The existing DART fleet comprises 80 vehicles. Under the Operational Programme for Transport 1994-1999 65% EU funding was secured for the acquisition of an additional ten DART carriages. Two of these have recently been delivered while the remaining eight will be delivered in tranches of two by the end of February. As a result of the reallocation of Luas funding in 1998 an additional order for 16 DART carriages is being co-funded by the EU and the Exchequer. These carriages will be delivered in the autumn. The total fleet will then be 106.
Furthermore, the national development plan 2000-06 has made provision for the purchase of a further 46 DART cars.
The present DART extends from Howth to Bray, a distance of 38 km. The extensions to Greystones and Malahide will add seven kilometres at either end bringing the overall length to 52 km. The ratio of carriages per kilometre will decrease slightly from 2.11 to 2.04. However, this may not be the most appropriate yardstick for comparison purposes for a variety of reasons: while the length of the DART will be extended by 14km or 37%, only three additional stations will be added to the existing 26 stations;the catchment areas for the new DART stations will include existing suburban rail passengers from Malahide and passengers who at present drive to Bray; it does not adequately reflect the real increase in DART capacity of 32.5%. This will be further significantly increased over the period of the national development plan through the acquisition of the additional 46 DART cars and infrastructural works, including the extension of station platforms to accommodate eight car DART and increased city centre capacity. When that investment has been completed, peak DART capacity will be almost twice what it was at the end of 1999.
The current passenger carryings are approximately 20 million per annum. In recent years the rate of growth has been of the order of 5%-6% per annum and this rate of growth is projected to continue for the foreseeable future. The Malahide and Greystones extensions will clearly give rise to some additional patronage. However, it is not possible to predict this exactly because of a likely diversion of existing passengers who currently drive to Bray to board the DART or take diesel trains from Malahide.
