Limerick Galway is not going to work, note the press release makes no reference to that
Limerick commuter and Galway commuter could work if done correctly and in Galway, Oranmore Galway would be faster by rail since it takes a direct route through the main suburbs. You then end up with Limerick Galway as a secondary outcome. We are rightly concerned that IE will make a mess of it. The time has not arrived yet where it makes sense, we are not objecting to it. We will have to wait till IE come back with the actual plan to make a definitive judgement.
The press release if I remember correctly refers to the opening of the full WRC Cullen's announcement also included reference to Tuam and beyond which is clearly a non starter
