The recommended investment programme will cost €8.5 billion. It is clearly necessary to consider different ways of funding it, including public private partnerships and development levies. Iarnród Éireann is also considering how to process and progress the Cork rail feasibility study and I expect to hear from it shortly on that and other issues. It is anticipated that the investment under consideration will involve further upgrading of rail commuter services in the greater Dublin area, including: the provision of increased capacity on DART and out suburban services to Drogheda, Dundalk, Maynooth, Kildare and Arklow; improving the quality, journey times and frequency of all radial inter-city routes; upgrading rolling stock; additional improvements in reliability and safety; and improving station facilities.
