Some of the project engineering costs are astronomical and we should make better use of the current infrastructure. In many cases, a stretch that has already been upgraded, such as the one into Galway, should be used more intensively to provide a commuter service. I differ slightly from Senator Wilson in that I feel upgrading the Navan-Drogheda route could quickly provide a service to Navan, otherwise there would be a long wait for a new line to be put in place. The Senator also mentioned the connection to Kingscourt and, again, the line is there so why not use it? The Phoenix Park tunnel is crying out to be used. I do not understand why people want to build all sorts of other tunnels under Dublin when the existing tunnels are not used. People say that it is unacceptable that passengers would have to spend a quarter of an hour travelling to Heuston Station, via the Phoenix Park tunnel, to Connolly Station. Is that quarter of an hour worth billions of euro? We must make best use of what we have.
