Question to the Department for Transport:

To ask His Majesty's Government, following the cancellation of much of the HS2 project, whether they will review the design and procurement of the rolling stock to be used on HS2, such that all commissioned new train sets will be able to continue on to the existing rail network.

The Hitachi-Alstom joint venture is contracted to manufacture and maintain the HS2 rolling stock for Phase 1 of the project. We will complete Phase 1 of HS2 between Birmingham and London, with a rescoped Euston station. The contracted HS2 trains are designed to be capable of operating on both the existing rail network and new High Speed Rail network. As such a review of network interoperability is not required.
