Overview
- Transdev said Green Line services will operate from Brides Glen to Broombridge from 6 p.m. with 15-minute frequencies until 12:30 a.m.
- The fault was identified in a low-voltage 48-volt safety system, not the overhead traction power that drives the trams.
- Because the fail-safe circuit was detecting a fault condition, power could not be restored until engineers resolved it.
- Technicians worked overnight across substations, inspected 12 sites, and narrowed the issue to the area between Broombridge and O’Connell Street.
- The Red Line is running normally, Luas tickets are being accepted on Dublin Bus, and earlier disruption contributed to heavy traffic including delays near Dublin Port.
