Metrolink, the largest infrastructure project in the history of the State, is set to carry its first passengers between 2036 and 2038, and will cost a maximum of €17.5bn.
Transport Infrastructure Ireland and the National Transport Authority say that, when completed, the giant underground project will see between €1.13 and €1.95 in economic benefits returned to the taxpayer for every €1 invested, with no scenario in which the rail link will cost more than it creates.
