DART users are angry at Irish Rail over timetable changes which will see fewer trains stopping at three northside stations.
From next Monday, DARTs are to run at increased frequency, meaning there'll be a train every ten minutes in both directions.
However it means Dundalk and Drogheda services will no longer stop at Portmarnock, Clongriffin and Howth Junction.
This is to free up capacity for people living north of Donabate, but angry Portmarnock commuters are calling on Irish Rail to rethink the decision.
Irish Rail says trains serving Portmarnock will now have extra capacity for people travelling into town,
However it's promised to review the situation to see if it's "catering for demand from all stations in the revised schedule"
