RTÉ is reporting that Fianna Fáil's Transport spokesman said he would have been quicker walking than taking the Luas Cross City Line.
The Dáil was told that Robert Troy took the Cross City line from Dawson Street to O'Connell Street on 15th February, so that he could experience for himself, the length of time that it takes.
Troy said in the Dáil that: "It took 20 minutes, I would have been quicker walking.
"Coming back I took a taxi in order to be here for Question Time [it took] 25 minutes.
"People are actually spending longer on public transport now than before this was introduced."
Minister for Transport Shane Ross said in response that he expects the long waiting period to be fixed "very quickly" but for the time being, it seems like there is no short-term solution to the problem.
Ross called the situation a "teething problem" because of lack of capacity.
