    I'd say there is a good chance that Metrolink will open in phases. The way the main construction works are divided into three civil works contracts and then there is a PPP for internal fit out and rolling stock should allow for it. It's not all one big contract like MN was to be.

    The tunnel contract will obviously take the longest time to complete but the other two sections north of the M50 should be completed much quicker. Once the latter sections are handed over, fit out can start there while tunnelling continues further south. Crucially, the depot is north of the M50 so should be handed over relatively early. Once the line north of the M50 has been fitted out and some rolling stock has arrived, I would expect that they would look to get that part operational, even if the tunnel will take another couple of years to complete.



  • Registered Users Posts: 1,343 ✭✭✭Consonata


    I believe the plan currently is to open the Swords/Airport section first and the tunnelled section later. Or at least the Northern section will have test running.



  • Registered Users, Registered Users 2 Posts: 1,364 ✭✭✭bikeman1


    It definitely makes sense to open from the depot at Dardistown North to the end as a section. This would give some testing opportunities for the stock and the stations.

    It would also give buy in for the line as a whole as people can see it is real, happening and will be there.

    Also quite a lot of people in Swords and to the North work in the airport, so this will provide a benefit straightaway.



  • Registered Users, Registered Users 2 Posts: 13,972 ✭✭✭✭Zebra3


    if you are in government and it’s possible to open that first section, you’d be utterly mad not to.



  • Moderators, Science, Health & Environment Moderators Posts: 5,186 Mod ✭✭✭✭spacetweek


    It has always been likely that Metrolink will open in phases and 2035 always seemed very padded to me. Possibly that is when the furthest south section will open but I'd strongly assume Swords-Airport will open way sooner than that due to it being a simpler build.



  • Registered Users Posts: 219 ✭✭Bsharp


    Haven't seen any mention of a phased opening in the market sounding or information provided by TII to date. Maybe I missed it. It'll be an important consideration for the M500 package at tender stage so that they can design and sequence works accordingly, and order the rolling stock.



  • Registered Users, Registered Users 2 Posts: 11,438 ✭✭✭✭salmocab


    I hope it’s opened in phases just to hear people complain that it was a waste of money if it’s not instantly at capacity.



  • Registered Users, Registered Users 2 Posts: 7,678 ✭✭✭prunudo


    Obviously there would be some uptake but would there be much trip generators from opening north of the m50? I suppose it would be good to test the system when demand isn't so high.



  • Registered Users, Registered Users 2 Posts: 1,852 ✭✭✭KrisW1001


    It would certainly make sense as a ramp-up test to open the overground sections first and shake out any bugs in the system before the high traffic section begins service.

    Politically, there would be a lot of support for such a move too... there's nothing like cutting the ribbon on something expensive to show a government is making "progress".

    I wouldn't expect it to be something mentioned in the high level information available to the public. Undoubtedly the two civil contracts from the M50 north will be completed first so it makes sense from everyone's perspective to progress with fitting these out before the tunnel is complete. Once the civil works are completed, TII will want to hand them over to the PPP company, otherwise they are liable for securing and insuring the site.

    Rolling stock will go into production soon after award of the PPP (after detailed design is completed and signed off). Obviously sets will be completed in batches over several years. The manufacturer won't want to have completed stock sitting in their facilities for years, they will want to get it to the depot at Dardistown as quickly as possible (and their pricing will almost certainly be based on that). They will certainly be bringing to operationally ready and testing and commissioning the new systems before the tunnel is completed (trying to do everything at the end would be a huge risk).



  • Registered Users Posts: 219 ✭✭Bsharp


    The two control centres are on that section so testing and commissioning makes sense. However, there's a big difference between that, and opening to the public for services. The operator would lose money doing it. If it's TIIs intention then they need to express it, so tenderers can factor it into their financial models.



  • Registered Users, Registered Users 2 Posts: 9,371 ✭✭✭markpb


    I assume the operate contract will be similar to Luas where the fee paid to the operator will be based on performance, not fares revenue.



  • Registered Users, Registered Users 2 Posts: 11,438 ✭✭✭✭salmocab


    Also months of using the systems on a shorter quieter section could only be good for getting all the staff up to speed on things, meaning when the rest opens there are already experienced staff working not just trained staff.
    It makes sense to me if it’s logistically viable to do it.
    as I joked above it will cause outrage among the people who get outraged by everything but that’ll happen no matter what.



