The Minister is considering the possibility of the metro to the airport. I agree with Senator Norris that the suggestion about the metro should probably have been looked at more closely in the initial stages, but the reality is that we now have Luas. We are looking at the route to the airport and in my opinion this would provide a properly integrated solution to providing a modern efficient service to the hugely increasing numbers using Dublin Airport. It is estimated that by 2015 up to 30 million passengers per year will use Dublin Airport. By using a public private partnership to implement this and with proper forward planning, there is no doubt that such a service will add to the overall improvement in the transport system for the city. As other Senators pointed out, the example of the metro in Madrid is evidence that it is possible to provide such a service at reasonable cost and within a reasonable timeframe.
