Question to the Department for Transport:

To ask His Majesty's Government what is the latest design for the approach tunnels and grade separation works for the HS2 approaches to Euston; how many station platforms are they designed to accommodate; whether this design has received full safety approval and from whom; and whether they plan to place a copy of the plans in the Library of the House.

HS2 Ltd is responsible for designing and building the Euston Approaches. The Company is continuing to progress with the existing design for the approach tunnels and grade separation in line with the requisite technical, safety and environmental standards at all times. The design of the HS2 tunnels has been refined to minimise ground movement and settlement mitigation measures have been developed to be compatible with the operation of the existing railway. As set out on the Network North Command Paper the HS2 station at Euston will comprise 6 platforms which can accommodate the trains we will run to Birmingham and onwards.
