    I'm not even vaguely confused here, thanks.

    Every single fuel cell train product falls in to the solution looking for a problem box. They are all failures, and were failures the second before they launched. We have 50+ years of knowing they're failures behind us.

    I'd also question how many of those are "on offer" - I suspect absolutely zero of them could be obtained for testing outside of the companies labs; whereas multiple companies are trying the combustion option - and finding out that its a terrible idea too - outside of company labs.

    You can discount any fuel cell train as a subsidy sucking joke, not a real project. Fuel cells are a dead end technology; there won't be a market for trains, cars, trucks or buses using them going forward - which we've known for 50+ years - they aren't new!

    There might be some market for hydrogen combustion for very specific purposes; but it won't be trains either. However, there are at least slightly more serious projects trialling it - but they'll fail too. While emitting NOx.

    Sorry, but you are just completely wrong about this!!

    The first Hydrogen Fuel Cell trains entered commercial passenger service in Germany back in 2018. That line has now been completely converted to HFC operation with 14 HFC trains in operation on the line (Alstom Coradia iLint):

    A total of 27 trains are to be delivered by Alstom by next year:

    Stadler Flirt H2's first HFC train just entered commercial passenger service in California on the Arrow service just last month:

    https://rollingstockworld.com/passenger-cars/the-first-flirt-h2-hydrogen-train-from-stadler-enters-commercial-service-in-usa/

    These are real trains, delivered to customers and in active passenger service, not just some prototype!

    I'm not aware of any Hydrogen Combustion trains in commercial passenger services. Though I'm aware that it is something some freight operators in the US are playing with.

    Hydrogen Fuel Cells aren't a new technology, we have 3 HFC buses with BE for a few years now and there are 20 or so up in Belfast.

    Now those buses here and trains in Germany have had plenty of issues, I'm not sugar coating the issues that HFC vehicles are having, but lets not make up inaccurate nonsense, they have enough issues without doing that.



  • Registered Users, Registered Users 2 Posts: 75,488 ✭✭✭✭L1011


    The flywheel Parry People Mover is a train in actual service. Doesn't make it an actual viable technology.

    Fuel cell investment is throwing good money after bad. I'm pretty sure combustion is going to end up exactly the same.



  • Moderators, Motoring & Transport Moderators, Technology & Internet Moderators Posts: 24,122 Mod ✭✭✭✭bk


    Sure and I've my own very strong doubts about HFC trains, but lets talk about it using actual facts!

    I'm happy to discuss the issues that the HFC buses BE and Translink have or that the German HFC trains have had. But we should do so from a position of facts on the subject.

    Bordeaux’s trams are a little different in that they do run without wires in some parts, but not by using batteries. Instead there’s an electric rail underneath the tram which feeds it electricity.

    More information on the system used in Bordeaux here: Alstom APS - Wikipedia.

    In summary, there’s a “third rail” but it’s only energised when the tram signals that it’s over each short power-supply section. This avoids the obvious issues of embedding a live conductor into a street surface. It’s safe, but it’s more expensive than overhead wiring, and it has efficiency issues in rain. In our misty, rainy climate, I think damp would be a bigger problem than the costs, but it could still be useful for short sections where overhead wiring is difficult to install. (Barcelona uses a mix of overhead and ground power on one of its lines using version of the same trams that operate in Dublin)



  • Registered Users, Registered Users 2, Paid Member Posts: 41,282 ✭✭✭✭Hotblack Desiato


    I'm sure I can't be the only person who has no problem whatsoever with Luas overhead wires in Dublin city centre. Bring it on, it's not like we didn't have a lot more tram lines in the past…

    The "mini-stonehenge" random equipment boxes all over the place (not just for Luas) are much more of an issue tbh. Overhead wires don't get in the way of pedestrians. Far too many signposts and poles around too.

    I'm partial to your abracadabra
    I'm raptured by the joy of it all



  • Registered Users, Registered Users 2, Paid Member Posts: 1,514 ✭✭✭riddlinrussell


    Don't most European cities solve th "stonehenge" issue by putting those services in underground boxes?

    Yes hydrogen has a potent greenhouse effect - one of the industry's dirty secrets. It's not directly a greenhouse gas (it doesn't linger because it's highly reactive) but the way it reacts with other elements of the atmosphere means it causes global warming. Most recent studies have calculated its GWP100 (100 year warming potential) at somewhere between 11 and 13 times that of CO2.

    The "so clean it produces water when burnt" is another lie or distortion - it only produces water if burned in pure oxygen which is a completely theoretical situation. When burnt in actual air, the high temperature causes nitrogen in the atmosphere to react with oxygen producing poisonous nitrous oxides. There is a proposal and (shockingly still being lobbied for) to add hydrogen to the piped natural gas mix for domestic consumption - even while analysis shows that with a 15% hydrogen mix, the amount of NOx produced by your gas cooker or boiler increases 10-fold. NOx causes a multitude of harms to human health - particularly children (growing up in a home with natural gas cooker increases a kid's chance of developing asthma by 40%); now consider the effect of multiplying the amount of NOx by 10.

