@ajsadauskas@poVoq is there not something, however worthwhile, to the flexibility of being able to construct single routes that can freely utilise track and road?
Whenever mention is made of simply using interchanges, between either lines or vehicle types, I always feel the friction of having to do so for passengers is not considered.
Meanwhile, adapting routes to where people need to go seems awesome, and boarding a route that takes you directly to your destination too.
My question was more around if you want a single seat journey that runs as a bus down local streets, then follows a track, why not build a guided busway, like the O-Bahn?
Instead of the extra mechanical complexity that comes with fitting the wheels-to-rails conversion mechanism, you just need to attach a couple of guide wheels to the bus’ steering mechanism.
If @AussieWirraway is around, he can explain more about how it works. But it seems to me, in most cases, a buided busway is a better option than a bus-train.
@ajsadauskas@aus.social@ajsadauskas@lemmy.ml@poVoq@AussieWirraway yea I’d imagine the answer is technical and beyond me. The only thing that comes to mind is whether you’d still want to use track only vehicles for their intrinsic advantages, and if so, whether the o-Bahn “road vehicle on tracks” is worth it.
On the o-Bahn, I’m curious why that couldn’t just be a dedicated road for buses? I suppose freeing the driver from steering is a good thing?
It also has many of the benefits of the train-bus, in that it operates like a rail service for most of its route.
Yet it also runs along city streets through the Adelaide CBD (avoiding the need for a costly tunnel), and as a regular bus service through the suburbs of Adelaide.
It is also used by routes going to multiple destinations in the suburbs.
Thanks! I appreciated the safety section … seems quite good!
As a Melbournian, I’ve always been kinda against the love affair the city seems to have with Trams. Largely because of their lack of flexibility and the way they essentially pollute streets with overhead power lines. Buses are the obvious alternative to Trams for inner city PT, so it pleases me to see this.
In Newcastle, the trams are powered by a battery. They charge by raising a pantograph up to touch a steel bar at each tram stop: https://youtu.be/yFQRo3I15fY
In Sydney, along George St and Circular Quay, the trams are powered by a third track embedded in the roadway. So, again, no overhead wires in this part of the network: https://youtu.be/DdiZ3UTa4g4
So yes, trams without overhead wires can be done.
Even if Melbourne didn’t move to a different power system, the city could reduce the amount of overhead wires by:
a) Giving trams their own right of way in the middle of the road (rather than sharing their lanes with cars), and
b) Hanging overhead wires from poles in the middle of the road (as happens currently on Burwood Hwy) rather than from poles on the side of the road.
Dedicated lanes would also make a world of difference in terms of travel times, frequency, and preventing trams from bunching up.

@maegul @ajsadauskas@lemmy.ml @poVoq @AussieWirraway Less room for driver error, which means better safety and higher speeds. Also, the concrete guideways provide a smoother ride than gravel.

@maegul @ajsadauskas@lemmy.ml @poVoq @AussieWirraway Here’s a video from when the O-Bahn was first launched, which explains the concept and it’s rationale better.

@maegul @ajsadauskas@lemmy.ml @poVoq @AussieWirraway It is possible to do trams without all the overhead wires.
