I have just spent an hour in a pub listening to people whingeing about traffic issues in Laois and wondering if they've been to England in this century.
My place in England is in a one-horse town in the arse-end of nowhere and I have never suffered congestion, obstruction and general difficulties in driving anywhere near that in the Republic. The roadworks near my house there are a quarter of the way into their ninth year now, with no end in sight. Some roadworks in Wales ended this year - after 23 years - so we may need to be patient.
Goods traffic on rail will always be problematic in a small sparsely populated country with no large inland centres. If you have to load stuff onto trucks to get it to the railhead, and then offload it into trucks again, to move on to the final destination, then, on a small island, you will need to look at the numbers carefully to see if it's even worth the bother, or just leave it in the trucks and drive them all the way there.
