Irish Railroad said services were suspended between Clontarf Road & Howth Junction after a serious Harston accident.
All DART and Commuter services are suspended, Dublin Bus accepts rail tickets and bus transfers for corporate services are organized.
Emergency services are currently in place, and the Irish Railway Company said that "continued destruction" is likely.
More to follow.
Since then, services have resumed following a "tragic incident" on Harmonstadt.
