THE HS2 rail link has completed its biggest demolition challenge to date, clearing a key construction site close to the new Old Oak Common ‘super-hub’ station.

The site, equivalent to the size of six football pitches,  is where HS2 will build the Victoria Road Crossover Box, a huge underground structure designed to allow trains passing through the London tunnels to switch tracks.

Clearance of the site involved the careful demolition of eight separate buildings, with more than 98% of materials sent for re-use and recycling.

During construction, the caterpillar-shaped crossover box will also be used to launch two of the four boring machines digging the tunnels from Old Oak Common to Ruislip.

Once complete, the Victoria Road box could also be used to provide sustainable waste heat energy to hundreds of new homes around the site.