  • Registered Users, Registered Users 2 Posts: 1,852 ✭✭✭KrisW1001


    I wouldn't be certain they'd lose money on that section if it was Estuary-Northwood (i.e. including the short underground section at the Airport). I expect that ML will be very busy on all sections from opening day(s).

    The enormous latent demand for mass transport in Dublin: look at how both DART and Luas were given capacity increases almost from launch (In DART's case, more cars were ordered within 24 hours of first passengers being carried). I don't see ML being different.

    Also, early opening would help the case for a second line. I think people in Dublin don't realise how much they really want a Metro network. Seeing a line in operation makes it very easy to imagine the same thing serving your own neighbourhood... and people who until now didn't care will start asking their TDs why their part of the city is getting left behind.



  • Registered Users, Registered Users 2 Posts: 1,364 ✭✭✭bikeman1


    I'm not sure that Northwood - Dardistown would be an easy one to do early on. I presume where the tunnel comes out and looking at the documents, will be an important and busy construction site while the TBM is working its way to Charlemont?

    Dublin Airport is a massive trip generator in all directions. I could envisage someone being dropped to Estuary or Swords Central to hop on the Metro straight to the centre of the airport in a few minutes. Far less hassle than trying to get in all the way to the airport.

    Motorways are often open in sections, it makes now sense to not push on with testing, trailing, training staff and the system before the big launch into the city section.

    From experience, its clear metrolink will be exceptionally busy from day 1 and will hit capacity well ahead of forecasts. Latent demand for good transit is severely underestimated in all traffic models, not just in Ireland but globally. So many trips are avoided/delayed because of the 'hassle' it would involve at present. At the moment if you fancy going to from Swords to the south city centre for non work purposes, your best option is to just not, who has time for a 2 hour round trip.



  • Moderators, Science, Health & Environment Moderators Posts: 19,989 Mod ✭✭✭✭Sam Russell


    Just as congestion and awkward changes to routes causes traffic to evaporate, so making travel easier or cheaper or more reliable causes an increase in use.



  • Moderators, Science, Health & Environment Moderators Posts: 5,186 Mod ✭✭✭✭spacetweek


    Regarding the lack of a mention of phasing in metrolink planning, experience abroad shows that when a Metrolink takes a long time to build, they only decide on a phased opening towards the end, as some sections reach completion sooner than others, or unexpected snags are hit.



  • Registered Users Posts: 655 ✭✭✭loco_scolo


    The Metro Blue Line 4 in Milan is an excellent example. It's Milan's 5th Metro line, but first fully automated driverless.

    The first 6 stations from Linate Airport to Dateo (regional rail) opened in November 2022, with 2 additional stations opening in July 2023 to connect with Metro Red Line 1. The final 13 stations, with two Metro interchanges (Lines 2 and 3) are due to open in October 2024.

    The stretch from Linate Airport to Dateo benefited from regional rail connections at Dateo, but was reasonably quiet anytime I used it. Probably served as good testing to iron out any issues. For example, a few times I used it the platform doors were not perfectly lining up with the tram doors, but seems to be fixed now.

  • Registered Users Posts: 655 ✭✭✭loco_scolo


    It's also a quarter of the cost of Metrolink per km. It's 15km long with 21 stations, all underground and all constructed with cut and cover.

    Hopefully the same company can price Metrolink!!

    ... at Italian wages, buying properties at Italian prices, in a country where they've been digging, bridging and tunnelling for two thousand years, give or take, so there's lots of competition for any project. Being on the continent helps a lot: all of the materials and specialised plant can be brought overland. Just getting stuff here costs far more.

    Also in Italy, the infamous Roma Linea C is also very similar to Metrolink and Milan M4 for most of its length, and most of its stations are actually open. It's only the four stops around the old Roman Forum that have delayed the project so much..this was expected, and I posted a video about it a few pages back that shows just how big a job it is.



  • Registered Users, Registered Users 2 Posts: 7,143 ✭✭✭Pete_Cavan


    Posters here have brought up the cost of that metro in Milan before but they were using costs from more than a decade ago, ignoring the huge cost increases since then, costs which didn't include rolling stock, etc.



  • Registered Users Posts: 655 ✭✭✭loco_scolo


    Ah now I'm not suggesting we can build Metrolink for a quarter of the cost! It's a very relevant example of a similar line still under construction. The only point is that maybe the "unknown unknowns" are horsecrap (which they are) and Metrolink costs will stay within the expected range, hopefully on the lower end.



