    They wrote an article filled with inaccuracies about the changes BusConnects would bring to the commute of a blind man who lived on Collins Avenue. Previously he would have had to take a 14 to Connolly and then change to the Luas to get to his workplace at Spencer Dock.

    They claimed his two part journey would become a "six-stage ordeal". Actually, under the BusConnects plan at the time (and maybe still now) he would have gone from a two part journey to a single trip on the N4 bus.

    I presumed the journalist involved, Brian Hutton, was simply too lazy to do his own checking of what he heard from the man, and simply repeated the incorrect assertion. I requested if the IT and Brian himself could at least reach out to the man to ensure his anxiety over the route changes wouldn't continue, if they weren't going to do a correction.

    Heard nothing at all.

    It's rare to come across real journalism in this country anymore, and this was an example of very bad journalism with a real victim. I'll never take anything printed in the Irish Times on faith ever again.

    I believe I recall seeing a comment from Hutton that the man in question had to travel via the city centre for unspecified but important reasons and that he stands by his story.

    So basically, they made a huge story about someone who travel from Collins Ave to city centre to docklands goes from 2 buses to 3 under the new plan. An insanely specific and unusual route that wasn't 100% catered for in a massive network redesign. That article is an utter nadir in appalling journalism.

    Yes, it's one of the orbitals, the N2 or the N4, so that's something at least.

    The N4 is the one on Collins Avenue.

    I can't wait for these orbitals. One of them will take me almost from my door to my office, a journey I currently would never dream of taking at the moment as it currently involves getting a bus into town and back out again.

    Also it opens up easy access, with no changes, to Phoenix Park, Heuston and Connolly Stations and Blanchardstown.

    They will really revolutionise access to the whole city for those without cars IMO.

    That article was terrible.

    Going from that IT article on Bombardier. In terms of aesthetics; I would think that the Innovia Metro 300 would be a perfect fit to have as a driverless train being provided for Metrolink. The passengers in Dublin & beyond that would probably consider it to be a huge hit for them if people are commuting to work from outside the GDA because it just looks so attractive to the naked eye.

    I mean just look at it from the point of aesthetics. It is fresh, it is modern & it is a very sleek looking piece of infrastructure. Does anyone else love the look of it?

    One question I have about these orbitals:
    Will there be continuous bus lanes/ bus priority on these routes and if so how long before this infrastructure is in place to service the new orbitals.
    Thanks.

    Apologies only seen the mid note after I posted.

    Not much about Metrolink in the budget, other than this:

    https://twitter.com/rtenews/status/1316009771590279170

    On the other hand — not much about Metrolink in the budget is probably good news all things considered.


  • Registered Users, Registered Users 2 Posts: 9,761 ✭✭✭cgcsb


    The additional billion is an increase though. It'll probably be used on bringing smaller projects to completion faster. More money won't really help metrolink at this stage. It'll be 2022 at the earliest for any building work to start, perhaps 2023 more likely, if at all.

    The 2021 Expenditure Report states that Metrolink will be submitted to ABP in 2021. No funding required for this so that's why it wasn't included in the Budget today.

    BusConnects Corridors and DART+ West are to go to ABP next year also. Big year for PT.

    I see Nurnberg opened a metro extension.

    1.1km plus a station for 69m, seems good value.

    Does anybody know was it bored tunnel or cut-and-cover?

    Our costs seem higher?


  • Registered Users, Registered Users 2 Posts: 17,854 ✭✭✭✭Idbatterim


    seeing as multiple magic money trees have now been found, lets hope they can find the pittance to actually develop this project OR come 2021, 2022 will they be saying, oh there actually is no ability or justification to borrow this pittance for this vital project, time will tell!

    We now have the greens in government, maybe they can make amends for the idiotic policy they supported of near free motor tax from 2008 , for the most unsustainable mode of transport, even moderate motor tax and they could have had billions extra to develop rail, cycle etc infrastructure :o

    Extending an existing service would cost a lot less than building a whole new system. We need to set up all new computer systems plus it being driverless, new control centre, new depot, full new fleet of rolling stock, etc.

    Our Greens aren't real Greens.

    I take that personally, the greens aren't a monolithic entity, I certainly think there is a proportion of them that mean well but are so divorced from either reality or the lives of the working class that they come up with awful plans, The science at the time said CO2 bad, and Diesel particulates = Less bad, Electric cars were nowhere near as mature as today, and yes it wasn't a very well thought out policy, (I wasn't in the greens back then).

    The greens of 10 years ago are different to today, and I expect will become considerably different in the coming years, they have seen a nearly tenfold increase in their membership since the last time they were in government, most in the last 3 years, so I would expect a bit of a change over the next few years.

    I think we would have seen a lot of change this year if some of the more left members had waited until after the leadership election and convention to leave the party, a good few things didn't pass by a bare few votes...

