Why would they not, after all, there is no length restrictions. The only part of concern on the 34 is the turn outside the church at Barnet. I was referring to the efficiency of the type of route but in terms of length restrictions I would add St James Street as it stands there now. I know some LTs have operated on Rail Replacement but they and other vehicles constantly ride the kerb and not sure anyone cares about RR to have bothered to test it round there, so I guess any new bus will need to be tested there too. Nothing more than a keyboard driver comment. No bus is that aerodynamic, some may be better than others, but nothing to stop them getting up to a high speed. You never heard the saying, never judge a book by its cover. Obviously, we are not looking to win F1 races here and I have no doubt it will get up to speed but is all about efficiency and every little helps. It may be better, worse or the same but if I were Arriva I would send one of the 307 ES out on the 34 for a day and see how it does and then send out a BZL (if they had one) and see how it does for a day. That stand at St. James St is a piece of pie. Only coming out from one of them is tight. I could take an LT around there with my eyes closed and not hit the kerb

The Engineering Director knows how they operate, the route does not need a day run to gather data. Just one trip over the whole route with a laptop connected can data log almost everything on how they would perform in service. There has been a few routes checked over with them.

If that refers to first part of post then, no real evidence behind it but from experience using the different types, the BZL feels like it will use a lot of energy to get up to the speeds required for the constant fast section. It looks and feels massive and not aerodynamically that good. The 113 seems to be doing fine which would be a comparison route to 34/SL1 with the Electroliner although in fairness there aren't many BZLs around to know how well it would do. Would you take the risk? You might end up having to need extra spares as mentioned in the Stagecoach thread that the 277 is getting a charging spare and the 58/D7 are kinder on the batteries, so sounds like the route type and/or schedule can have an impact on the ability to the run the route efficiently with electrics. If it refers to second part, Superloop is another 'mode' and it makes sense that it has a unique interior to normal buses. Whether matching the colour of the route i.e. red for SL1 or a standardised colour for all SL routes. Nothing more than a keyboard driver comment. No bus is that aerodynamic, some may be better than others, but nothing to stop them getting up to a high speed. You never heard the saying, never judge a book by its cover. In all fairness, the OP literally starts by saying “no real evidence behind it” so how is it a keyboard driver comment, whatever such a thing even is in the first place.

I hear you 💯, tbh I thought when I saw 268bhp for the BZLs I thought Volvo are having a laugh because that is the same output got the single deck BZLs and infect the single deck BZLs also have a 536bhp option, so why not the double deck? The BYD E400s we have are 408bhp and are 400kgs lighter and they are not that rapid, intact most of them are sluggish. I mean the BYD E200s we have are 240bhp, yet Volvo think it's acceptable for this large heavy vehicle to have 268bhp. Besides I wouldn't call any bus aerodynamically good. All buses employed on TfL work including diesels and hybrids have had their acceleration software limited to 1.2m/s² and have done for some years now. This is to minimise injuries to passengers caused by late running drivers. As such it's a bit pointless having a 400bhp motor if it is limited to about half that in service.

I am completely aware of the limitation behind acceleration but even from 15-30mph some are so sluggish whilst others are quick within the same batch of buses. Some get upto speed quick and others are very sluggish and this is even with new buses. Also all the BCEs are overall useless on hills, some worse than others so all that power/torque doesn't help them. These are the reasons I commented on the overall power of the BZLs.

If the OP says that there is no real evidence behind it, then it makes no sense whatsoever, hence the keyboard driver comment. I cannot see why Volvo would develop a bus that would not be able to go to the 62.5mph limit. They are highly likely to have this and other speed limited options at 55, 50, 44 and 28 mph

ES28 has arrived at TH, due to ES023 going to Norwood to be MOT'ed

Just seen ENS28 outside of TH on a tow truck— not sure if it’s being towed into or away from TH

No one mentioned anything about not hitting 62.5mph either. I still don’t understand what on earth is a keyboard driver is?

Speaking of SL1, I'm predicting theyre gonna use Enviro 400 EV just like the SL3. Why would you think that? It's a Superloop route.

Arriva dont really order E400EVs

Why would you think that? It's a Superloop route. In case you haven't noticed the Superloop routes are operated by a number of different vehicle types. Each operator chooses which type they will use. There is not even a London demonstrator ADL 400EV on the road yet and deliveries are not due to start until next year.

There's something seriously wrong if you need drivers for a keyboard on your PC I think it's the equivalent of an armchair pundit in football
