Question to the Department for Transport:

To ask His Majesty's Government what is the latest design for the route of the tunnels from Old Oak Common to Euston, and whether they will place in the Library of the House plans showing that route, alignment and gradients.

The route and alignment of the HS2 tunnels from Old Oak Common to Euston are bound by the High Speed Rail (London – West Midlands) Act 2017. HS2 Ltd is responsible for designing and constructing the tunnels and grade separation and is continuing to progress with the current design ensuring compliance with all requisite technical, safety, and environmental standards. The design has been refined to minimise ground movement, and settlement mitigation measures have been developed to ensure compatibility with the operation of the existing railway.

The alignment remains materially unchanged and is publicly available on the HS2 website.

The alignment immediately approaching and within Euston Station will be subject to the finalisation of the station.
