    While it's fine to complain it's too late now. Any tweak and the project would have to go through planning again from the start. It would be dead in reality and we can pack it in.

    Please read the mod warning at the bottom of the/your very first post in this thread.

    This has been litigated over and over and over again, by yourself in this account and by your old account.

    1. Glasnevin will be largest Irish Railway station after Pearse, Connolly and Heuston in Dublin, and likely will exceed at least two of those in passenger numbers because it is a station which finally straddles both GSWR and the Sligo railway, and the M3 parkway services. This means basically all intercity railways are at the very most, one IC service and 1 Dart from being connected to Metrolink, and in many cases will be more seamless than that. Drumcondra is a small station with much lesser relevance, and will likely become less relevant as a station once Glasnevin is built because of its relative catchment. Its utility as a transfer station is basically nil.
    2. If you read the route options report, you will see that in order for Metrolink to serve Drumcondra it would likely require a bored out station under the Mater as the new hospital expansion which has been built is over where the cut and cover site would have been (and please don't mention the reinforcement wall, it would still require a mined out station for significant cost with questionable benefit)
    3. And again, if you read the route options report, Glasnevin station will provide a much greater unique catchment area vs. Drumcondra as its catchment is already significantly overlapped by the Mater and Griffith Park.
    4. And finally, it is much much much less costly to build a future proofed station at Glasnevin which can actually facilitate significant numbers of people transferring from Irish Rail, to Metro for onwards travel to the Airport. There really isn't any potential future for expansion at Drumcondra which wouldn't require knocking down a significant amount of houses, and even at that stage, the GSWR and Sligo railway lines are quite far apart at this stage.

    They aren't going to redesign the tunnel. Your crayons are wasting everyone's time - just like they always have, over all the years you've done it

    I think you forgot Tara Street, which, to my understanding is the busiest rail station in the country

    just spotted this, which piqued my curiosity as it did not seem right.

    in 2019, it was fourth busiest; approx half the number of passengers in connolly. The order is connolly - pearse - heuston - tara street.

    in 2023, the order had not changed but the actual figures are not in the report.

    A last ditch effort to push this nonsense, given a planning decision is, apparently, imminent.

    Mod: I have deleted a bunch of posts discussing a posters previous existence, that posters obsession with Dumcondra, and variations on the existing plan for Metrolink which is waiting an immanent RO.

    I should have deleted more, but I have better things to do, given it is a BH weekend.

    Please do not feed a troll.



  • Registered Users, Registered Users 2 Posts: 1,365 ✭✭✭Busman Paddy Lasty


    So eh how about a proper orbital line. Has one been proposed in the thread so far?

    Seoul Line 2 is a loop that has enabled new lines over the years to intersect and have high quality transfer stations.

    Dublin MetroLink 2 could be a large circle. Luas and Bus spines could act as transfer options as we may never get the density required in semi d suburban areas.



  • Registered Users, Registered Users 2 Posts: 1,450 ✭✭✭Consonata


    Judging by the future plans that the NTA have published, saying that Metro West is on their road map (albeit going to be more luas like in nature) I honestly wouldn't be surprised if we get a MetroWest before we get a theoretical Beaumont → Rathmines/Rathfarnham underground line. There are so many things going against that project, namely cost, and I can think of half a dozen projects which would likely be more impactful per € spent (such as DU, Green Line upgrade to Metro, 2 or 3 Luas lines)

  • Registered Users, Registered Users 2 Posts: 30 Skyte


    With ML ending at Charlemont is their provision for it to, after everyone sees sense that these metro things are actually pretty decent, continue along the green line replacing the Luas?

    I'm just asking if it's been catered for in the plans not if it would happen.



  • Registered Users, Registered Users 2 Posts: 2,762 ✭✭✭KrisW1001


    This was part of the first MetroLink proposal, and it was examined in the early phases of the project, but rejected for a few reasons (disruption during construction, bad value for money compared to capacity increase interventions for Luas, would result in zero increase in mass-transit catchment, would kill ridership of Green Line south of Liffey).

    It’s not a completely dead idea, but doing it would create very long periods where there would be no adequate transport along the corridor. For that reason, I personally feel that before any extension is started, there will have to be a new “green line replacement” Luas alignment operating from Charlemont to Sandyford, possibly running near to, or on, the Stillorgan Road to serve UCD.