    The thing to remember about hydrogen is that despite the talk of "green hydrogen", after decades with 10s of billions of investment, 97% of the hydrogen consumed is still produced by dirty means (from fossil fuels). The hydrogen industry's sales pitch is something along the lines of "ah sure start using hydrogen now and we'll figure a way of making the clean stuff economically sometime in the future but when that day comes, you'll be ready!" So any increase in hydrogen consumption today, will actually increase fossil fuel consumption (the principle mechanism used to produce hydrogen).

    The big players in the hydrogen industry are, without exception, fossil fuel companies. They're flogging old rope - there were hydrogen "boosters" trying to push hydrogen into the energy sector since the 19th century, the first hydrogen vehicle prototype was in 1810, fuel cells were commercially available in 1930s, electrolysis has been around since the turn of the 18th century, etc. There is nothing new at all about modern hydrogen tech - it's the same stuff that failed to find a use for the last 2 centuries but has now found a use as a mechanism to lever subsidies out of gullible and naive governments.

    And all this might not be a deal-breaker but, in addition, you have: massively inefficient as a form of electricity storage, horrifically dangerous to handle, expensive to store and transport, difficult to contain - it's the leakiest gas known to physics, etc.

    I generally dislike the term "greenwashing" but if there was one example where the term is 100% applicable it would be with the way the likes of Chevron and Shell are lobbying to have hydrogen projects included in "green" programs so they can get their hands on subsidies and grants.



  • Registered Users, Registered Users 2 Posts: 2,599 ✭✭✭Economics101


    And don't forget that even if you produce "Green" Hydrogen by electrolysis using electricity generated from wind/solar/wave power, there is a 30% loss in terms of the electricity-input versus the hydrogen-output. All that makes straingtforward electrification prima facie superior to hydrogen.

    It seems that there is a phobiia in Ireland about putting up OHLE.

    Straightforward electrification is better, the problem is storing it. If you have sufficient storage then you could generate green electricity from solar in June and burn it at Christmas.



  • Registered Users, Registered Users 2, Paid Member Posts: 1,514 ✭✭✭riddlinrussell


    For trains I think, especially with the development of the technology in the last decade and anticipated future trajectory, battery has got to be the no brainer as a stopgap to full OHLE, you could set it up to have OH charging at each station, so you're not running it the full line every time you 'electrify' a line, and then tie those OH setups in as you install line, you could even do a phased roll out station to station of the main wires and not have to do it as a 'big bang' project in one go.

    The JR is not shut down - it is continuing but is effectively now a claim for damages by CAF.



  • Registered Users, Registered Users 2, Paid Member Posts: 3,300 ✭✭✭KrisW1001


    I can see why CAF is trying for damages - this is a big loss for them, as I think it’s obvious that this contract is effectively a pilot for IE’s whole fleet replacement over the next 10-20 years.

    With luck, the FLIRTs will work well, and can be used for Cork-Dublin next: the carriages there are 20 years old, but the locomotives hauling them are have around 30 years on them. Plus, the Mallow-Cork stretch is going to be electrified as part of the CACR programme in the same timeframe, so a hybrid train would make a lot of sense.

    The train tender specified 1500 V and 25 kV overhead plus diesel power, which would allow them to run anywhere on the island with current and future electrification plans (Cork, and everywhere else outside of Dublin looks likely to be 25 kV, Northern Ireland will definitely be). The tender also said “capable of 180 km/h”, but Stadler only provides two FLIRT models, with maximum speeds of 160 and 200 km/h so it looks like they’ll be the faster models, again aligning nicely with the plans for the rest of the network to support 200 km/h running.



  • Registered Users, Registered Users 2 Posts: 4,657 ✭✭✭goingnowhere


    Spot on, but that only really would apply if the contract had a large option for additional orders…

    The spec requires 1500V+battery + diesel/25Kv, i.e you can have diesel OR 25Kv but not at the same time as the transformer goes where the fuel tank is



  • Registered Users, Registered Users 2 Posts: 10,552 ✭✭✭✭cgcsb


    I wonder why IÉ specified 180km/h when they plan to effectively puild a brand new intercity route between Connolly and Drogheda, surely they'd design the new route to be 200kmh+ capable given that it's track dedicated for Enterprise, with perhaps some express Newry/Dundalk commuters.



