is Mise,
for crying out loud, on one hand you want the most advanced ultra fast rail network & on the other hand you can't envisage how repairs would be done on a monorail ?
Are you totally lacking any sort of vision whatsoever ? How do you think a broken down ultra fast train would be repaired ? Do you really have so little imagination that you can't see a monorail repaired ? Don't you think the engineers who design such machinery don't have ways of fixing it ? You need a smarter argument than that against a monorail.

Hmm, looks like the subjects have lost interest in the subject. How about a quick survey on ultra high speed, high speed or monorail trains to service via the remote parts of Australia.
Just write the name of the type of train, no other arguments of for/against needed. Just an indication what people would like to see being built.
cheers

No, not lost interest, just missed your post.
I think that my previous post answers your concerns.

Just how would a monorail train that had broken down be removed from the track?
Drop it if it's suspended?
Would the monorail wending its way across the vast reaches of Australia have to have a service road built along its entire length and how far apart would the sidings have to be, because using a siding is the only feasible way of removing a straddle train from the main line.

You have never yet stated what you mean by a monorail; do you mean a train running on one rail, or suspended from it, or do you mean the two tracked trains running on a concrete beam with stabilizer/retention wheels?

I am not an advocate of high speed trains, rather I'm an advocate of a ground level two rail system using steam locomotives.

is Mise,
whichever works best with the available technology. The main factor would be that the train would not require embankments, bridges, crossovers & wide clearings of Bush land. The repairs to a broken down monorail present absolutely no technical challenge whatsoever. There can be a technique which lifts a broken down carriage or lokomotive onto a recovery wagon either in front or behind it. That can easily be designed into the train. It is absolutely no point even worth considering from an engineering viewpoint.
On-off ramps for cars & trucks can be placed literally anywhere. No cattle or fallen trees or other debris washed onto tracks. It really is a win-win system.

individual,

What works best with the available technology is two steel rails attached to sleepers, but what I'd like to know is are you talking about monorails, that is one rail or are you talking about straddle beam trains?
Steel wheels on steel rails or rubber tyres on concrete, with all the attendant frictional losses?

As for embankments, they would still be needed as would be culverts/cuttings and tunnels on any long monorail on the East Coast of Australia, then there are the thousands of supporting column on a long line and the infrastructure, such as roads, to get the columns into place, or do you envisage the 'monorail' carrying each segment of its intended track to trackhead and then lowering it into place?

A conventional railway has two contact points, wheels and rails whereas some 'monorails' have five running surfaces on the beam.

Just out of interest how do you think that a suspended crane could lift a broken down suspended train from the track?

'Monorails' don't need to be elevated but can be built at grade thus saving all that concrete in support columns.

Monorails and "monorails" have their place but it's in cities where there is already infrastructure to facilitate their building, such as the newly opened one in Mumbai, India, on which I hope to have a ride next year.

is Mise,
You remind me of that Cowboy some 150 years ago who said that wheels will never take over from the horse.
Now they've been to the moon & back. I'm sure there were people who argued if the control handles of the space craft should be made of plastic or bakelite just like you do now about a single rail or straddle beams.
The technology is there for a monorail it's only resentment of something new or different or even fear that it might work that stands in the way of actually building it.
