I'm Czech and my city has a trolleybus network. Every single trolleybus has either a) diesel engine or b) battery backup, depends on their age. Hell, there are even entire lines where 1/3rd they run on batteries. But, they can be smaller, so the vehicle is lighter.
that still doesn't adress the cost of implementing it on the more than 300 bus routes there are in Santiago or how probable is that the infrastructure would get damaged or destroyed every time there are protests.
Fortunately riots aren't an issue in my city
yeah, but how many routes?
9 trolleybus lines, 3 of which I know have about 1/3rd without trolley wires at the end so buses go on battery/diesel
Santiago has 300 hundred lines of bus. all of them potentially serviceable by EBs.
Even if we electrified the main corridors, we would still need a lot of buses able to run the entire length of the rout independently.
and Santiago being Santiago that kind of infrastructure would be damaged on riots or something.
Okay? Doesn't mean Trolleybuses aren't the best compromise. Infrastructure costs money, so lets make the same argument about roads shall we?
we have private hways so the state doesn't have to pay as much.
We aren't a rich country.
Then privatize your local public transport. That is how it works in many of my country's cities. Networks are usually only half owned by the city government
is half privatized already, but is heavily subsidized.
This number, 300, doesn't say anything. How many miles is that, excluding duplications? The inner city is easy and cheap to cover in power lines for trolleys to replace busses here, and everything other may be best kept on diesel.
What protests, lol? Repairing power lines is easy and fast and I doubt someone would target them.
My city only really has trolleybus lines in the city center where it is cheaper and means no localized pollution
Mine – too. It's just rational to do that for most popular and short routes.
its not that costly tonimplement. Why do you think they were implemented back then, instead of running everything on diesel engines?
The upfrontninvestment might be higher, but the running costs are lower, since the electricity is far mor energy efficient and electric engines need way less maintenance than IC-engines.
non contiguous catenary is the best solution imo
The what? I'm not Bri*ish enough to understand that
