Channel Tunnel Rail Link section 2: Stratford.

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]
