Well, all of Europe except Malta, the Balearics, Sardinia, Crete, Cyprus, Dodecanese, the Hebrides, Orkney, Shetland, the Friesian islands, ....
I agree that there might have been some sense in using the boring machines on another project. (Just not this one!)
And which bit of Wales? Holyhead to Kilkeel? Abergwaun to Wexford (of course, that wouldn't fit the NI bit)?
That boring machine wouldn’t work. It’s too busy on here.
And yes. The Wexford link up would be the most sensible.
