Mr Carbone said he was hoping ground would be broken on Luas Cork before the 100th anniversary of the last trams running in Cork on September 30, 1931.

“Public consultation on the preferred route will run until June 12,” Mr Carbone told the launch event.

“After that, we will consider the feedback and refine the revised route.

“It is envisaged that we will submit a railway order, which is our planning, in early 2028.”

Allowing a year for An Coimisiún Pleanála to grant planning permission, Mr Carbone said the project would then go to tender.

Construction should begin by 2031, he added.

“Typically, a project of this scale takes five years to build,” Mr Carbone said.

“So, I hope to welcome you all in 2036 on the first tram.”

When the emerging preferred route for Luas Cork was published last year, unofficial estimates put its likely cost at “€1bn-plus”.

However, construction inflation has since affected those figures.

“Currently, we are budgeting in the region of €90m-€120m per kilometre for light rail,” Mr Carbone said.

With the preferred route now running at just over 20km, that would mean Luas Cork might currently cost between €1.8bn and €2.5bn.

It is the first time anything approaching a definitive timeline has been offered for what Taoiseach Micheál Martin has predicted will be a “transformational project” for Cork.

However, one observer at the preferred route launch at 1 Lapps Quay on Friday suggested that the phrase “subject to funding and permission” was doing a lot of heavy lifting at a time of growing economic uncertainty in the region.

Separately, TII chief executive Lorcan O’Connor said Luas Cork will not be a 24-hour service, but rather will probably run from 6am to 1am each day.

“It’s unlikely to be a 24-hour service, as you need to be able to service the track, and that would be common to all rail services around the world,” he said.

With the latest round of non-statutory public consultation running until Friday, June 12, Mr Carbone said he had one ask of the people of Cork: “Engage, engage, engage.”
