Whether or not global warming/climate change is a thing, the maxim of the late Noel Carroll of Dublin Corporation about people who live near water should expect to get their feet wet occasionally applies.
The Irish Independent is reporting delays on the DART line today due to a high tide causing flooding on the line at Blackrock.
The Dublin & Kingstown Railway (from modern day Pearse Station to Dun Laoghaire) runs along/near the coast for about 60% of its length – from Merrion Gates to Dun Laoghaire.
This makes the line susceptible to such events and if rising sea levels become a thing, this line won’t be a thing. What is the State doing about this (apart from putting levies on drinks containers)? Nothing, from what I can see, but a State that plans to electrify a railway line and stop the electrification less than 1 mile from the next station is not one which displays competence in the area of planning.
Not everyone lives in the now – this site posted a series of posts three years ago on this very issue. I link to the post about the DART line south of Sydney Parade. The post is as relevant today as it was then.
