I also heard arguments this evening about the linking up of all the systems, which is desirable. Given time this will occur. Surely it is of some benefit that even the Luas line from Tallaght to Connolly station links in with Heuston station and Bus Áras because 15 million people pass through these stations each year. Instead of building all the systems Harry Potter style, it is not such a bad idea to be able to convenience 15 million people with the current Tallaght to Connolly station line.
