Question to the Department for Transport:

To ask the Secretary of State for Transport, if he will publish the costs associated with reducing the planned number of HS2 platforms at Euston Station from 11 to 10.

The Department for Transport and HS2 Ltd are continuing to investigate whether building the HS2 station in a single phase would speed up delivery and reduce the overall cost. Work to assess the impact of the proposed design changes to the HS2 Euston Station are ongoing. Initial HS2 Ltd analysis indicates that moving to a slightly smaller HS2 station at Euston maintains the station infrastructure capacity to run all of the services in the planned HS2 Phase 2b Train Service Specification. A final impact assessment is expected in Spring 2021.
