The five days of introductory free travel period on Dublin’s new LUAS system has ended, with the trams accepting fares from this morning.
Almost half a million people have used the LUAS since the Sandyford to Stephen’s Green line opened five days ago.
Sixty thousand people are expected to travel on the line every day.
A LUAS spokesman said staff would be present at all stops on the line for some time to help people get used to the new ticket machines.
