Question to the Department for Transport:

To ask the Secretary of State for Transport, what the cost benefit ratio was of each major railway scheme authorised by the Government since 2010.

Benefit Cost Ratios are calculated at many points in time during the lifecycle of a project including to inform a number of specific decision points. Due to changes in appraisal guidance benefit cost ratios calculated at different points in time may not be directly comparable.

The benefit cost ratios for major rail projects with a value over £1bn and currently in delivery are set out in the table. These are based on the BCR at final business case stage or more recently published information where available. The benefit cost ratio of these and other rail schemes will have changed since these assessments were undertaken.
