Case Study - Channel Tunnel Law, Engineering and Safety; Channel Tunnel Law and Engineering: Safety Regulatory rigour to be applied to modifications to safety systems

The first part of the presentation will include an introduction of the channel tunnel including the physical layout and key safety features together with an overview of the safety regulatory framework covering the role of the Inter-Governmental Commission (IGC) and the Channel Tunnel Safety Authority (CTSA). The current and future EU legislative arrangements will be considered together with their impact and interpretation in the context of the channel tunnel environment. The second part of the presentation will provide details of new modification arrangements which are currently being piloted relating to the degree of regulatory control over modifications to the safety critical systems in the tunnel. It is understood that the particular approach developed for the channel tunnel environment is being considered by the European Rail Agency (ERA) in connection with its work on common safety methods.
