I note RUI
estimated DT+Oranmore at 50m Euro in Nov 2007. (In Frank Dawson's
WRC PowerPoint dream world it seems more like 21m (12 Galway-Oranmore, 9 Oranmore-Athenry)
No doubt IE are doing their usual - adding in stuff like closing LCs, building new overbridges and tinkering with the gradients as on the Midleton line rather than simply costing the relocation of the existing track from the centre of the alignment, the installation of the second and the revised signalling to include provision at Athenry for Tuam. Not to say that that wouldn't be a good idea, just that it could have been broken out better.
That said, there's a big difference between the Ennis-Athenry project, done on an unused track with no bustitution or other disruption costs, and tearing up a live railway. You can't simply use the same cost/km figures, as the local politicos have done, for an intercity railway as opposed to the 35mph average speed cattletrack from Athenry to Ennis.
