Major disruption on rail services south of Dublin is set to continue into next week, with no trains between Dalkey and Greystones on Saturday and Sunday. The fire, which occurred in a signalling relay room, has caused significant disruption to Dart services south of Dalkey, and Dublin-Rosslare train services, since Saturday. As no Darts are operating between Dalkey and Greystones, Dublin Bus will accept rail tickets from customers to/from areas south of Dalkey. It advises customers to use Dublin Bus services from the city centre to and from Blackrock and Dun Laoghaire. A limited bus transfer will be available between Greystones Station and Bray Station for DART services.
