    The best electric busses have electric lines overhead, so you don’t need big batteries.

    Boston had newish hybrid deisel trolleys until 2023, when they replaced with battery electric buses.

    They claimed the catenary was too expensive to maintain, especially with roadwork. Meanwhile the battery electric buses are completely self-contained, independent, and there are multiple manufacturers.

    I’m sure it didn’t help that they were over complicated. This was a new transit line where everyone wanted a subway, but it was too complicated. They needed more capacity than a bus, able to maneuver tight corners, electric to go through tunnels, and unconstrained in traffic. They created Frankenstein monster and called it “bus rapid transit”. Partly dedicated roadway, partly in traffic. Partly above ground, partly below ground. Partly deisel, partly trolley. Bigger than buses but articulated to fit through narrow streets

    My city is also playing with electric buses buying different brand and models. One Chinese brand they have drives me crazy because it rings a bell as it moves. It’s louder and more annoying than the gas buses.

    I wish my city was running the electric buses at night. Without the noise of other traffic to help mask it, the gas ones sound like explosions as they drive by at 3a. Unfortunately the bus company said it’s cheaper to charge them at night when electricity costs the least.

    jelly… nothing like biking on the wall lane next to the the highway and getting smogged by a gas bus’ top exhaust right in your face, right after overexerting to get up there in the first place

    Edinburgh rolled them out somewhere in 2017 i think? Most of the buses are still diesel powered

    I am for electrification but I just can’t get behind electric buses.

    My city made some study last year and the best way forward in terms of public transport is expansion of trolley bus network. With batteries and constant use it just doesn’t make much economic sense. If you can build the wiring it is much better in long run. You don’t have to have 100% coverage, 70+% is enough for partial battery powered trolley bus, then it starts to be economically feasible in the operating cost sense.

    Also they will need to build some kind of metro system - probably as an extension of commuter trains.

      I was excited when we started getting electric buses here, then I learnt we used to have trolley buses until the mid 70s. At least we got a tram line in 2021 so that’s great

      Isn’t a trolley bus just an electric bus with a “antenna” on top to charge its battery from an overhead cable?

        BEV busses need much larger batteries, while trolley busses can get away with a very small battery

        Keeping that in mind: would a good solution not be to have electric busses with batteries, which also have the umbilicle on a spring loaded or electronically actuated system to raise it to connect to the wires? This would allow said wires which would normally connect a trolley system to be placed along main strips while still allowed busses to travel along lesser used streets. The mobility of busses with the power system of trolleys to ensure they don’t have to stop to recharge or refuel, they can just connect on the main strip and keep their battery banks full.

        I’d even say with something like this a supercapacitor bank to quickly charge those to 100% on connection then allow those to charge the batteries. This would help to reduce charge cycles on the battery and help to keep the batteries in a constant charge or constant discharge state instead of having every bump in the road disconnect the batteries from the grid.

          Trains. Believe it or not. Boston still uses deisel commuter trains, including one “deisel under the wire” on the electrified Amtrak line. Everyone has been pushing to electrify but it’s expensive. Their solution is battery trains. They can run them on battery now, while tAking power from catenary as it’s built. Seems like a huge waste of money, but I guess you have to transition somehow

      Yeah… We kinda solved this problem in the late 1800’s. Overhead electric or powered third rail (depending on need) is really peak public transportation when it comes to cost and efficiency over time.

      People always harp on the infrastructure cost when it comes to rail, but turn a complete blind eye on extreme cost of things like road maintenance and need for lane widening caused by everyone driving huge ass half filled busses everywhere.

      Road maintenance is one of the largest expenses for most states in the US, and it’s largely so much worse than other countries because our dependency on the trucking industry. We’re all basically constantly subsidizing the trucking industry at great cost instead of funding adequate public rail.

        Toronto has overhead electric trolleys. They got rid of the buses, but only because GM refused to make them. The fleet of overhead electric buses were 50 years old, they never broke.

        But I get the appeal of the ebus it just sounds cheaper. One city I won’t name started to build trolley bus network again after they got rid of it in 70’s (because of metro construction and expansion of trams), but they just doing it bit idiotically by wanting to have like 30% of it on wires and rest run on batteries.

        Why? Because the infrastructure is just more expensive upfront.

        Will it work? Nobody knows, people that are building it lobby to get it up to at least 50/50 then it is maybe just feasible.

        I think that roads and buses have place in the transportation but you just need more options not just that.

    My city also has been rolling out electric buses the last few years and they ride so much like their gas counterpart that I wouldn’t be able to tell which is which without the design/colour scheme they chose to tell you which is which.

      We have nearly all electric buses here in Oslo now, and whenever I wind up on a diesel bus I think I’m going to get hearing damage

      Electric buses are far from silent, but WOW the amount of noise and stink we’ve just been tolerating with fossil fuels is insane. Even absent climate change, that’d be worth switching to electric vehicles.

        I almost fucking asphixiated on a diesel bus yesterday because for some reason we had to stop for 5 minutes in the centre of the city and since it was quite cold the exhaust stayed low and just crept into the bus. Fucking traffic.

      What is the source of energy to produce the hydrogen? The carbon footprint of hydrogen is pretty bad unless you have abundent renewable energy.

          Well Germany has to sell their shitty lignite coal to somebody… It’s not like their environmental laws will allow them to burn it in Germany. But Poland is fine…no one cares about the polish greenhouse gasses. That’s Poland’s problem…right?

    Nice, i really love electric bus, it doesn’t stink and it’s quiet. My city rolled out some half decade ago, but it doesn’t last as the company that made it(Chinese) doesn’t support it anymore. Then we got another batch like last year i think. Hopefully this one last.

      They always put a promo sticker when introducing new buses into the fleet.
