Rail commuters were experiencing significant knock-on delays on Monday evening after all Dart and commuter rail services were earlier stopped “due to a major signal fault”. The signal fault was rectified at about 6pm but Irish Rail warned of knock-on impact. “Signal fault has been rectified, but expect knock on delays of up to 30mins to all Dart & Commuter services and Sligo, Belfast & Rosslare services,” it said in a tweet. At about 5.50pm Irish Rail said all of its Dart and commuter rail services had been stopped. This was rectified a short time later.
