There's disruption in store for train users in Wicklow this weekend.
Iarnród Éireann is advising customers the final phase of its major City Centre Resignalling Project begins this October Bank Holiday weekend.
The €120 million project aims to increase the number of trains which can operate during peak hours, and improve punctuality due to the modernisation of signalling.
However it will impact on a number of services including DART, Maynooth services and commuter lines.
