Strike action has been called off at Irish Rail after both sides in the dispute agreed on new set of proposals at the Labour Relations Commission.
Both SIPTU and the National Bus and Rail Union say the agreed document is comprehensive and addresses all of their concerns.
Irish Rail has said the proposals will help protect the future viability of the company.
The proposals will have to be put to a ballot of union members.
Representatives from SIPTU, the National Bus and Rail Union and Irish Rail management emerged from the marathon talks at 1.30am.
General Secretary of the National Bus and Rail Union Dermot O’Leary said the proposals address issues including trust and confidence in the company, its financial infrastructure and its future sustainability.
Owen Reidy from SIPTU said the introduction of temporary paycuts at Irish Rail have been postponed, pending the outcome of the ballot.
Spokesperson for Irish Rail Barry Kenny said he believed the proposals would help to protect the financial viability of the company and protect the interests of customers and staff.
He welcomed the lifting of industrial action.
Ten of thousands of people were set to face disruption on Sunday, Monday and 20 September.
Irish Rail say full services will now operate on those dates.