  • Moderators, Science, Health & Environment Moderators Posts: 19,989 Mod ✭✭✭✭Sam Russell


    Unfortunately, the media (IT I'm looking at you) will take an estimate of from €3 to €7 billion as €7 billion and that will become the quoted cost.

    The next round of discussion of cost will have politicians opposed to the project quoting €13 billion because of 'rising costs and inflation'.

    Now we have the figure of €13 billion being the accepted cost, and this is before a single request for interested parties to seek qualification.

    Now will any bidders come in at €7 billion, even if that is possible?



  • Registered Users, Registered Users 2 Posts: 7,143 ✭✭✭Pete_Cavan


    Metrolink won't be built under a single contract so there won't be one figure presented to government. The total cost will be the accumulation of multiple tenders, the biggest of which will be the PPP and it will be paid over 25 years.



  • Registered Users, Registered Users 2 Posts: 6,188 ✭✭✭Elmer Blooker


    It isn’t like it hasn’t been done here, the Dublin port tunnel which is in fact two tunnels with a combined length of 9.2km or 4.6miles was done in only five years (2001-06)

    It has been done and can be done if the will was there which it isn’t.



  • Registered Users Posts: 10,673 ✭✭✭✭MJohnston


    Regarding potential phased opening, presumably you could even do it station by station as the TBM proceeds south — does anyone know where turnback facilities would exist on the completed line?



  • Registered Users, Registered Users 2 Posts: 1,328 ✭✭✭p_haugh


    Only at the airport (and dardistown using the depot tracks I guess). The airport turn back is just north of the station, and only links to each tunnel in the southbound direction

    Not sure if there's any planned further south.

    Now, saying that, I would imagine it would be trivial enough to add temporary switches outside stations if the demand for it requires, especially if they're opening it in phases at a reduced frequency.



  • Registered Users, Registered Users 2 Posts: 10,961 ✭✭✭✭tom1ie


    Does anyone know where the deepest point on metrolink will be?



  • Registered Users Posts: 219 ✭✭Bsharp


    The three sections can potentially have three different contractors, M401, M402 and M403. Then there's an M500 systems contractor that looks after the track, power and everything across the whole route. Any potential phasing would need to make sure the necessary contractors are in sequence. From M500 perspective, you won't want your track and systems design and build being stop start as they're international skills and expensive to mobilise and retain.

    The M4 metro was mentioned above, think it was one Contractor overseeing everything which makes phasing alot more straightforward, open to correction on that.

    No, it's not possible, the debris from the TBM mining is going to be conveyored out through the entire tunnel, so the tunnel will be entirely off limits for testing/phased opening.



  • Registered Users, Registered Users 2 Posts: 7,143 ✭✭✭Pete_Cavan


    M500 is the PPP which basically includes everything apart from the civil works. There is so much wrapped up in it and it will be for the company themselves (a JV between numerous huge international companies) to schedule all the various elements. You could have a company like Siemens and they will be involved for the full 25 years, it's not like traditional subcontracting where you bring in someone to do something and they are gone once that's finished.

    The M500 contract will have to be awarded early as a huge amount of work for it will be happening in parallel with the civil works, it just won't be happening on site. There will be a huge amount of design work and approvals, then procurement and production of necessary items happening while the civil works are ongoing (the rolling stock will be years in production, all the ducting, ventilation equipment, transformers, etc. will be made specially for the project, even off-the-shelf items will be a "job lot" specifically for this project, they wont just hoping there is enough stock available when it's need, particularly given how fragile supply chains can be).

    The PPP company will have paid hundreds of millions in down-payments, they will be monitoring the civils contracts and will want to get the two above ground sections as quickly as possible. They'd love to get going at the sections north of the M50 a couple of years before getting into the tunnel.

    I'm sure the intention is that M401, M402 and M403 will have three different contractors. The scope of the works is so big that they want to utilise the resources of multiple contractors, that's why it has been split into three packages.

    John Laing Group eyes Dublin Metro plan

    Infrastructure investor interested in backing rail link between city and airport

    Wed Apr 10 2024 - 08:30

    I didn't read the article because I don't have a subscription but the IT seems to be saying that Jones Laing Group are interested in 12kms of the 18km Metrolink.

    I wonder why Jones Laing don't seem to care (at least according to the I.T.) about the remaining 6kms and 4 additional stations from the Airport to Fosterstown, Swords Central, Seatown and Estuary Park and Ride beside the M1 Motorway.

