The last stop before London on the Channel Tunnel Rail Link—now called High Speed 1—is Stratford International in the heart of the London 2012 Olympic park. This paper describes the design and construction of the station box, a 1 km long, and up to 55m wide and 26 m deep, open concrete structure. It initially served as the construction and portal site for four of the London tunnel drives on section 2 and now provides the location for the Stratford International station and major track junctions. Excavated material from both the tunnels and the box has been used to regenerate the old railway freight yards into a site for a major new development. [ABSTRACT FROM AUTHOR]

Section 2 of the Channel Tunnel Rail Link—now known as High Speed 1—emerges from tunnels at the north-east corner of King's Cross lands in London and then sweeps across into St Pancras station at the south west. This paper reports on the major rail network that has been constructed in 'area 100' to enable train services to approach the extended St Pancras station, and also interconnect with other railway networks, thus facilitating high-speed rail services north of London. It describes the engineering objectives and the civil and railway construction works needed to achieve this complex railway network. [ABSTRACT FROM AUTHOR]

The London tunnels of section 2 of the Channel Tunnel Rail Link—now known as High Speed 1—carry the new railway from the eastern edge of London into the centre at St Pancras, a distance of approximately 20 km. The scheme required civil engineering and particularly mechanised tunnelling to be pushed to the limits of technology. Successful delivery of the works required strong emphasis on proactive risk management and a single team approach throughout the design and construction phases. This in turn led to an unusual but effective procurement approach. Together these factors have resulted in the successful delivery of a major new transport asset with little disruption to the everyday life of Londoners. [ABSTRACT FROM AUTHOR]