  • Registered Users, Registered Users 2, Paid Member Posts: 3,300 ✭✭✭KrisW1001


    The contract has no option for additional orders, but the winning bidder for this one is at an advantage for further purchases, because supporting just one kind of train is way easier than dealing with multiple kinds. This will be Stadler’s first train on a 1600mm gauge, although according to Wikipedia have already provided FLIRTs for customers in Finland (1524 mm) and the Baltic states (1520 mm).

    The tender spec is a minimum, and it seems that Stadler’s offering meets it, while offering more flexibility. The FLIRTs are principally an electric family, so the diesel power option comes from adding a self-contained “Power-Pack” section to the train, comprising the diesel generator and fuel tanks. When diesel is no longer needed, this additional module can be removed, but the use of a separate module means it does not steal space from anything else in the regular train. The necessary transformers for bi-voltage operation appear to be accommodated in the normal train design, and batteries seem to be roof-mounted (although no battery-equipped FLIRT is capable of the 180 km/h speed requested in the spec; all are 160km/h even on OHLE). As a result of this design, it should be possible for these units to operate on any of 1500 V DC, 25kV AC, or diesel power. That’s an ideal combination for use anywhere on IÉ’s network as it gets electrified.



  • Registered Users, Registered Users 2, Paid Member Posts: 19,634 ✭✭✭✭LXFlyer


    Just because something is in the AIRR doesn’t mean it’s going to happen.

    At the moment the focus is on options for expanding capacity on the existing route.

    Any new build railway line such as you are describing is, I would suggest, decades away and probably wouldn’t happen until after this rolling stock needs replacing.



  • Moderators, Motoring & Transport Moderators, Technology & Internet Moderators Posts: 24,122 Mod ✭✭✭✭bk


    In another thread it was mentioned that the requirements were for a minimum of 177km/h running, but 200km/h preferred. The FLIRT 200 that these are based on are a 200km/h design, so I'd assume these are capable of it, though perhaps only in the pure EMU mode.

    Also I'd agree these will likely be in a strong position for a future Mark 4 and eventual ICR replacement if all goes will.

    From the railway gazette website linked previously...

    Two diesel engines will be installed in the driving vehicle at one end of a unit, creating a power car and avoiding the use of underfloor engines. Whilst both engines will normally provide power, it is expected that a single engine will be capable of delivering sufficient traction to maintain performance in the event of any failures.

    So not a power pack, it would seem.



  • Registered Users, Registered Users 2, Paid Member Posts: 3,300 ✭✭✭KrisW1001


    Not well explained, but that's what Stadler's "Power Pack" is.. a short power car, bogie at each end, that can be added to or removed from the train configuration. This contains all of the diesel generator equipment, and it feeds electrical current into the train. Because it's encapsulated in its own module, doesn't displace anything from the "plain" EMU. There's no other option for diesel power in the FLIRT range.

    There are two engines in that car, but they're generators, not traction motors. The motors are all electric, because FLIRT is an electric train model.



  • Registered Users, Registered Users 2, Paid Member Posts: 94 ✭✭DrivingSouth


    I know what a power pack is. You're implying they are describing the same thing but badly. They literally said

    Two diesel engines will be installed in the driving vehicle at one end of a unit, creating a power car

    You seem to be describing different things. I've no idea which is right. We'll (not so) soon find out



  • Registered Users, Registered Users 2, Paid Member Posts: 3,300 ✭✭✭KrisW1001


    I don’t know why you’d imagine that Stadler would ditch a tried and tested solution to come up with a brand new diesel motive solution for just eight trains for a single, small, customer. It’s a Power Pack. There are two engines that drive generators, and the generators provide power to the eight motors on the train.

    The “DMU” FLIRTs sold to the Dallas DART in 2020 use the same architecture, but without the 1500 V OHLE. The FLIRT trains are an EMU family, but some are fitted with optional on-board generators.



  • Moderators, Motoring & Transport Moderators, Technology & Internet Moderators Posts: 24,122 Mod ✭✭✭✭bk


    So the FLIRT 160’s have the concept of a separate PowerPack car that sits between the carriages and contain the Diesel engines or Batteries depending on spec selected.

    But it looks like we aren’t getting that, instead we are getting a train based on the FLIRT 200 design. The 200’s don’t seem to be compatible with the 160’s PowerPack car design, so instead the Diesel gen will be placed in the driving car thus creating a power car up front. I’ve read elsewhere that the batteries will go on the roof.

    The FlIRT 160 are more regional trains, they only come with a maximum of 4 carriages (5 if you want to include the PowerPack) and are limited to 160km/h. So they aren’t suited to intercity service. The FLIRT 200 are their intercity model that can have far more carriages and get up to 200km/h.

    Yes, this will be a unique design for Stadler, they haven’t done a FLIRT 200 with Diesel generators before.

