Luas asked to explain Christmas service disruptions that caused 'massive delays'

A large section of the green line was shut down because of a power outage, and a signal fault saw trams suspended on the red line.

The company that operates the Luas is being called on to explain a series of stoppages and delays over the last two days.

Yesterday a large section of the green line was shut down because of a power outage. There were no services at all yesterday between Balally and Brides Glen after a problem emerged near Stillorgan on Friday.
