The National Transport Authority have ruled out any plans to run Luas services overnight, saying it would disrupt essential maintenance works.
In June NTA CEO Anne Graham said they were "looking to see" if they could extend the tram network's hours during peak times to take some pressure off taxis.
She told RTE's Primetime: "There's a particular difficulty on our rail systems because they don't operate for about four hours which is between 1am and 5am. A lot of track maintenance and vehicle maintenance is done overnight so they need those periods of time in order to do that maintenance.
