    The NTA have had no interest in buying Tri-axles since at least 2014, long before any hybrid focus came up.

    I don't totally disagree that a myth about Tri-axles solving all issues has developed over time. However the company was looking at buying more until the Recession hit (with Rear-steer which would have helped significantly with running costs) and by the time they were back on their feet it wasn't really their decision anymore.

    But DB bought just 70 VT's between 2005 and 2007. The NTA wasn't formed until 2009, didn't gain their powers until 2011 and didn't buy their own buses until 2014 with the SG's.

    During that 7 year period, DB didn't buy any more tri-axles and bought hundreds of "standard" double deckers in the AX/EV/VG/GT. During that period there was nothing stopping DB buying more tri-axles, but they didn't. I get the impression that DB wasn't all that impressed with them either. Expensive to buy and high operational costs.

    Clearly even DB thought there was only a need for 70 or so tri-axles out of a fleet of 1,000 (pre NTA).

    By the normal 14 year renewal, the first VT's wouldn't be up for replacement until 2019/2020, but then of course Covid hit and the need for such a big bus clearly wasn't there then. By the time passenger numbers picked up again in 2023, we were into the period when they were buying only zero emission buses.

    Having said all that, I do think a small fleet of 100 or so makes sense. Hopefully those Wright ones go into production.

    Well yes, they tested the water in 05 with 20 of them, were generally pleased with them and then ordered 50 a year later. Plans were in motion for another 30-40 for Swords and Bray routes (along with a Water-testing order for the ADL Enviro 400) when the economy began to turn in Autumn 2008 and all orders were put on ice. NTA being formed in 09 is irrelevant, new buses were completely off the menu.

    NTA then took over new orders from 2012 with the GT. They were NOT bought by DB. From 2014 DB began to have more of a say in types bought/spec etc and asked about the possibility of more tri-axles (with rear steer, which would negate most of the operating costs) and were told no and have continued to be.

    Dublin Bus continued to buy the EV and VG class through 2008 and 2009. Something like 170 of them. There was nothing stopping them continuing to buy the VT class during the same period if they wanted.



  • Registered Users, Registered Users 2 Posts: 1,776 ✭✭✭john boye


    They had all been ordered many months before (in autumn 07 in the 08 EV's case). The 09 reg vehicles were all delivered regless in late 08 and weren't regd until early 09, they weren't bought in 09. Like I have said DB was planning to buy another batch of tri-axles before the downturn hit suddenly.

    The last VT was delivered in 07, I would assume they were ordered in 06. They clearly didn't order any more in 07 for delivery in 08 like the EV's.

    Like I have said DB was planning to buy another batch of tri-axles before the downturn hit suddenly.

    So perhaps another 50, brining it up to a fleet of 120 or so?

    I'd have no issue with the NTA buying 100 to 120, if there are suitable, I'm not sure how many routes can actually handle these or how many in total could be usefully in the fleet.

    Sorry I see you mentioned it already in another post above, about 30 to 40 extra. About 100 to 110 total. Also answers my comment below and makes sense for those two routes, thanks

    BTW one point, recently TII gave a presentation about Luas and it was very interesting. They did a detail survey of how many people actually fit on different Luas vehicles at peak time. They had surveyors count the number of people actually on the vehicles and getting on and off at peak times.

    This gave them very interesting real world numbers on capacity.

    I'd love to see DB or NTA do something similar for buses, single deckers, standard double deckers (both a single and dual door model) and VT class (and perhaps trial a Wrights BEV tri-axle if they could and do the same) and actually publish the numbers.

    Even better if we could get similar stats from the Glider BRT's in Belfast.

    I'd love to see the real world peak capacity numbers of each type of bus, in particular over the length of a route (people getting on and off).

    It would be interesting to see how much real world difference these different types actually make.



  • Registered Users, Registered Users 2 Posts: 1,776 ✭✭✭john boye


    The next order was being readied in Autumn 2008 along with a smallish batch of Enviro 400s. The recession wiped all plans out.

    Yes I'd agree that we wouldn't want any more than around 100 or so. Not too many. It's not just some routes that they're too big for, some depots can't handle them either.



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


    Yes, I wondered if the depots could fit them too, specially given how crowded they are now, thanks.

    For an interesting conspiracy, 2014 was when the NTA published their Swiftway BRT plan, that would have covered the Swords corridor and partially Bray corridor that you mention DB were thinking of for the extra tri-axles. Perhaps why they killed the idea of buying more.

    Of course the NTA stupidly then killed the Swiftway plan, so we ended up with the worst of both worlds!

    If Wrights can get them into production, perhaps time for their return.



  • Registered Users, Registered Users 2 Posts: 4,096 ✭✭✭Polar101


    So why aren't tri-axle electrics a thing? Are they too heavy?

    Sorry if this a stupid question.

    Did the NTA not mention investing in high capacity buses such as triaxles in the long term future in one of their reports for Dublin?



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


    Yes, but they don't really go into detail on what that means:

    "Higher Capacity Bus Systems – using larger vehicles or other forms of higher capacity bus, carrying in excess of 3,000 passengers per hour;"

    https://consult.nationaltransport.ie/en/consultation/greater-dublin-area-transport-strategy/chapter/12-public-transport-bus-light-heavy-rail

    Could be tri-axles, could be BRT, doesn't really go into detail. They also mention some routes becoming Luas lines.

    Well in general Tri-axles aren't very popular and not many are built every year. When they started converting buses to BEV, they first started with the easiest one, the single deckers, then moved to the regular double deckers which are by far the most popular and highest selling models (UK+Ireland market). Tri-axles have always been the last bus model they work on as sales tend to be limited, even back in the Diesel days. Just not really a priority.

    Also as you say, there maybe challenges with the batteries, larger, heavier bus will mean it needs more batteries, which not only increases cost, but also you need to find the space to fit them and handle the extra weight.

    Actually you just made me realise weight might be a problem, they might exceed the maximum legal allowed weight for alternative fuel tri-axles buses. The legal limit is 26,000kg, however as an example the ADL Envrio500EV is heavier then that at 27,500kg!



  • Moderators, Motoring & Transport Moderators, Paid Member Posts: 11,911 Mod ✭✭✭✭devnull


    I'd be curious if MCV / Volvo went for a Electric triaxle at some point, they already have the EvoSeti triaxle in a few different lengths in diesel form on Volvo chassis. (example here)

    I think the 27500 kg figure is for the NA version, I can't find a weight listed for the NZ or HK versions. The NA model is almost a metre longer and has a much larger battery (472kWh vs 709kWh or 827kWh), so I think it's pretty realistic for an Irish model to be under 26 tonnes, maybe even lighter.

    However if it still isn't enough, I wonder if this could push the NTA into looking into articulated buses again? They are allowed to be up to 28 or 29 tonnes which gives them more room to play with. Although the routes they are cleared for as well as what depots can take them could be pretty limiting? Also I am not sure if anyone makes BEV articulated buses for RHD markets?



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


    You are spot on! Looks like the Hon Kong ones are 24 tonne.

    https://www.eeb.gov.hk/sites/default/files/en/node5762/Alexander_Dennis_ENVIRO500EV_ENG.pdf

    Though with just a 472kWh battery as you say. To be honest, that battery size seem a bit too small for a city like Dublin for such a big bus. The EW are almost the same at 454kWh.

    While we don't need as much as the NA models, I'd feel you would need a bit more, maybe 500kWh or so for all day operations, unless you only planned to use them at peak times.

    Of course that is all the ADL model, no info on the new Wrights one.

    There is the Irizar ie tram that Aircoach is supposed to be getting for the Dublin Airport car parks. Hasn't arrived yet, but would be one of the first RHD BEV 18 BRT. Will be interesting to see how they go for Aircoach.

    If we were to get BRT's, I'd figure it would be similar to the triaxles. Limited numbers, maybe 100 or so, limited to routes like the Swords road and N11. Would likely need their own dedicated depot or one of the new ones, etc.

    Not saying it is going to happen, just what it might look like.



  • Registered Users, Registered Users 2 Posts: 1,692 ✭✭✭mikeybhoy


    There's a few of them sitting up in McElvaneys Scania in Finglas



  • Moderators, Motoring & Transport Moderators, Paid Member Posts: 11,911 Mod ✭✭✭✭devnull


    I'm not sure what the status is in terms of the roll-out of those Irizar.Ie trams that Aircoach have for the Dublin Airport Car Park and Staff Shuttles. Some of them were delivered last year on 242-D plates and have barely moved since they were delivered and some of them apparently have batteries that are so flat that they can only be moved with the aid of a mobile generator.

    The last time I was up at the airport a couple of weeks ago as well there didn't seem to be much sign of any infrastructure going in to charge them at the stops either.



  • Registered Users, Registered Users 2, Paid Member Posts: 9,096 ✭✭✭dublinman1990


    Have either the DAA or Aircoach applied for planning permission to Fingal CC for installing new chargers for this new Irizar fleet at Dublin Airport's Car Parks?



  • Registered Users, Registered Users 2 Posts: 962 ✭✭✭d51984


    How many more electric buses are due to enter service? Has the order been fulfilled or is there more to come from wrightbus?

    The single decker electrics (The EA) I think, can someone enlighten me what the hell is going on with these, what a bloody waste to have them parked up for months, if there's a problem, heads should roll.. These could be great for current routes like the N2, Bray locals… 220s.. 104s… the list could go on…

    I know most the routes above are go ahead but surely to god chargers could of been installed in the last year instead of them sitting around gathering dust for nearly a year, replacing single decker diesels on a one for one basis. ]

    These single decker electric buses (some have been delivered over a year ago) are in service day in and day out in Athlone with no problems, so what's the problem with Dublin? I also believe a company in Ardee is making a small fortune storing them….. Only in Ireland.

    Im a fan of bus connects, the NTA, etc etc but by god stupid stuff like this grinds my gears!!!! GET THE BLOODY THINGS IN SERVICE ALREADY!!!!!

    Its a disgrace Joe!

    Electrifying the depots is a tad more complicated - it’s not just charging equipment. The capacity of the power supply on the grid that serves the depots has to be increased too - all of that is taking time. That doesn’t seem to have been fully considered when the buses were ordered first.

    There is work ongoing on electrification at Harristown and it has been since last year (that’s why Jamestown is in situ), and Donnybrook is supposed to start soon.

    I believe that there are modifications now being carried out on the Dublin Bus EA fleet - what exactly they are I don’t know.

    I also believe that there are some differences between the DB & BÉ versions. The DB ones have had issues with software and rolling back down hills while the brakes were applied.

    It’ll be a while before the GAI routes get any as they will likely need additional space elsewhere to house some of the existing fleet if Ballymount is to have chargers fitted.



  • Registered Users, Registered Users 2, Paid Member Posts: 19,032 ✭✭✭✭LXFlyer


    Summary of electric bus orders/deliveries:

    Bus Éireann:

    EA Class - 20 in service; 1 left to enter service (some of these are earmarked for Sligo, but are all being used in Athlone on rotation pending charging facilities being installed in Sligo).

    EWD Class - 58 in service (all in Limerick); 63 on order/to enter service

    Dublin Bus:

    EA Class - 34 to enter/re-enter service (7 had been in service before they were suspended)

    EW Class - 119 in service; 101 on order/to enter service



  • Registered Users, Registered Users 2 Posts: 962 ✭✭✭d51984


    LXflyer, thank you for the detailed explanation. Its just very frustrating to see electric buses lying idle for over a year, hopefully the problems with the EA class can be resolved soon and they can re enter traffic, however on the plus, its great to see nearly 120 electric buses in service in Dublin at present. I honestly did not believe it was this many… good to see.

    Do you know by any chance if the new garage been built in Blanchardstown is to be fitted with EV chargers? It would be a bloody shame if it was not.

    Its a disgrace Joe!



  • Registered Users, Registered Users 2, Paid Member Posts: 19,032 ✭✭✭✭LXFlyer


    Any new depot that is going to be permanent (unlike Jamestown) would have to be fitted out for an electric fleet.



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


    If some of them are moved to Sligo, is Athlone going to have enough buses?

    I am also just realising that the NTA is going to have to buy more single deckers sooner than later if they want to continue the rollout of the various town services. Are they planning to seek more single deckers? Or they are going to make do with what they have for now? My understanding is the EAs (BYD Enviro200EVs) are no longer made anymore so they will have to look for other options?



  • Registered Users, Registered Users 2 Posts: 962 ✭✭✭d51984


    I say there will be some inter depo, maybe inter company transfers with the single decker electrics when they are all sorted, however saying that, I dont think go ahead will get another year max out of some of their streetlites, they are hanging together at this point. They should never of been ordered in the first place, a very poor bus all around.

    Its a disgrace Joe!



  • Registered Users, Registered Users 2 Posts: 962 ✭✭✭d51984


    I would love to se the GB kite electroliner considered if any more orders for single decks are placed. If im in not mistaken ,some parts are shared with its bigger double deck brother which currently operate in Dublin and Limerick.

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


    Well they ordered some Yutong E10 Electric's for local link service, I think only two so far, but perhaps a small scale trial that could lead to more later.

    Wrights have a single decker electroliner.

    ADL have launched a new (ADL Only) ADL Enviro200EV

    And there is the new BYD BD11

    Volvo BZL Single Deck would be a popular one with some around here.

    I'd assume the Irizar ie tram (non bendi model) might be a bit too out there!
