Iarnród Éireann says all services have returned to normal after yesterday's decision by train drivers to return to work in Cork and Kerry.
The drivers' unofficial action halted rail services to and from the south of the country for eight days.
Management and unions will be meeting Tom Pomphrett again under the auspices of the Labour Relations Commission next Thursday to deal with the outstanding issues.
Eight train services between Tralee, Mallow and Cork this morning were cancelled due to requirements to move trains after the disruption.
The company said that all other services on the Cork-Dublin, Tralee-Dublin, Cork-Tralee, Cork-Cobh and Cork-Mallow would operate to schedule.
The dispute centres on a disagreement between the company and Cork-based train drivers over training.
The disruptions began when a Cork-based driver refused to work his roster last week after being asked to facilitate the instruction of new trainee drivers.
