Further disruption is expected today for rail travellers heading north after a freight train derailed on Thursday night.
All northern line commuter trains are suspended and people travelling from Dublin to Belfast and back will travel to Drogheda by bus and from there by rail to Belfast.
Southbound Belfast/Dublin services will operate by rail from Belfast to Drogheda and by bus transfer from Drogheda and Connolly Station, Dublin. A delay of 30 to 40 minutes delay may occur on these services.
Up to 7,000 commuters suffered severe delays on the journey into the capital yesterday after the freight car derailed between Skerries and Lusk at about 11pm the previous night.
Iarnród Éireann, which yesterday temporarily reopened the line to deal with the evening and weekend rush, said the track would now be closed until at least Monday.
Further details are available from the Iarnród Éireann website.
