Rail services between Belfast and Dublin face major disruption, with service changes expected while repairs are carried out. Multiple outlets report that the disruption is linked to damage to an overhead electrical line near Raheny. The disruption is expected to affect commuter travel during the morning period, with operators hoping issues can be resolved by lunchtime. One report estimates that between 15,000 and 20,000 commuters could be impacted, reflecting the scale of the interruption. Authorities and rail operators indicate that service disruption continues until the overhead line damage is repaired and the affected infrastructure is made safe for normal operations. As a result, passengers may experience delays, cancellations, or altered timetables while investigations and repair work take place. Further updates are expected as the situation develops and rail services move back toward normal scheduling.
