The biggest problem right now for the O-Bahn is that the traffic lights in the city do not sense buses. It's a shame that the O-Bahn tunnel gets built, all for the buses to wait for a minute at the traffic lights at the entrance to Grenfell Street.
The tunnel should have never been built. That money could've been spent converting it to light rail and joining the track down North Terrace. Anyhow, it is there now and the tunnel should go all the way to West Terrace and beyond as explained in a previous post.
The O-Bahn needs to be expanded, not replaced. An O-Bahn track over Keswick Creek from the airport to James Congdon Drive would be great. Adelaide Airport would be incredibly easy to access from the city and few cities in the world would have a shorter trip from the CBD to the airport.
No need for a track just cover the creek and run normal buses if you prefer it to light rail. Remember that the creek in some places is narrow and only one carriage way (or track) will fit.

Ttp interchange has no room currently with most passengers not interchanging at ttp, they just ride on through on the bus they are already on.
When I have used the TTP interchange 50% of passengers left the bus at the interchange.
Plenty of room to build the light rail line in a trench with the bus interchange above it.
Due to the large amount of passengers this station would be transferring from bus to train it would need lots of thought to make it efficient and safe. It will need a mass of stairs, escalators and lifts to get many thousands of people an hour between platforms. Like I said TTP alone will need to be bigger than Adelaide Railway Station.
Bondi Junction train station in Sydney is one fifth the size of the Adelaide train station yet probably has a higher patronage.....multi-levels, escalators, different arrival areas and pick up areas....its not transport rocket science.....been done a million times elsewhere in the world.

What about a system like the London DLR, instead of trams

London DLR is light Metro using a third rail for power source....it is also totally grade separated.

You can't have a third "live" rail in city streets.

Instead of converting it, they should build a tram/light rail network across the metropolitan area.

They should improve the obahn. Who knows maybe one day it'll be some weird niche tourist attraction lol.

It really is a shame that the Sydney monorail was stuffed up, because if it had provided a quality example to the rest of the country some kind of elevated system (be it Monorail, Tram, Light Rail) would be perfect for elevated tracks in our wide streets.

Yes you can! https://en.wikipedia.org/wiki/Ground-level_power_supply Here's an example of it in Sydney:

If we want to go electric, it's much cheaper to just go with battery electric buses.

That is not a "live" third rail......it is dead until the tram passes overhead.
That person would be electrocuted if it was a traditional live third rail.
This technology is proprietary ie you must buy all future tram replacements from the original company and the cost is more than traditional catenary.

Or just have overhead wires with a dedicated grade separated track on the O-Bahn corridor, with rolling stock that can reach higher speeds. The Siemans S70 can reach 100kph
