Are the deckers total electric or virtual electric ... Not aware anyone is planning on produce a totally electric dd yet. Virtual electric reportly run under electric power 85% of the time.

It's been said that London United will be getting four Electric Metrocitys for the H98

An article in the latest Bus and Coach buyer "virtual magazine" about the BYD electric buses mentions that the 4 electric Metrocities due next year will run on the H98 based at Hounslow Garage. It also says that TfL expect to have around a dozen all electric buses in service by the end of 2014. This leaves room for 4 (or so) more on top of the 8 we know about - 2 BYDs, 4 Metrocities, 2 to be confirmed all electric double deckers. Unlike diesel buses can't really scatter them about as you need to install the charging infrastructure at certain locations. Incidently one of these is indirectly the extra bus for new contract on 391, so 391 gets a transferred bus instead I suspect charging will be at Hounslow bus garage (including stand), not sure the Hayes End, Kingsway stand would be fitted as cables in a quiet street might attract the undesirables to vandalise as it is an unsupervised location.

I wonder just how heavy the all electric deckers are going to be.

The article did not distinguish but I expect they will be virtual electric. I think that links back to what has been said in TfL Commissioner Reports over recent months. If I was asked to guess I suspect they may be Alexander Dennis products - whenever they get round to launching their next iteration of double decker. I believe it's long been rumoured that they are aiming to move things on from current hybrids. We shall find out in due course.

Charging will be done at Hounslow. As you say I can't see TfL wanting electrical infrastructure on uncontrolled stands. A garage environment makes much more sense. Reading about the BYDs the desire is to get vehicles that can be charged overnight and then run in service for a traffic day without further charging. This must one of the aspects that TfL and the operators are evaluating. The article quoted BYD as saying they believe the batteries in their buses will not need changing. They estimate they are good enough to last for 11 years based on one daily charge (roughly 4,000 charges over the vehicle life).

I would guess, the electric double decker will have the elements based from the NBFL. If it goes successful, hundred more should be ordered equally to the Hydrogen buses which was originally planned to have 60 hydrogen prototypes but order got cancelled in 2008.

Wouldn't H37 be a better choice for an all electric bus though, as its shorter than the H98? Pick any DLE you want so long as it's not 22.

It is interesting all these different type of eco vehicles coming into play

I wonder if TfL want to try out electric single deckers on a longer route to make sure they're getting a good evaluation of the technology. To date most of the hybrid / hydrogen / electric single deckers have been run on short, intensive stop start services. These give one aspect of in service evaluation. I am not very familiar with the H98 but know it's a busy route (when I've seen it at Hayes & Harlington) so perhaps it will provide a different test of the technology given the longer runs needed and potential for faster runs between stops than is ever achieved on the 507 or 521? If TfL's plan is to move progressively to cleaner technology across London then it needs to have done a wide ranging set of evaluation tests so it is confident about specifying the right vehicles for the right routes and so operators have access to the evaluation data to help them choose future vehicle types.

I suspect the H37 stands aren't the easiest to add a charging point to. They are also unserved by any other route so any equipment added couldn't be used for another route. I don't think a pure electric (instead of virtual electric) double decker will be seen soon, most are fairly critical for the 18 tonnes limit and batteries are heavy (even without the engine), lightweight batteries are very expensive. its likely to be trade off between reduced batteries (reduced range) or needing a tri-axle Off-topic (but part above is about electric Optare MetroCity) the Optare website under regulatory news has a half year update and suggests the Optare double decker will be launched Q1 2014

I saw EB1 out and about on Thursday, I don't know what happened as I saw it at Lambeth Bridge around 10.50 heading to Waterloo and it was back in the garage at 11.10, but back out again just after 12.00 for one last round trip with LVF showing it finishing at 13.12. I don't know whether it popped back for a bit of juice, or something else. Nice to see it though as it does look very different. Just need to get a ride now.

Stagecoach London will take in vehicles powered by any means if LBSL pay us to do so. I have an opinion on this but it is too early to declare it, and not what you would expect. We have 1 new diesel on order and I expect us to (possibly) place orders for a further 12 before Easter so, yes, diesel buses will still be ordered. WH and RM will receive E400 diesels currently allocated to route 53. I suspect emissions will become a factor, only yesterday Evening Standard was saying how 2 heavy bus areas, Oxford Street and Putney High Street have already breached the NOx limit in 2014. I can see virtual electric (or full electric) soon. By coincidence Milton Keynes this week went full electric on a route with induction recharging at bus stands each end, so rolling out the technology must be close. My own hunch is that as I-bus uses some form of GPS location, it will soon be linked to the drive to get buses with parallel electric drive to shut down diesels in pollution hotspots and work on batteries in these areas. Effectively I'm sort of forecasting a return to trolleybuses (but without the overhead wires) in the congested areas. Diesels will still be ordered for more rural parts.

Hounslow is expected to take delivery of 4 full electric Optare MetroCity's for use on the H98 route late Feb early March (date TBC).
Two DLE's will be displaced from AV to pastures new.
The garage will have overnight charge points fitted in the garage, with a fast charge point on the garage forecourt where the EV's will be used into rotation.
The trial Solo EV deliver three rounders on a signal charge with spare battery capacity, however, no passengers were carried but the vehicle was tested under maximum battery drain conditions (the driver was sweating with the heating and blowers on full all day!).
The MetroCity is larger that the Solo so will be interesting to see how the charge measures up....