  • Registered Users, Registered Users 2 Posts: 1,450 ✭✭✭Consonata


    I do feel that this is a bit of a red herring.

    a) Most folk who would be affected by a 1-2 year closure of the Green line, would not be helped all that much if there was a new line on the N11. If they were then why would we be building it in the first place? If you live in Cowper you're not going to walk to Donnybrook to catch a Luas. Being realistic a rail replacement bus will be needed to facilitate the upgrade.

    b) In any other country with rail, rail replacement buses are a normal part of life, and would be perfectly sufficient to serve this catchment for a short period. Heck, simply increase the capacity of the orbital routes to the N11 which has busess supposedly arriving every 3 minutes destined for town.

    c) It also would not result in "zero increase in masss transit catchment" beyond a fairly blithe concept of "living beside a railway line". There are plenty of people who live beside the Dart or Luas currently where those modes of transport provide 0 benefit to getting them to work each day. If I live beside the Square in Tallaght, and work in Blanchardstown, why would I use the Luas. Converting the Green Line to Metro Grade increases Mass Transit Catchment in the same way Busconnects does and in the same way Dart+ does, even if in each case folk live quite close to these modes already.

    d) The Green Line upgrade remains the cheapests per 1000pphpd infrastructure investment we can make in the country, by a very significant margin. It was costed at 300-400 million back in 2017, but even if we quadruple that costing, 2bn to double the capacity of the Green Line (and double the length of Metrolink) should be a no brainer.



  • Registered Users, Registered Users 2 Posts: 2,762 ✭✭✭KrisW1001


    On point c, it really is a zero. Catchment is purely a measure of the number of people whose origin or desired destinations are within an X minute walk of the service. It has nothing to do with the service’s frequency or capacity. On that measure, replacing Green Line with a metro makes mass transport available to zero extra people in Dublin.

    The only argument for conversion is to provide a capacity increase. So, the question is, do we need that capacity now, and what (monetary and non-monetary) costs will we have to pay to get it?

    The answer to the first question is “not until at least 2040” (graph from Luas Green Line - Peak hour capacity requirements south of Charlemont ):

    image.png

    The cost for the upgrade is probably €1bn, as there’s greater segregation needed for an automated railway, but that’s still good value, but on top of that is a large non-monetary cost from disruption to Green Line. Whatever way you do the upgrade, you will sever Green Line for three years, and completely close it between Sandyford and Charlemont for 18 months. There’s no way a bus service could deal with this loss adequately: current trams carry 400 people each, while a double-decker bus can take 120. There are 20 trams an hour in each direction in peak times.

    My feeling on this is that without a new routing of Green to take away the worst of that pain, any closure to perform an upgrade will be so enormously disruptive that it will fail a CBA. On the positive side, that new routing could be something as short as a new Charlemont-Beechwood stretch (which has to be done anyway), which would immediately reduce the period where there’s a broken service on green to the 18 months when the whole line is shut down. From Beechwood, the line should strike out for UCD, before swinging back to meet its southern end at Sandyford. (Or bring Red down N11 from Ringsend to meet the tail of Green, and let “new Green” strike out west from Beechwood - there are lots of options)

    When this upgrade is to be done, what I hope would happen is that first the plan for rerouting Green between Charlemont and Beechwood is put in place, and that work is done before the current MetroLink is even open, then the RO for conversion can be put in - this is mostly non-contentious, as it’s just a service change on an existing railway, plus a tunnel portal; and as well as that a plan for the “new Green Line”, which would be constructed ahead of or in parallel with the Metro upgrade, to minimise the loss of amenity during the upgrade.



  • Registered Users, Registered Users 2 Posts: 1,450 ✭✭✭Consonata


    If I live beside a train station which gets 1 service a day to one destination requiring several transfers, I have access to mass transit, despite it being entirely useless to me.

    This is meaningfully different to living beside a station which provides a multiplier of services a day to more destinations.

    Increasing capacity, increases modal shift, increasing mass transit catchment by extension. I explained it fairly clearly already in my initial post?

    On the closure point, that we will be halving the capacity of the corridor for 18 months is simply the cost of upgrading infrastructure. London, New York, Paris does this all the time and people living in this area have a multitude of other bus options available to them. They are slower, but its not like they are living in the sticks.