    While yes 8 trains isn’t a big order, I think Stadler are jumping at this as they see it as a possible growth opportunity for both here and the UK. I believe they had previously offered this design in the UK for a previous competition, so they may have already done much of the design work for it. If this works well, then these could be a strong competitor for the Mark 4 replacement, eventual ICR replacement and might also find favour across the UK.

    Yes, this design is a very exciting development in the trains available. Having the power cars at the end, will also make a much more enjoyable journey for the passengers on board. I have travelled on a few FLIRT trains around Europe and they are quite nice indeed.

    They will know that Irish Rail will need a full replacement for the Cork line trains and really in time offer a more premier IC service as the ICRs continue to get hammered doing all sorts of work. It is a great foot in the door for them.



  • Registered Users, Registered Users 2 Posts: 9,127 ✭✭✭Markcheese


    Is there much point in specifying a new line to be 200 kph to future proof it , when it's a relatively short stretch , with a couple of stops ( you'd hope ) , as in if there are stops on a shortish run how much time could the train really spend at 200kph , to save a minute or 2 per full journey , versus the cost of specing the line to 200kph ,

    I'd rather the money was spent on making the alignment side enough, and the bridges wide enough to expand the number of tracks at some distant point in the future .. if necessary,

  • Moderators, Motoring & Transport Moderators, Technology & Internet Moderators Posts: 24,122 Mod ✭✭✭✭bk


    That is the advantage of 200km/h over true high speed rail 300km/h TGV.

    TGV trains are much heavier, which means they have slow acceleration speed out of stops, so if you have a route that is relatively short and with stops they rarely get up to 300km/h. On the other hand 200km/h trains are much lighter so they tend to have very good acceleration speed out of stations, better then TGV, so they can get up to 200km/h pretty fast and stay at that speed for longer.

    This is why both Switzerland and Netherlands have opted for 200km/h too, is suits smaller countries with more frequent stops.

    I don't think there is any major extra cost is specifying 200km/h, 200 has basically become the default for non TGV intercity trains. Take the Mark 4, they are actually 200km/h compatible, it is just the locos that are limited to 160km/h.

    I do think 200 is necessary if you want to get to the 90 minute journey time between our cities that IR is targeting, it wouldn't be just a 2 minute difference.

    BTW I really don't think most of our intercity network will need quad tracking, we are aiming for 30 minute frequency to each city. The likes of Netherlands can do 15 minute or better just fine on double track. Obviously you need to separate out DART, but it should be fine outside the cities. Also keep in mind the faster speeds also has an impact on frequency and track capacity. The main reason the Japanese invented high speed rail was to actually boost the capacity of the lines, not actual faster journey times, that was just a nice side effect. The faster you can make the journey, the faster you can turn the same train around and make the return journey, thus more trips per day per train, but also it means the line clears faster too, so you can send another train.

    Our intercity network is a lifetime away from being congested. What we need to do is double track it, electrify it and speed it up and then we can make the most of it.



  • Moderators, Motoring & Transport Moderators, Technology & Internet Moderators Posts: 24,122 Mod ✭✭✭✭bk


    Yes, it feels like a nice compromise between Multiple Units and traditional loco hauled. I know there have been a lot of complaints about the Class 800 in the UK, with their under carriage engines causing noise and vibrations in the carriages, similar to the ICR's.

    This powercar approach still gives you the benefits of a MU, while keeping the noisy engines up front almost like a loco hauled train. There are of course some trade offs, but might be worth it.

    Thinking about it a bit more, I do at least partly see where Mark is coming from, I do think we have other priorities to get too before 200km/h service, but I do think it is a good long term goal.

    Keep in mind these new trains won't enter service until 2030, that means we will likely have them until 2060 at least. While 200kph isn't a priority I would hope we would be well on our way to it before 2060! And before 2065-2070 for the Mark 4 replacements.

    Most intercity trains start at 200kph from what I see in the market, it seems to be the default for modern intercity EMU's, 160kph trains largely seem to be smaller regional type trains. The Stadler Flirt 200 we are buying are basically designed as a 200kph train by default, I appreciate that in Diesel mode they might only do 177kph, but I think it would be a sin not to spec them to do 200kph once converted to full EMU and I don't think it is much more expensive to spec them like that given their default design.

    BTW My priorities for intercity would be:

    1. Hourly service to all cities, Cork has had it for years and Belfast recently got it which is great, but Galway/Limerick/Waterford should really be hourly too.
    2. Half hourly service to Cork at peak times. It is getting busy enough for this.
    3. Galway/Limerick/Waterford double tracking (or passing loops).
    4. Remove all speed restrictions, consistent 160km/h running.
    5. Electrification
    6. 200km/h service, 90 minutes to every city.

    I'd see 200 being the long term goal that we are gradually working towards.
