The pressure variations which the passengers may have to withstand as vehicles run through tunnels are a function, mainly, of the running speed, of the cross-sectional area, length and aerodynamic shape of the trainset, and the tunnel length and cross-sectional area.

3.2.6. main design features such as watertight bulkheads, air escapes, etc., above and below the bulkhead deck that can result in asymmetric flooding should be modelled properly as far as practicable to represent the real situation; Ventilating and cross-flooding arrangements should be constructed to a minimum cross section of 500 mm2;

part of a water catchment area from the source(s) to a natural or artificial barrier that prevents the upward migration of aquatic animals from lower stretches of the water catchment area;

Preparatory action is underway involving feasibility studies and pilot projects costing 22 million ecus in the domains of EURO-ISDN (Integrated Service Digital Network, involving health care, teleworking, education, applications for small and medium-sized enterprises and desktop/multimedia services. Following a mandate from the Essen European Council in December last year, the Commission has established a high level group to define the criteria for the setting up of environmental networks. The idea is for member states to join in developing projects of common interest for environmental protection or improvement such as waste management o ...[+++]r water policy. In terms of the transport networks, assessing the progress of the 14 priority projects is complicated by the fact that these are long-term infrastructure projects, necessarily cross-border: it may be that there is substantial progress in one section of a project and no action elsewhere. Establishing the proper legal framework for the TENs has been greatly hampered by disagreement between Member States and the European Parliament as to whether to include the priority projects as agreed at Essen and an article on the need for environmental assessments - to which the Commission is committed. Of greater long term concern to the Commission is the perceived reluctance of national governments to adapt their national priorities to building the TENs network. While welcoming the potential benefits - competitiveness, job creation and economic cohesion - many countries behave as if construction and funding are the job of someone else. This is reflected in terms of slow progress in defining projects (eg. the Munich-Verona ie.Brenner), conflicting scheduling on the part of national authorities either side of a border (eg. PBKAL, HST-East), failure to resolve financing questions (eg PBKAL, Brenner, HST-East) and inability to from multinational project authorities to co- ordinate work on projects (eg. PBKAL, Brenner).

We hope the new legislation resolves that by cutting these truly unreasonable-for-navigation sections of water out.