  • Registered Users, Registered Users 2 Posts: 2,762 ✭✭✭KrisW1001


    Catchment is a propery of the line, not the service on it. If you live near any of the southern green line stations, the access you have to destinations along the line does not change whether that line is Luas or metro. Metro upgrade does not increase catchment, but that's okay if all we need is more capacity because it does increase capacity.

    And closure is not a case of "halving" the capacity, it's removing it entirely. That should not be done without a proper plan to mitigate the knock on effects. Three years of replacement buses is not a plan,it's an excuse for not planning.

    I'm actually in favour of this upgrade, but it's not without pain, and it's not needed in the immediate term. We can argue about how these problems can be mitigated, but pretending they don't exist is pointless.



  • Registered Users, Registered Users 2 Posts: 422 ✭✭McAlban


    I took a long long time off from posting here until something made me log in. Brightlights66 They are NOT goign to change metrolink to Drumcondra, never going to happen, the station is actually in bits, and even after Dart+ West will not be frequently used.

    You can go through Census Small Areas populations all you want but your methodology is flawed. e.g. Rush and Lusk Station area population is something like 500 People, but that excludes both towns and their hinterlands and THOUSANDS of people get the train in/out of that station per day. Where lots of people use it as a park and ride.

    Put the Crayons away and stop crying over Drumcondra



  • Registered Users, Registered Users 2, Paid Member Posts: 1,317 ✭✭✭riddlinrussell


    "Whatever way you do the upgrade, you will sever Green Line for three years, and completely close it between Sandyford and Charlemont for 18 months. "

    I think I'll have to disagree with this statement. It holds true only for the metrolink proposals to do the upgrade, which I presume will have looked to do the southern section at the absolute bare minimum cost to keep the price tag down for the whole route. Decoupled from Metrolink itself, the extension could look at more expensive options that may drastically reduce the closure times for the line.

    Some things are going to be unavoidable (Station Upgrades severing service etc) but if the tie in can be done with minimal disruption you could maybe do that as a rolling upgrade.

    People are going to be a lot more willing to put up with a few months of their Station being out of commission/maybe a movable temporary station just outside the building site (where that can work) if they know that the day the Station reopens they will have metro running to it.

    Boards is in danger of closing very soon, if it's yer thing, go here (use your boards.ie email!)

  • Registered Users, Registered Users 2 Posts: 438 ✭✭PlatformNine


    My memory for why the closure was so long on the construction report was that it was done for a tie-in option that the tie-in option selection report scored poorly. Mainly it chose the Beechwood tie-in, which its portal required digging up part of the green line south of Beechwood and required a new Beechwood station on the greenline.

    Honestly it was just a poor decision, I think if/when they look at tie-in options again, they will pick an off-line tie-in as it's really the only way to not close the GL for a very long time. I think this will be very important because as Kris says a bus replacement service really isn't going to work well in the long term. It is just too many people to try and move by bus, and a N11 replacement line, while it will help those living further south, it won't help many of the busiest parts of the Green Line. I think a very large consideration was that it reduced the CPO needed and meant they didn't have to close Dunville Ave, but I think that took too much of a consideration and the 3 year closure was more or less ignored.

    I am not sure if the original Ranelagh off-line tie in is still feasible (looking at plans I believe ML has changed quite a bit since that study), but for a comparison it was only supposed to require a few months of closure. This was becuase it essentially built the portal, ramp, everything except the final rail and bridge connection to the side, and even then I think part of the closure was needed anyways for OHLE and platform upgrades. But even if that specific option isn't possible, I think it shows the importance of why they need to consider an off-line option to try and reduce disruption.



  • Moderators, Motoring & Transport Moderators, Technology & Internet Moderators Posts: 23,559 Mod ✭✭✭✭bk


    Yes, AFAIR from the report, while the online options were "cheaper", the offline options were only marginally more expensive, like depending on which option, who a few million to 20 million extra. A relative pittance in the scheme of transport projects, even if costs have increased since the report.

    I'd also question if it would really end up more expensive. The added cost of the offline options was the increased CPO cost of having to buy homes beside the line to do it. However once complete, surely that CPO'd land would prove very valuable for a nice high apartment building or two next to a Metro line. It could help pay for itself.

    There is also probably an argument about the cost of congestion and runing costs for a bus replacements over a longer period.



