The western rail corridor is the term applied to the Sligo-Cork and the Galway-Cork rail proposals. The rail corridor was identified by the consultants as fitting in particularly well with the aims of the national spatial strategy. However, the review concludes that the proposals could only become viable if the relevant planning authorities incorporated the proposals into regional, county and local development plans and land use and transportation strategies. The viability of any rail project is critically dependent on it being supported by the adoption of suitable complementary land use and transport policies, otherwise there would not be the basis of developing sufficient rail demand to justify the very significant investment involved. These are the critical prerequisites that would first have to be taken before a detailed feasibility study could be undertaken. The appropriate decisions are ones to be considered closely at regional and local level.
