My city has been stuck trying to expand its tram system for decades at this point, but whenever I mention that we could introduc trolley buses instead people look at me like I’m crazy!
They just make so much sense for our use case. We’re a hilly city, so the rubber tyres are more suitable than steel on steel, the routes they want to build on don’t really have the space for separated infrastructure, so having buses that can run on the roads will be less disruptive, and by not having to install rails they’re a lot cheaper too.
