Under the National Development Plan covering the period 1994 to 1999 total investment in the mainline rail network will amount to approximately £275 million. This investment will be focused on track renewal, £123 million, modern signalling systems, £27 million, and rolling stock, £125 million, in accordance with the overall policy framework set out in the Operational Programme for Transport. All major lines in the inter-urban mainline railway network, including the Dublin-Sligo line, are included in the proposed investment programme. It is too early to give the precise details of individual investments on particular lines. This will depend on the outcome of detailed consultations expected to take place with the EU Commission in the months ahead.
