After almost a week in Vienna recently, I saw a city some 25% larger than Dublin with seamless, and in some cases 24 hour, tram, bus and underground railway lines. We have two tram lines, the red one not being all that speedy ("luas"?!) and Vienna has 177km of trams. There are some 6 or 8 separate underground lines covering all areas; we have none. Buses almost seem superfluous, and nobody ever takes their car into town. There's absolutely no need. Our roads are choked with buses and cars.
Dublin's population will exceed that of Northern Ireland, i.e. will be 20% larger, within 15 years. this will make it equal to Vienna's. We NEED a system like this, and for that matter it might be of interest to readers to know that drivers of trains, trams and buses in Vienna - where the cost of living is almost exactly the same as Dublin - earn some 65% of what they earn here. Just sayin'.
Against this background, and doubtless many others like it, all this fuss about one tunnel is just pathetic.
Oh yes; Austria has a similiar number of taxpayers to Ireland.
