Services on Dublin’s Luas Green Line remain suspended this morning while repair works continue following a power failure.
The fault yesterday morning resulted in a loss of power to the Green Line and a temporary loss of power to a section of the Red Line, which has since been fully restored.
Luas operator Transdev said there are no services on the Luas Green Line from Broombridge to Brides Glen, with services not expected back in operation until after rush hour.
Engineers have identified that the fault lies within a critical low-voltage safety system known as the 48-volt system and not the overhead power system that powers the trams, it said.
Transdev Director of Communications Dervla Brophy said it is not yet possible to say when service will be restored.
Speaking on RTÉ’s Morning Ireland, she said technicians were on site overnight and have inspected 12 sub-stations.
Ms Brophy said the issue has been identified as a fault with a safety circuit that controls the power from the sub-stations to the control room.
“We have narrowed it down from the area from Broombridge to O’Connell Street. We are working our way systematically through the Green Line and substations in order to restore power,” she said.
Ms Brophy apologised to commuters said Luas will continue to provide updates on the Luas app, website and social media channels.
Engineers are working to restore power
Transdev said in a statement this morning that the system is designed to shut down power to the overhead lines in the event of an emergency. The system is currently detecting a fault condition and, for safety reasons, will not permit the power to be fully restored until that condition is resolved.”
It said Luas tickets are being accepted on Dublin Bus services.
