Question to the Department for Transport:
To ask His Majesty's Government what is the height above track for the emergency escape walkways in tunnels for Phase 1 of HS2.

In general, the height of the evacuation walkway in HS2 tunnels is 760mm above top of rail. For some specific locations due to track gradient and drainage constraints there is some small variability in this figure.
