Today (7 October 2016), Dublin’s LUAS Green Line was out of service owing to an unspecified disruption.
Mark Healy and I were exploring progress LUAS Cross City works near the St. Stephen’s Green, where we found no-less than four Alstom Citadis trams inoperable and parked.
As of 2:45pm, LUAS was reporting that Green Line service remained suspended.
More recent reports indicate it could be Saturday morning before service resumes.

I exposed these photos of the stalled trams using my Lumix LX7.
