Airport rail links and a proposed new station at Craigavon are among the recommendations of the final report from the All-Island Strategic Rail Review.
But restoring a railway line to Enniskillen has been ruled out.
The report was published in draft form in July 2023, with a consultation afterwards.
Among its recommendations were connections to international airports and the restoration of the line from Londonderry to Portadown with a view to increasing North West connectivity.
The final version now contains 32 recommendations.
