This service follows the Cork route as far as Limerick Junction. Limerick services leave the main line via a direct curve built in 1967, onto part of the former Waterford and Limerick Railway (W&LR). The former two hourly timetable operated by 22000 Class railcars was cut back in November 2009 when the number of direct trains was reduced to three from Dublin to Limerick and four from Limerick to Dublin. On Sunday there are 6 trains in each direction. The remaining Dublin-Limerick-Ennis services involve a change at 'Limerick Junction' from a Dublin-Cork or Dublin-Tralee service onto a local train for the remaining 30 minutes of the journey.
