With work due to be carried out across the rail network this bank holiday weekend, it could mean travel disruption for tens of thousands of passengers.

For anyone planning to take a train or Dart, they may have to take a bus instead with Iarnród Éireann relying heavily on the bus network to take additional passengers on several routes.

The Cork to Dublin rail line will be affected with all rail services Saturday and Sunday being operated by bus transfers between Mallow and Cork, and train services operating from only Mallow to Dublin Heuston.

It is a similar situation for the Dublin to Belfast line, with bus transfers in place instead for the weekend.

The DART will also be curtailed with no northside Dart services for Saturday and Sunday.

Dublin Bus will accept valid rail tickets for travel within the affected DART route.

Iarnród Éireann is advising customers to re-check their journey details before travelling.

There will be further disruption for rail passengers next week as the first of five rail strikes is due to take place next Wednesday.
