Re: Tunnel under the airport ASAP!

Too bad you didn't measure the depth! Neither did you. It looks deep enough from Google Streetview. drain.png Even if it needs to be lowered, that's still much cheaper than buying up neighbouring properties or building a tunnel. I suggest you delete the new thread. You seem like a nice person to be...

Re: Tunnel under the airport ASAP!

New plan to make it even cheaper! It's in this new thread. https://www.sensational-adelaide.com/forum/viewtopic.php?f=17&t=7194 1NEEDS2POST, It's a lot smaller than you seem to think it is! Two O-Bahn tracks plus clearances comes out to 6 m wide. I've measured the width of the drain on Google Earth....

Cheap Airport O-Bahn

Adelaide doesn't have a dedicated public transport corridor from the airport to the city. Fortunately, there is a corridor used for a drain that goes between the airport and Mile End. This drain can fit a cheap O-Bahn that takes buses from the city to the airport, bypassing all of the traffic. Keswi...

[U/C] Re: M2 North-South Motorway

Years ago, there were plans for a southern suburbs O-Bahn. Well, this motorway is just as good! :banana: What are the plans for bus routes to use the motorway? This could drastically speed up bus routes from the southern suburbs, such as Aberfoyle Park and Morphett Vale. At the moment, those bus rou...

Re: Tunnel under the airport ASAP!

Another totally different idea: instead of a tunnel, we could have a lowered O-Bahn along Keswick Creek. An O-bahn that floods every time it rains??? Yes :wink: It rarely fills up and when we do get heavy rain, just don't use the O-Bahn track, send the buses along Sir Donald Bradman Drive. That's w...

[U/C] Re: M2 North-South Motorway

How is the setup at Emerson going to work, given that the support pylons of the current overpass are in the way of the tunnel, unless the tunnels deviate to the left or right of the structure? Also it rules out any railway underpass or overpass, so that's just bungling any chance of a grade seperat...

[U/C] Re: WEST (Football Park) | Developments & News

West Lakes Boulevard was built in the 70's with the intention of a train line going down the middle.....yes a heavy rail line (extension of the Hendon branch) However the property developer objected at the time saying "that sort of development would bring the wrong sort of people to West Lakes" So ...

Re: News & Discussion: O-Bahn

Trolley buses are used in so many locations in the world it is impossible to believe we could not build them here. The tech is old, cheap and reliable. Yes, but not many places are building more trolleybus routes. Meanwhile, lots of places are buying battery electric buses. For example, Wellington ...

Re: News & Discussion: O-Bahn

I suspect that there would be very few routes that are worth stringing wires for the entire length, so a battery of some kind would be needed. The size would be a function of how quickly it can receive top-up charges at a few powered stops or running under (over) wires in the city. Maybe the big fl...

Re: News & Discussion: O-Bahn

Buses in the middle is a good idea (and matches trams) but does mean that pedestrians from either side have to cross through the car lanes to get to it. Although that's not really a problem if those personal vehicle lanes were akin to Pirie Street with multiple crossings. One big advantage of the b...

Re: News & Discussion: O-Bahn

The O-Bahn tunnel was quite cheap at $160 million. The thing is, there are no bus stops inside the tunnel. When you put bus stops in a tunnel, the cost shoots up because the tunnel will be wider where the stops are, plus you need ramps for the pedestrians. It's looking at the problem the wrong way. ...

Re: News & Discussion: Electricity Infrastructure

Who will use the hydrogen? It would be a good idea to set up an ammonia plant nearby to take advantage of the cheap hydrogen. At the moment, ammonia for fertilisers and explosives is the largest user of hydrogen.