  • Registered Users, Registered Users 2 Posts: 796 ✭✭✭loco_scolo


    Think there's an argument (or accepted fact) that catchment area/radius is linked to the quality of service. An enhanced service naturally draws people from a wider catchment by virtue of being a better service.

    A GL upgrade to fully automated, higher capacity, higher speed, fully segregated Metro direct to the airport, Swords, DCU etc and better interchange with Dart should widen the catchment area.

    But we're talking semantics really!!!



  • Registered Users, Registered Users 2 Posts: 1,365 ✭✭✭Busman Paddy Lasty


    You must have a sixth sense or something 🤔

    Sure have a look at the original Metro North Drumcondra Station. Well away from the canal and offline to the main road. It has a wide open plaza, if I'm not mistaken. All are benefits over a station under the main road that wouldn't be generally accessible never mind a plaza entrance for aesthetics and to allow people flee in an emergency.

    If the actual plan for a Drumcondra station wouldn't go near the main road with a bargepole it says a lot.

    There's a section of path outside existing Drumcondra Station that's only 2 metres wide. I'd consider that a Con in relation to bringing additional services and passengers to the area.

    Under main road was assessed and it appears quickly ruled out for reasons many folks have repeatedly brought here on this board.

    1000000976.jpg 1000000977.jpg

    Professional planners and engineers tasked with building a Drumcondra Metro station, easily eliminated the under main road location for reasons above. Many posters have stated same on this board no less.

    Even demolishing a beautiful building that houses a support centre for the deaf was considering better than going under the main road.

    And closure is not a case of "halving" the capacity, it's removing it entirely. That should not be done without a proper plan to mitigate the knock on effects. Three years of replacement buses is not a plan,it's an excuse for not planning.

    N11 Luas is not a real solution to this, given for the vast majority of this line, a Luas on the N11 is no where near theem. If the catchment area overlapped so much that it was a meaningful alternatiive form of transport, then building the Luas at all would be madness.

    I'm actually in favour of this upgrade, but it's not without pain, and it's not needed in the immediate term. We can argue about how these problems can be mitigated, but pretending they don't exist is pointless.

    That it is not needed right now, is not how you plan for infrastructure. If it is needed in 2040, then it realistically needs to go to public consultation and discussion by 2030, given the rate at which we build things at pressent.

    Catchment is a propery of the line, not the service on it. If you live near any of the southern green line stations, the access you have to destinations along the line does not change whether that line is Luas or metro. Metro upgrade does not increase catchment, but that's okay if all we need is more capacity because it does increase capacity.

    Currently these commuters won't have access to a direct connection to Tara st. onwards, they would do post a Metro Upgrade. If the Bray Luas happens before then, as it is likely to, then a Metro Upgrade could provide a direction connection along that spine to the North. Metro Upgrade would change what would be a 3-4 modal journey for folks currently, to a 2 modal journey. This meaningfully changes the types of passengers who utilise the service. In other words it increases the catchment of passengers whom this service would benefit.

    A Metro upgrade is not just a capacity upgrade, it is creating a new route where there was none before, as both Busconnects, and Dart+ do.



  • Registered Users, Registered Users 2 Posts: 2,762 ✭✭✭KrisW1001


    It's untrue to say that someone living near a green line station has no access to Tara St. They do: change at Charlemont - it's under 100 metres. I'm not disputing that a no-change option is superior, but the alternative to a metro all the way is not "no connection at all"

    I'm not disagreeing about starting to plan an upgrade in 2030, I only said it wasn't necessary to do so in 2020, when Metrolink was designed.

    The post you're arguing with didn't advocate the N11 route at all. Since mentioning that, I also proposed an alternative option of a new aligninment to Beechwood being put in place before starting the tunnelling, as this would at least keep Green operational end to end for longer than was planned in the 2019 plan.

    I said that starting this without an adequate high capacity alternative service would be extremely damaging, and I stand by that. Can we discuss how that alternative can be done? I am in favour of this extension, but it has to be done in a way that doesn't create total chaos while it's being built.



  • Registered Users, Registered Users 2 Posts: 132 ✭✭Brightlights66


    Busman Paddy Lasty, thank you for reminding me of the above, which I will surely have read at the time that MetroNorth was proposed.

    I think it is fair to give some historical context to the text quoted in your post, particularly for newer readers, to help people understand my position.

