The Transport Minister Paschal Donohoe has welcomed news that strike action at Irish Rail has been called off.
A revised set of proposals was hammered out at all-party talks, which will now go to a ballot of union members.
Minister Donohoe says all parties are aware of Irish Rail's "financial predicament", and said the agreement is "essential" to addressing its challenges.
Irish Rail spokesman Barry Kenny says the controversial pay cuts are still on the cards, but have been deferred for three weeks to allow workers to have their say in the ballot.
He has also outlined some of the other measures in the plan, saying: "The NTA will engage with the company trade unions on the future financial infrastructure of the company, there'll be a quarterly forum between the company, the trade union, the NTA and the Department of Transport.
"We've given a further commitment that there'll be no further pay reductions for the duration of the agreement; and that we will work to look at future productivity as well."
