Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate he has made of the date on which the first UK trains will be converted to run on hydrogen.

Alstom have recently proposed a trial of trains converted to run on hydrogen in the North in association with Eversholt and Arriva Rail North and will need to develop a business case accordingly. The target date for these trains entering service will be dependent on both the business case and on the regulatory approvals being given.
