There is chaos across both Luas lines this evening. Green and Red line services are running with "significant delays" due to a system fault.
Luas says it has "technicians on site working to resolve this fault", and has apologised to passengers for the inconvenience.
A technical issue means the Luas live feed to the app, website and platform Passenger Information Displays is down, and it is also affecting the company's ability to make live announcements to the stops.
Escalators and lift at Connolly are currently out of order, and clamping is suspended at all Luas Park and Rides.
Luas tickets are valid on Dublin Bus services for both the Red and Greens Line as an alternative to LUAS services due to delays.
