The contingency provision of £500 million in the national development plan is in respect of the longer term development of the suburban rail network and the underground section of Luas. Among the options for the future development of the suburban rail network being evaluated by Ove Arup from a feasibility and cost perspective as part of the strategic rail study are a new inland rail link to Navan. Also included is the separation of long distance and commuter rail traffic through the construction of bypass rail lines, including a new rail link from the Belfast line through Swords and Dublin Airport to the western lines and a new rail link east of the loop line in Dublin city centre. Other options are the quadrupling of existing double lines where feasible and the provision of enhancement of rail services to the development centres identified by the strategic planning guidelines. Phase one centres include Drogheda, Naas/Newbridge/Kilcullen, Wicklow and Navan, and phase two centres include Athy, Arklow, Kildare and Monasterevin. Another option is more sophisticated signalling technology to increase track capacity.
The strategic rail study will be completed during January. Only then will it be clear what specific projects are being proposed for implementation as part of the longer term suburban rail development programme. Not all the options will necessarily be recommended and some may be mutually exclusive. The £500 million contingency is a significant sum of money. However, I assure the Deputy that, if further resources are required at a later stage, they will be provided. My priority now is to spend the contingency fund which has been set aside and to spend it well.
Regarding Luas, geotechnical studies of the proposed underground section in the city centre are taking place and the results of those will be available by the end of the year. It should be borne in mind that all the projects just mentioned are medium to long-term projects and that the national development plan provides for funding up to 2006.
