That is fair enough. Over the years, the Luas has been a real success story. We would all like to have an underground or a metro. In the short term it is a case of ensuring we put on a sufficient number of services in the city and where it matters, if we are talking about connectivity with the airport and everything. Sometimes people can believe it is too difficult. People say they would like there to be a Luas line, an underground or whatever but if we put enough effort into a really good service we can shorten that gap. Is that something the NTA has considered?