    Sorry for the tangent, I would say one common criticism of the Irish greens is they are actually overly focused on infrastructure over other environmental aspects, so I would count this government as a true failure of the greens if it didn't at least deliver on that one key aspect in cycling and rail.

    Given that the minister responsible for Metrolink is not just a Green party minister, but is the leader of the Party, I would expect him to come out strongly advocating for it, and putting it in a direction that it should be fast-tracked so its completion is not delayed.

    Metrolink will allow for significant modal shift towards PT, and that should be shouted from the house tops. He should also be pushing for P&R facilities everywhere they could work.

    He should also look for plans to solve the St Rephaella's Road crossing as a stand alone project to remove at least one of the problems stopping the Sandyford extension.

    It is time to push for this to get the tunnel boring machines into the ground.

    So what has become of the 'micro consultations' on highly technical matters like siting intervention shafts. I really hope this goes ahead, would love to see building work in 2022. I can't recall the state having spent this much money on one item before although relatively speaking I bet Ard na Croise cost more.

    At the risk of straying off topic, Ardnacrusha cost £5 million or 20% of the states GDP at the time.

    Minister Ryan spoke at a Transport Ireland conference the other day and was adamant this will proceed following a question on same.

    Worst case scenario, timeline might change by a year or two. That's my own verdict by the way. Lots happening such as review of NDP, review of GDA Strategy next year.

    If there is work on site in 2022 it may be possible to complete and open by 2028 but I think it's more likely 2029/30, assuming the project goes ahead.

    I'm afraid you give me too much credit;). The plan for the metro to go through Drumcondra came, of course, from the RPA.

    It was the idea of the RPA's successors to move it away from there and to an area (i) with a lower population and much lower population density in its immediate catchment, and (ii) which is very close to the LUAS green line and will have a station serving the M3, Maynooth and Hazelhatch lines.

    A feasibility study will also be carried out on extending the Metrolink to Rathfarnham/Knocklyon or to UCD.


  • Registered Users Posts: 270 ✭✭ncounties


    Based on this timeline, would that mean the earliest we could see construction would be 2023?

    A feasibility study will also be carried out on extending the Metrolink to Rathfarnham/Knocklyon or to UCD.

    Is that an extension or a separate line? A UCD route would be technically difficult considering the end point of the tunnel under Ranalagh

    The UCD and Malahide Road corridors have sufficient space to accommodate surface luas lines that could have a North-South connection somewhere in the Docklands. The luas needs more capacity in the Central area so a new North-South crossing would be very useful especially in the growing docklands. A Tallaght to Beaumont metro line should also be considered but I just think that's getting way ahead of ourselves. At present we don't have integrated ticketing or bus lane enforcement, the bread and butter of a public transport network.


  • Moderators, Computer Games Moderators, Recreation & Hobbies Moderators Posts: 10,399 Mod ✭✭✭✭CatInABox


    Judging from all the talk about it previously, this is a replacement for Metro South, so an extension of the Metrolink line. Despite all the talk about it, no one has answered the question of what happens to the Green Line in this case. Despite all the improvements currently being done, and planned, the Green line will be way overcapacity again once all the developments on the line come on stream, and without the ability to upgrade it and connect it to the Metrolink.

    I still think the Metro South upgrade is still the most likely project. Any Cost Benefit Analysis and comparison of the various mooted projects will have the upgrade way, way out in front.

  • Registered Users Posts: 10,666 ✭✭✭✭MJohnston


    From previous crayoning by the Greens, they wanted a Metro spur from Charlemont or Ranelagh to UCD and then onwards to Sandyford. That would alleviate some of the pressure on the Green Line.

    I was firmly against that proposal when they were talking about doing it instead of the Green Line upgrade, originally, but given that that upgrade seems like a non-starter, I’d be supportive of a UCD extension.

    But only when it’s proposed as an extension. Get the Ranelagh to Swords Metro permitted, get the tunnelling commenced. While you’re doing that, plan the UCD spur separately, and if it all works out, the tunnelling could potentially be able to continue from the Swords segment without interruption.

    Eamon Ryan is too gormless to think that clearly about it though, so god knows how they’ll mess it up.

    Another thought - the UCD spur should 100% use the Eastern Bypass reservation and it should link up with the DART at Booterstown.

    You do realise that the mention of reviewing Metro lines here is in the context of the NTA implementing the review of the Dublin Area Transport Strategy, which they are legally obliged to do.

    https://www.nationaltransport.ie/nta-publishes-issues-paper-ahead-of-revising-greater-dublin-area-transport-strategy/

    Certainly I think that the recent consultations on Metro and BusConnects will have raised the profile amongst the general public of the strategy and the need to actually make a submission.

