Question to the Department for Transport:

To ask the Secretary of State for Transport, with reference to page 6 of Sir Peter Hendy's report on the replanning of Network Rail's Investment Programme, published on 25 November 2015, if he will publish an analysis by cost heading of the £2.8 billion estimate of the cost of Great Western Main Line electrification.

As the Sir Peter Hendy report states, ‘work to update the programme for Great Western Electrification is being concluded as this report is completed. The latest estimates for cost and delivery milestones have been reflected in this report although this is still subject to final review. Electrification to Cardiff is planned to be completed in Control Period 5 (2014-19) within the estimated total cost of £2.8 billion (in 2012-13 prices). As elements of the design programme mature, a more accurate assessment of the cost and delivery schedule will be established.
