High Speed Two (HS2) is a new £56 billion ($67 billion) high speed (alignment for 400 km/hr) railway which will form a “spine” of a reshaped rail network providing an engine for growth and connecting eight out of the top ten regions within Great Britain. There are about 60km of twin bore (11 tunnels) and 11km of (17 tunnels) cut-and-cover tunnels along the HS2 route. This paper describes the various tunnels and the surface challenges (environmental, topography, existing infrastructure, route alignment restrictions, above ground third party asset requirements, integration to the existing rail network & transportation modes) which have dictated the use of underground solutions as well as the tunnel type, design and construction method.