    I think it largely went over peoples' heads the last time around, until they began to understand the implications of it when the detailed proposals got published.

    I am sure that a separate thread will be started on the subject in due course.

    I do think your comment about "integrated ticketing" which you seem to keep repeating, needs a reply here. You are implying that nothing has been happening about it, which isn't the case at all.

    Firstly I'd point out that for regular commuters, there have been integrated multi-mode period passes for years, with monthly and annual tickets on offer.

    But, the 90 minute ticket is presumably what you are referring to, which will allow an individual journey to be made across all modes provided the final journey starts within is an integral part of BusConnects, and it is coming.

    There has been a steady restructuring of all the fares charged every year in annual NTA fare determination reports, and indeed of the monthly and annual ticket pricing. This was done over a period of years to avoid an unnecessary shock to the operating company finances and to consumer pockets, with a view to arriving at two fares - one a short journey fare and a second 90 minute fare. It would not have been affordable otherwise.

    I would fully expect the 90 minute ticket to be introduced when the BusConnects network changes start being implemented in 2021 given that the redesigned network will be encouraging many new trips using more than one single journey.

    Perhaps it may not happen with phase 1 as that would appear to be just a restructuring of the Howth Road routes, but I'd certainly expect it with the next phases as the new orbital and local bus routes start being rolled out. The plan won't work without it.

    Edit - Apologies Sam - was writing this and got interrupted before you'd posted your Mod Comment

    National Children’s Hospital Mark II! I don’t think it should finish in Ranelagh or more properly Charlemont. Problem is, suggesting that design changes might be made as the project progresses is just an invitation to be screwed by the contractor.

    The current Metrolink project will stay as is, any extension would be an entirely separate project. The focus should be on getting the existing Green Line upgraded to Metro as originally planned. The demand is already there and it is relatively cheap to do so, there wouldn't be another project that gives as much bang for your buck.

    This feasibility is just Ryan indulging his fantasies but the chances of something actually happening from it are very low. It is really just another report to go on the shelf. Ryans waffling about the WRC tells you all you need to know. Hopefully the next Minister will be more pragmatic.

    Whatever they decide to do won’t affect the current Swords-Charlemont route.

    That debate is about the strategy up to 2042 and what to do next, and at last I’d like to think that a proper discussion about how to develop public transport in south Dublin over that period could now take place. The public didn’t engage to any significant degree when the previous strategy was originally published.

    The debate that has happened since as a result of the Metrolink and BusConnects consultations certainly has awakened the public interest and that is not a bad thing.

    The discussion is about starting construction while contemporaneously considering a change to the design, ie it continuing further under ground. I think it should but that should have been sorted over past 18 months. Without a final design which can be pursued, it is a contractor’s opportunity to extract whatever they want, like BAM at NCH.

    I think that passive provision will have to be made in the ABP application for continuing beyond Charlemont.

    It will continue in some form or another.

    It cannot surface at Charlemont due to the sewer.

    It’s not about planning. It’s about signing a deal with a contractor to dig a tunnel which ends in ranelagh (beyond Charlemont for turn back) probably dumping the tunnel boring machine there. If they decide, during the construction phase, that they want to extend beyond there and surface elsewhere, it will require changes to that contract which can’t be forced and for which the NTA will have no bargaining power. Hence why I say it would be expensive. For example, the contractor may seek to recover any irrecoverable overages on the ore existing contract or simply hold out for his ransom payment.

    The chances of changing the contract after signing to extend metro is practically zero. There are many many years of design and planning in any extension before we get to that point. That really isn't a concern.

    How would you plan to “extend” an underground line which terminates in a congested area? You could start from the other end but none of those which have been proposed are easy kick off points either. It’s poor project organisation for something which has been mooted for 20 years or more. One of the reasons why we have disproportionately high costs and, consequently, inadequate infrastructure.

    Whatever you want to do, you still need need to go through feasibility, various stages of design, plenty of consultations and ultimately get planning permission before anything can happen. Given how long that has taken for the progressing metro scheme, any new scheme is unlikely to be possible to add onto Metrolink. There would also be lots of question marks over adding multi billions in extra works onto another contract. In reality, any extension will have to be a separate project after Metrolink is built.

    I don’t know the practicalities of it but I hope the ends are done in a way that allows for future extension, whether that means an extra 100 meters of tunnel or having the last bit slightly curved or whatever. Beyond that sort of thing in the initial design nothing from the priced job should really be changed unless completely necessary.

    That's the kind of planning I was hoping for, given the circumstances. It was pointed out that any further tunneling (in same direction) would require a new shaft opening for earth removal or delaying the operation of Swords to Charlemont in order to use existing opes.

    Phase 2 tunneling from south to north is possible but then you're back to square one regarding from where to start!

    Most elegant solution is link to green line and upgrade to Metro.
