I think at this stage most of us here are familiar with the pattern of development on the island of Ireland. Practically all of the recent developments with the honorable exception of the improvements to the Derry line are focussed on the hubs of Belfast and Dublin. With that emphasis comes a misbalance of population and the continuing decline of the counties west of the Bann and the Shannon.
The Atlantic Economic Corridor proposals intend to change that way of thinking. If Ireland is to expand and consolidate growth rather than manage decline a new emphasis needs to be made to shift more development along an axis from Derry to Cork. This will involve more emphasis on linking the cities of the West and indeed the creation of one or more new cities.
Pie in the sky? Pipe dreams? Perhaps if you choose only to listen to the dead hand of the Civil Service and dead handed economists like Colm McCarthy et al. However more and more people are starting to imagine new ideas that could transform Ireland and how it works.
I have two links for you; the first link is a presentation by John Moran, Chief Executive of think tank RHH International http://nigeldugdale.ie/2016/10/10/no-one-shouted-stop-growth-cars-suburbia - this discusses how the West can be transformed into a genuine counterweight to the East.
The second is a report from the Irish Railway Developments blog on the launch of the Cicero Report on the better than forecast Limerick-Galway line passenger numbers. It includes extracts from speeches made by Michael Ring TD and Paddy McGuinness, Chairman of the Western Development Commission.
