Earlier I referred to the UK electrification fiasco. There is a really good article in Rail Engineer ("Getting Electrification Right") which should be compulsory reading for anyone looking at the future of rail development in Irland: See https://www.railengineer.co.uk/2018/...ication-right/
Earlier I also said go to the Continent rather than the UK for advice. Correction I should have said anywhere but England. From the Rail Engineer article it would seem that the Scots have done things properly, with huge cost savings.
