You know it's Christmas when the Luas is running late.

Night Luas Services are begin this weekend, with some trams running as late as 3am.

Night trams will operate in both directions, on both the Green Line and Red Line, including the Green Line extension.

 The late trams will run over the festive season, ending on New Year's Eve.

On Christmas Eve Sun Luas services will end at 8pm.

On Christmas Day, there will be no Luas services whatsoever (hey, everyone deserves that day off)

Late night shopping, here we come.
