That sounds like chaos. Especially when its finished, Exit validation at balbriggan will cause murder. There is usually in excess of 200 people getting off each commuter that arrives at rush hour, try and fit that through machines in a hurry!
Also, even when or if the station becomes the illogical terminus of the dart, how will they handle DMU's and the enterprise rolling through as well as added EMU's? The station has 2 tracks, its not like bray with a siding right behind it. The Drogheda line will still have to be busy, adding Dart's will only complicate it, unless there is 4 track sections put in, or even a 3rd exclusivly for the Enterprise and other express service's.
