Luas Red Line services are operating normally.
Green line Luas services were suspended yesterday evening during the rush hour commute causing traffic chaos in Dublin city centre.
Luas tickets are being accepted on Dublin Bus while the service is out.
A statement said: “Luas Engineers have identified that the fault lies within a critical low-voltage safety system known as the 48-volt system.
“This is not the overhead power system that powers the trams. Rather, it is part of the safety network that links substations to the central control room and allows power to be safely controlled and monitored across the line.
“In simple terms, this safety 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.
“As a result, services on the Green Line remain suspended while repair work continues.
“Multiple Luas technicians are working to identify the source of the fault and restore power.
“We apologise for any inconvenience caused.”
Dervla Brophy, the director of communications with Transdev, told RTÉ Radio 1’s Morning Ireland that “everything is being done to resolve the issue”, but it “will take time”.
“We don’t, at this moment, have an idea as to when we’ll be able to restore power to the Green Line,” she said.
“But we do want to reassure customers that we are working our way systematically through the Green Line and the substations.
“We have identified the issues, and we apologise to Luas customers and the public for this service disruption.
“Our tickets are valid on Dublin Bus, and we are doing our best to restore the service as soon as we possibly can,” she added.
The company said Red line services are operating as normal, and that Luas tickets for the Green line are being accepted on Dublin Bus services.
