The National Transport Authority is examining how the Luas can run between the hours of 1am and 5am on Friday and Saturday nights in a bid to ease pressure on the taxi industry.
TDs have said the lack of taxis in Dublin city centre is becoming a "serious issue" and have called for "swift action". Figures released to Dublin Rathdown TD Neale Richmond show that just 32 taxis and licensed vehicles have been added to the Dublin's ranks so far this year.
He said: “Not only do we have a lack of taxis, but drivers are choosing not to work when we need them the most. Only 29% of taxi drivers are currently working during the evenings, weekends or on bank holidays."
