Yes they can as they store power in batteries, the Auckland ones are capable of this but the distance is not that great.

Only in the city, the rest of the new extension has overheadHeardy_101 wrote:Because if you're going to go to that length then may as well have a tram instead.
As much as it pains me to say this because I love the tangle of the overhead wires, but with modern technology we are steadily moving away from a need to have overhead. Sydney's new tram extension is an example of that.
Actually this is changing rapidly and they can move quite significant lengths off-wire. For example, there is a trial route in Prague where the buses are only running about 10% of the route on wire. These are basically dynamically-charged electric buses that recharge on the move on short sections of wire plus a section of overhead at the terminus and overnight charging.The Inspector wrote:Skexis wrote:Trolley buses are not much use as they can't go anywhere that isn't wired.

But they can charge while on the move, while a diesel or gas bus can go further on each tank but only be refueled while stationary and only in depots.The Inspector wrote:Yes they can as they store power in batteries, the Auckland ones are capable of this but the distance is not that great.
Even in the city, it is still electrified, with ground level power supply. This is a type of ground level power supply that only works for trams, not for buses.The Inspector wrote: Only in the city, the rest of the new extension has overhead
Trolleybuses ARE fully electric buses! Furthermore they drew their power in Wellington mainly from renewable geothermal energy, not from the environmentally detrimental process of manufacturing and ultimate disposal of batteries. Wellington is simply an cynical exercise in political and industry dishonesty.1whoknows wrote:And Wellington no longer has trolleybuses but is buying new fully electric buses - so that worked well didn't it?
"Fully-electric vehicles". What weasel words - they were already fully-electric vehicles ffs! Well, this was predictable.moa999 wrote:An interesting update on Wellington trolleybus.
They've now got one trial bus fully converted to battery.

nope.Myrtone wrote:Okay, there hasn't been any activity for a while. The fact is that Adelaide's tramway network has overhead wires throughout and has recently been expanded, presumably with more lines projected, all electrified throughout. But yet there are no plans for the return of trolleybuses, is this seen by others here as a double standard?
Yes I saw that. Somehow I can't see that getting off the ground. Here's a stylised representation of in-motion charging which is the way the technology is heading:boronia wrote:Maybe this will solve the battery problem for buses? TonyP would approve of this one:

Then put trolley poles on the trailer to recharge the batteries.
