Looks to me like it picks up +ve and -ve on each pantograph. What happens if it wants to change lane for an obstruction or slower moving vehicle? I suspect one pantograph could bridge both supply wires. IIRC trolley buses had two pivoting poles that could accommodate such movement.

Wow, that has to be one of the most laughably clunky systems ever invented.

...they'll be installing rails next to make sure they stay in lane.....

Interesting things, trolleybuses. We had a really good trolleybus system in Huddersfield, which finally stopped in 1968. There were lots of substations to provide the c. 600V DC to the wires, some of them can still be seen.
I don't really know why trams are preferred, I don't doubt there's a good reason. Higher carrying capacity maybe. I'm sure Edinburgh could have wasted less money by using trolleybuses instead!

Same here, you would think that trolleybuses would be much less disruptive in terms of building or changing infrastructure, for starters. OK I would think trams are potentially much more energy efficient (steel on steel versus rubber on tarmac) in theory, but I'm not sure how much difference that make sin the grand scheme of things.

Most of Scandinavia runs on hydro power, it makes sense to try and use it in as many ways as possible. It also means they can sell their polluting gas and oil to us. Shame they are down prevailing wind of us and get the acid rain from their exports.

Limoges has a wide-ranging trolleybus system that has been in operation (along with trams at first) since the early 1900s. Originally it was hydro-electric powered. The city is now regarded as a world authority on the technology (so the buffs tell me). There have been suggestions in recent years to re-introduce trams, but why bother?
Intriguingly, a couple of kilometres from me is a field that looks as though it was once the beginning of a scrapyard. Right at the front of it is (last time I looked) an ex-Limoges trolleybus. Why would anyone tow it that far to dump it?

It could be beings from another planet. They chose to design their pods to blend in but got their siting wrong.
Avez vous noticed these pods trolleybuses in other areas, or strange lights being emitted from your trolleybus pod?

With battery technology advancing, it seems old fashioned for road vehicles to pick up electricity via overhead wire. Such system should be used for railways only.

A little naive surely, we are getting better with battery technology but still way short of powering a city bus for full 18 hour running and fully recharging in between.
I have seen electric buses on park & ride service.
Do you know of a city which is doing electric buses in normal service?

Its not battery technology improving, it's lots and lots of milk float batteries. And the LEZ regulations.

Trolley bus anyone? - bathtub tom
