yep we were told the enterprise was delayed by 20 mins due to security alert. what arrived 20 mins later was a 4 car commuter train. the train is as packed as a normal commuter train by the time it reaches balbriggan. nearly everyone is standing from Dundalk. I suspect we will be told to switch train in drogheda to the 8.32 drogheda train! expect the dublin-belfast train to be switched at connolly
