2.2 Crossrail Ltd's current forecast cost of the Crossrail programme, excluding trains and depot but including Network Rail's works on the existing network and a provision to cover assessed risks, is just over £17 billion. This is around £2.2 billion more than the £14.8 billion of funding agreed by sponsors in 2010, and £600 million less than the current level of agreed funding of £17.6 billion.
