The long-delayed Dublin Metrolink is to cost €9.5 billion, and the first trains are set to run by 2034. So the cabinet was told yesterday.

The 19 kilometre rail line is set to run from near Ranelagh on the southside of the city to Swords on the northside, serving Dublin Airport along the way.

Joining Shane for more on this was Brian Caulfield, Associate Professor School of Engineering at Trinity College Dublin.