    Maybe it's just that the I.T. Ranelagh readership wouldn't know about anywhere or anyone north of the airport and so the I.T. just forgot or didn't care to report on the full project. Or maybe Jones Laing themselves have never been north of Dublin Airport and are just not interested.

    Can anyone with access to the article shed any further light?



  • Registered Users, Registered Users 2 Posts: 70,172 ✭✭✭✭L1011


    The article says to the airport, and then claims it's going to Malahide. bad journalism and/or subediting.

    Nowhere do Laing say they're interested in anything other than the full contract and indeed that's all that will ever be offered as the PPP, you can't operate part of it



  • Registered Users, Registered Users 2 Posts: 9,371 ✭✭✭markpb


    There's nothing extra in the article, it's just a fluff piece about JLG. The comment about the link between the city and the airport feels like it was written by someone who doesn't know/care that the metro will go beyond the airport. It's in the business section of the paper so probably not written by someone with an interest in infrastructure.



  • Registered Users Posts: 97 ✭✭Paul2019


    Thanks guys, I suspected it was the usual inaccurate Irish Times take on stuff.

    There's a reason I unsubscribed years ago.



  • Registered Users, Registered Users 2 Posts: 7,678 ✭✭✭prunudo


    i think a some of blame should be shared by TII, for the duration of this project to date, journalists, even those that know better, have got away with city centre- airport narrative when we all know its far more than that.



  • Registered Users Posts: 1,343 ✭✭✭Consonata


    Tbf to TII, they have stated the benefits of the Swords connection in every single press briefing and spent several hours at the beginning of the oral hearing discussing this.

    I think the degree of obsequiousness shown by Journalists towards bad faith actors, powerful as they are in public discourse, has a far larger degree of the blame in MetroLink getting sandbagged as an airport connection.



  • Moderators, Computer Games Moderators, Recreation & Hobbies Moderators Posts: 10,449 Mod ✭✭✭✭CatInABox


    Dublin People have an article up based on some of the objections to the Metrolink from the oral hearings. Nothing new, or at least nothing new that couldn't have been guessed. No one really needs to read this stuff, but it does include what Rethink Metrolink were talking about (Ranelagh, etc), what one of the residents of College Gate wanted (move the station and have a pedestrian tunnel), and the Charlemont residents (safety concerns over the Luas).

    The safety concerns are hilarious, by the way, if you want a laugh.

    There are a number of international contractors who are only interested in building the tunnelled sections. They're view is that the cut/cover section can be delivered locally and the profit to be gained by them does not outweigh their cost of mobilisation/delivery for the likely win price.

    The article about John Laing was partly because they opened an Irish branch today.



  • Registered Users, Registered Users 2 Posts: 2,023 ✭✭✭shoegirl


    He's not the only person peddling the ridiculous, amateurish "Newtown Plan." ACRA and Dublin Chamber push it too. And it is properly insane. The guy's a retired bus driver, that's his level of "expertise." And I'd hazard a guess this "solution" is one designed down the pub with the likes of McCarthy and McDonald on the back of a serviette.



  • Registered Users Posts: 1,242 ✭✭✭gjim


    Reminds me, indirectly, of that daft McGuckian plan for Dublin from a few decades back which similarly attracted the support of the gullible and ignorant (of how public transport is supposed to work), the odd opposition politician and a few NGO type bodies which should have known better.

    I don't recall all of the details but McGuckian's "genius" was to ignore conventional radial/orbital thinking about public transport routes - I mean who wants to travel in a boring straight line on their daily commute? Instead, Dublin was to be the proud host of the world's first PT system designed around a figure-of-8 rail loop.

    Like our man above, he had no engineering background at all.



  • Moderators, Science, Health & Environment Moderators Posts: 19,989 Mod ✭✭✭✭Sam Russell


    Mod: Can we forget the Newtown attempts at scrapping this plan to replace this project with an ex-bus driver's vision of public transport service.

    If you must discuss this nonsense, do it in another thread or, better still, another forum



  • Moderators, Science, Health & Environment Moderators Posts: 5,186 Mod ✭✭✭✭spacetweek


    The way the article is written, it might have been Mr. Truscott from John Laing who said "from the city to Malahide". So maybe not the journalist's fault, but it should have been corrected by the journalist anyway.

    Right at the end of the article:
