I don't know if is just me, I've noticed how terrible Tottenham AR Gemini 3 buses have gotten. The buses have flat batteries, and some can't climb up the Hill. Sounds like AR batch Gemini 3s starting to overrev due to the long term flat battery issue causing slow acceleration. A very common issue across all garages, companies and Volvo batches. I believe the WN Gemini 3 batch had gotten new batteries recently alongside their refurbishments. Most 17 reg stuff having this issue now due to being 6/7 years old. For some reason it takes 1-2 years to sort out.

More expensive to buy AND huge midlife running costs due to battery replacement, not to mention the waste. After the second battery cycle that really only limits a very expensive bus to 14 years use. Thats terrible! How do ADL hybrids compare? Are the first of the 2nd generation ADL hybrids (like the 14-regs on the 156, 205 and 345) still on their original batteries?

Arriva should have ordered more diesel buses for their fleet as Hybrid buses from What I can understand is that, after 6/7 the buses becomes unreliable. I thought by getting new batteries for the Gemini 3 doesn't take long. So does it actually takes 1 or 2 years to actually sort the batteries?

That proves that ADL does a better job than Wright Buses, in terms of reliability and performance

TfL had almost entirely stopped specifying straight-diesel double decks buses upon the advent of Euro6, with little more than 100 entering service between 2014 and 2017. It wasn't down to Arriva, as operators order what TfL specify, largely.

I don't know if is just me, I've noticed how terrible Tottenham AR Gemini 3 buses have gotten. The buses have flat batteries, and some can't climb up the Hill. This sounds very similar to a few HVs (specifically 17 reg) at Norwood. I’ve noticed a few (HV285, 297, 312 as well as others) don’t even move up South Norwood Hill at anything higher than 5mph, just revving all the way up in gear 1. These same HVs are quite slow at picking up speed even on flat land— changing gears way to quick, whilst the gear change itself, ironically is very slow…

Funnily enough I was about in Reading today where I rode a ADL Hybrid on the route X4 to Bracknell. I cannot ever see Hybrids or Electrics becoming the norm outside of London due to the reasons you mention.

The whole midlife running cost is a killer for sure and makes me wonder how happy in general London operators are even with busy traffic areas. Probably the main catalyst let alone mediocre/bad fuel savings outside London that they don’t catch on at all. I can’t comment on ADL hybrid battery life, as barring W 15 regs I don’t regularly ride or observe those with stop/start. Transportman91 I say Gemini 3s take an long time to get battery replacements, as I notice 15 regs lasting an good while running purely on diesel for an 7-12 months or even approx 2 years. 🥲 Although could be less months, either way it’s a long wait for whatever reason. Most 17 regs in my area running without stop/start for at least 8 months now.

Tfl gonna realise it too late

Tfl gonna realise it too late Catch 22 though, do you spend an arm and a leg replacing the batteries in the hybrids to get the max life out of them, or replace them early and move them on to a market that doesn’t want them. That’s hardly sustainable either. Sorry but imo batteries to promote sustainability is a completely false economy, I’ve always thought that

Tfl gonna realise it too late ADL boldly state that their new Enviro400EVs have batteries which would last 2 full TfL contracts or at least 10 years in provincial use, they're getting somewhere.

Part of me thinks it is probably down to how intensively used those AR HV's are being used on the road pretty much all hours of the day including the middle of night with AR having 6 night routes meaning good chunk of their HV fleet is actually out on the route at night on their night routes. That said they will finally have their annual rest day from tonight like with all other London buses on Christmas Day

Hi because a particular garage is having issues does not equate to all hybrids and electrics being unreliable

I cannot ever see Hybrids or Electrics becoming the norm outside of London due to the reasons you mention. Are you sure it was hybrid as Reading converted their hybrids to diesels? Hybrids are old hat at this point and never became the norm outside London because the savings were never really their hence why most provincial examples were converted to diesel. Electrics don’t exactly fall into this category - batteries have improved since then and will continue to do so all the time as per any technology