    When that text was written there weren't even emerging plans for the LUAS cross-city, it was all about the DU project and the metronorth, and the idea of trains going through the Phoenix Park tunnel and using the Midland Line was being actively resisted by IE. The Broadstone-Broombridge corridor was completely idle, without any apparent plans for if or how it might be used.

    The plan, at the time, was that Drumcondra would be an interchange between metronorth and the proposed Greystones-Maynooth DART (the proposed Howth/Malahide-Sallins DART would interchange with metronorth at St. Stephen's Green).

    The then metro planners, the RPA, had set their sights on such an interchange at Drumcondra. I would be interested to know if the document you quote has any assessment of the various station construction opportunities at Glasnevin. The RPA had set their sights on an interchange at Drumcondra, even to the extent that they built the early stages of a station at the Mater Hospital - pointing directly in the direction of Drumcondra - with a view to that happening, even prior to getting a railway order.

    (That partial station box at the Mater and a metronorth station actually at or very near Drumcondra would have been quite close, possibly another factor in choosing a location north of Drumcondra station at St. Joseph's Avenue).

    That was the context, back in 2005/6, when the metronorth and DU plans had been formalised, and would go on to get unswerving approval from ABP.

    The Crash then came, and the plans became more modest. The PPT and Midland line were opened to regular passenger traffic, the cross-city LUAS was built, and who knows what happened to the station box at the Mater.

    The puzzle I struggle with is why Ireland would, with Metrolink, essentially dust off an old plan for a metro between Swords and the City Centre and move it pretty much adjacent to a LUAS line that didn't even exist when planning permission for it was obtained the first time. (Of course, I fully accept that this plan is different to metronorth, but it's still a city centre-Swords metro).

    From the river to the Royal Canal, the proposed metrolink is almost in its entirety 300-500 metres away from the Green LUAS. At present, the LUAS corridor (which would be capable of taking a metro) runs 8 trams from Broadstone into town at the 8-9 am peak, roughly a tram about every 7.5 minutes, according to the timetable. Can it really be justified to do very expensive tunnelling for 2 km or so, between the river and the Royal Canal, effectively adjacent to such an underused corridor?

    It really shouldn't be beyond the powers-that-be to move metrolink eastward from there, make a few local changes, and remove this duplication problem while achieving the same connectivity.



  • Registered Users, Registered Users 2 Posts: 1,365 ✭✭✭Busman Paddy Lasty


    My post concerned our prior conversation about the main road being unsuitable location for a Drumcondra underground station.

    You made it about Glasnevin again. Get some help man ffs!



  • Registered Users, Registered Users 2 Posts: 1,450 ✭✭✭Consonata


    You repeat the same points over, and over again, and have done for nearly a decade now. The reason's why Drumcondra was a rubbish interchange has been well articulated to you.

    And there is no station box under the Mater. There is a reinforceed wall and not much else.



  • Registered Users, Registered Users 2 Posts: 796 ✭✭✭loco_scolo


    I've posted this before but you conveniently ignored it and still quote "300-500 metres", which is absolutely false. Maybe this time you'll acknowledge that you're wrong?

    Minimal difference between the routes. Drumcondra still maintains a Dart connection. A new Metro/Dart station added at Cross Guns with direct interchange between Metro and TWO Dart lines.

    Loco Scolo, with respect, I did not 'conveniently' ignore your post.

    I saw it, and noted what you wrote.

    But what you are doing here is showing the distances between the stops on the LUAS in that area and the proposed stations on the metrolink in that area, and your figures seem to be correct.

    What I am saying is that the two lines are broadly 300-500 metres apart (for example, on the metrolink between the proposed Mater station and Glasnevin, at Phibsboro, the metrolink and LUAS would be about 450 metres apart, and at the Cabra stop, again just 450 metres from the proposed metrolink at Glasnevin).

    There is a fine, recently built overground LUAS line which brings people rapidly from the Royal Canal into and out of town and to other connections, on a corridor which would itself be well capable of carrying a metro, albeit presently with just a tram around every 7.5 minutes at peak times. That is, seriously underutilised.

    It is proposed to do expensive, parallel tunnelling in that area to build a metro which is, broadly, just 500 metres away from that LUAS and will have a service every 90 seconds. I feel sure that will significantly affect the LUAS catchment, and I really can't see that it is the most efficient way to use Ireland's transport expenditure.
