HS2 clears way for Old Oak Common tunnel crossover box

old oak common crossover box

High Speed 2 (HS2) promoter HS2 Ltd has cleared a key construction site close to the new Old Oak Common “super-hub” station.

The 42,000m² site is where HS2 will build the Victoria Road crossover box, a huge underground structure which will allow trains passing through the London tunnels to switch tracks.

HS2’s London enabling works contractor Costain/Skanska joint venture and subcontractor McGee, worked together to clear the site.

HS2 Ltd programme director Matthew Botelle said: “The Victoria Road Crossover Box will be a vital part of the underground infrastructure that will make Old Oak Common one of the best connected stations anywhere in the UK.”

Costain, Skanska and Strabag are in a joint venture called SCS Railways which will design and build the underground crossover box.

The 130m long box will be 25m underground, with three headhouses at ground level to provide maintenance and emergency access. A separate ancillary shaft will also be excavated.

During construction, the box will also be used to launch two of the four tunnel boring machines which will excvate the tunnels between Old Oak Common and Ruislip.

More than 6,500m³ of rubble from the clearance of the warehouses and light industrial units at the site was processed on site and is to be reused during construction of the tunnels and crossover box.

Excavated material from the tunnels will be removed by the box and taken away by rail from the project’s nearby Rail Logistics Hub.

The box may also be used to provide sustainable waste heat energy to hundreds of new homes around the site, as part of the wider Old Oak and Park Royal development.

Earlier this month, the Old Oak and Park Royal Development Corporation (OPDC) was given £250M to develop infrastructure at the Old Oak Common site.

The investment, from the government’s Housing Infrastructure Fund (HIF), will be put towards development of roads and utilities at the Old Oak North site, close to the transport hub which will connect HS2 and Crossrail.
