requirements for Crossrail, such as service frequency and service levels, as well as the programme's governance and delivery structure (see Figure 2).
1.7 The Department and TfL jointly fund the programme. The overall amount of available funding has changed over time. Figure 3 on page 14 shows the main sources of funding for the programme and how they have changed over time. The funding for Crossrail does not include the cost to build and maintain trains and a maintenance depot, which amounts to an upfront capital cost of around £1 billion, funded by TfL.
1.8 Throughout 2018, the programme began showing signs of distress, until eventually it became clear that the programme could not be delivered as planned. In a written ministerial statement in July 2018, the government announced that a further £590 million would be made available to address cost pressures on the programme. This was followed shortly after by Crossrail Ltd's announcement in August 2018 that it would not be able to open the central section of the railway in December 2018 as planned.
1.9 In response, sponsors commissioned a series of reviews by KPMG into the finance and commercial position and governance of the programme. In December 2018, the emerging findings of the finance and commercial review stated that up to an estimated £2 billion of additional funding would be needed to complete the railway, based on a high-level assessment of Crossrail's management information. In the same month, Crossrail Ltd announced that it could not commit to an opening date for the railway at that time.

1.10 The Committee of Public Accounts took evidence on the delivery of the Crossrail programme in March 2019. The Committee questioned the Department and Crossrail Ltd on the warning signs that the programme was not delivering to plan, what actions the sponsors took to intervene in the programme, the causes of the cost increases and delays, and the risks of further funding for the programme being required.
