    Grand Canal Dock station, between island platform (1,2) and the ticket barrier shed off Platform 3. It's in addition to the existing footbridge but the planning notice says it's only for evacuation use.

    that doesn't make any sense - why would you build a bridge and only use it for emergencies?

    because you may have been told to or shut the station?

    That doesn't really answer the question. If the bridge had to be built for evacuation purposes, why not *also* use it for day to day purposes too?

    The Met has separate tracks to facilitate fast and slow services.

    The DART line is just two tracks, one for each direction. So there is no point in running "fast" services as they will still be stuck behind the train in front of them. Also, your idea would mean people travelling between stations then skipped would have a nightmare trip. Not everyone is going to/from the city centre.

    Given the infrastructure in place, a consistent 10 minute DART service serving all stations is the best solution for everyone along the DART line, interspersed with diesels from the Northern, Maynooth, Kildare and Rosslare lines.

    To explain this - if you have two DARTs within 10 minutes of one another, and a Northern line train and Maynooth line service both sandwiched between them across the loop line in the city centre, one of those diesels is going to have to follow the DART to Bray - there won't be room for the both of them at GCD.

    You have to think about how much capacity the infrastructure has.

    The 29k or ICRs sets are no slower than the DART, particularly given they would skip stations so they are not holding anything up. I also think you'll find their emissions are well above required standards, so again I think you really are going OTT.
    I appreciate the Met has four tracks, but is much longer than the Dart system.

    If we take the situation a Piearse, a dart arrives at 16:58 and next stop is Blackrock. Next Dart arrives at 17:01 - all stations. Passengers on the Dart for stations before Blackrock then get off and wait for the next one, as do those on the platform travelling to stations before Blackrock. This first train will then be 10 mins ahead of the second train from Blackrock on, with a better balance of passenger numbers. This station skipping already happens with 29k trains.

    Acceleration of 29ks is much slower than Darts, and the noise is much greater, both at the station and travelling up to speed. They are also very smelly.

    How does the 10 minute frequency affect the level crossings between GCD and Booterstown? The gates could be closed at some points for most of the time.

    I'm only going to say this one more time.

    The NTA have decided that they want a standard all stops 10 minute frequency from every DART station between Howth Junction and Bray. That's their decision.

    So going on and on about DARTs skipping stations is pointless. It's not going to happen.

    As for the 29k sets - well if you dislike them that much, don't use them. No one is forcing you to.

    But that doesn't mean that everyone on the lines served by them should be forced to change trains just because you don't like them.

    having capacity at Pearse to store the 29ks would solve some of the above and remove the need to run to Bray, no? Pity all the functionality was ripped out.

    Don't forget, there is still sidings south of Pearse, and a third platform at Dun Laoghaire to turn diesel trains. GCD will be the best spot to terminate trains due to the lack of conflicts, but there are other options.

    I wonder if the Maynooth services that currently turn back at Connolly platform 7 will continue to do so, or go onwards to the new GCD terminus. Probably the former, since the the platform 7 turnback avoids the bottleneck through Connolly which will be even more congested with Kildare line trains and more DARTs coming through, albeit with the improved signalling.

    Most of those trains that terminate at Connolly turn around quickly to go back out so I'd be surprised if that changed.

    Going around to GCD would take far more time.

    Third rail is back at GCD, and track / signalling work seems to be progressing nicely. They have new signal lights put up and covered over for the moment.

    Have they started on the overhead electric wires yet?

    Doesn't look like it. None over platform 1 yet anyway.

    they haven't finished the track yet, so could be a while.

    No rush then. I suppose they have to wait till they get round to fishing the signalling project as well.

    Mind you, no rush fits Irish Rail so well.

    Launch date for the project is Spring 2016 so some time before then.

    Northbound trains are now using platform 1. Platform 2 is buffered off at the south end. New footbridge is now open, in addition to the existing one!

    Big purple train station! I'm guessing you work in Google?
