Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate he has made of the cost of full electrification of the UK's railways and the removal of all diesel powered rolling stock.

In ‘Decarbonising Transport: a Better, Cleaner Britain’, the government has committed to delivering an ambitious, sustainable, and cost-effective programme of electrification, alongside deployment of battery and hydrogen trains, guided by the Network Rail-led Traction Decarbonisation Network Strategy.

Electrification costs can vary significantly depending on factors that include complexity and geography. We will continue to ensure that new schemes deliver value for money for taxpayers.
