[06/11/2012] Delays to all Morning peak DARTS and Northern Suburban line services

[Rashers]

Nothing on the IE website, overhead displays, or certainly on the train I was on, or in Connolly station.
But there were 15-20 delays to all Bray bound services around 8-9am. The 07.40am Connolly to Belfast was also 15-20 mins late.
Examples:
E103 Malahide to Greystones Scheduled 08.38 Due 08.54
P603 Drogheda to Bray Scheduled 08.44 Due 08.57
E204 Howth to Bray Scheduled 08.54 Due 09.06
P604 Drogheda to Bray Scheduled 09.01 Due 09.13

Any ideas on what caused all the delays?
