The RPA estimates that the metro for Dublin would cost €10 billion –€13 billion if the extension mentioned in the strategic report was included. We know this type of money is not available. We will have to decide where our priorities lie, which might mean examining the feasibility of those lines beside which large populations do not reside and investing resources in population growth areas instead. With this in mind, the Minister will have to examine how Dublin is growing. I was delighted to hear him say that county councils would have to examine land use, by which I presume he means rezoning, and that, if railways were to be built, they would have to serve proper populations.
