Unions and management at Irish Rail will meet tomorrow in a bid to resolve unofficial industrial action.
The dispute began when the company introduced its new roster for trains operating between Cork and Cobh last December.
Some train services on the Cork to Cobh line were cancelled today, with passengers being transferred by bus instead.
Some drivers at Cork station are refusing to operate the new schedule and are continuing to operate the old one.
Trains cancelled today were the 7.30am, 9.30am, and 11.30am service from Cobh to Cork, and the 10.30am and 2pm service from Cork to Dublin.
A bus transfer has been in operation since the dispute arose in December and tomorrow's talks are aimed at bringing an end to the current impasse.
