Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the Answer of 20 May 2025 to Question 51729 on Railways: Electrification, when she plans to publish the whole-life costs for (a) full and (b) partial electrification for all rolling stock traction types.

Officials from the Department for Transport are working closely with Network Rail to produce their new 'Long-term Planning for Rail Decarbonisation' strategy, this strategy will include an examination of the whole life costs of each option to upgrade traction to set out a realistic, affordable, and deliverable approach to a net zero railway. We expect Network Rail to engage with industry as part of the development of this strategy and we expect to see a draft of this strategy before the end of this year.
