New designs for HS2 London Euston station

Two brand-new images have been released showing the concept design for the exterior and interior of the new HS2 station at London Euston.  The designs, updated from 2015, are based on a less complex, more efficient, ten-platform station which can now be built in a single stage. They have been drawn up by a design consortium made up of Arup, WSP and Grimshaw Architects, working into HS2’s Station Construction Partner, Mace Dragados JV (MDJV). (more…)

First concrete segments cast for HS2’s Colne Valley Viaduct

Work on the UK’s longest railway bridge has ramped up this week, with High Speed Rail Group members Align JV beginning production of 1,000 enormous concrete segments that will form the deck of the Colne Valley Viaduct.

The viaduct will carry high-speed trains some 3.4km across a series of lakes and waterways just outside London, with the design inspired by the flight of a stone skipping across the water. The design was chosen to enable views across the landscape, minimise the viaduct’s footprint on the lakes and help complement views across the natural surroundings.

The huge deck segments – which weigh up to 140t – are being made on site at a temporary factory built specifically for the project. Each segment will be a slightly different shape depending on where it fits into the viaduct, a modular approach chosen to ensure quality, safety and efficiency in production and to avoid having to transport the segments by road.

HS2 Ltd is on track to cut the amount of embedded carbon in the viaduct by at least 28.4%. Applying lessons from the construction of the latest European high speed railway (more…)

Images of HS2 Green Tunnels released

HS2 Ltd has released some of the first images of the longest of three innovative ‘green tunnels’ that will be built across Buckinghamshire and Northamptonshire to help blend the new high-speed rail line into the landscape and reduce disruption for residents.
