Engineering Challenges of Linking into Europe

Anglo-French agreement to proceed with construction of the Channel Tunnel was formally finalized in 1987. The Usage Agreement allocated 50 per cent of Tunnel capacity for operating through international freight and passenger services. This paper investigates the varied technical and cultural challenges involved in linking into the European high-speed rail network. TMST Nightstock and Class 92 projects are described as examples of how differing standards and practices in design, maintenance and commissioning of these trains have been reconciled.
