Luas operator Transdev apologised for any inconvenience caused, confirming in an update at 4.30pm that the Green Line is still entirely down. On its website, the Luas operator said the service disruption has been caused by a power fault, the cause of which it cannot yet confirm. “Multiple Luas technicians are on site and are working systematically along the Green Line to identify the source of the fault,” it said.
