individual,

No one fears them being built, they have been built all around the world, but they are only short lines and I don't think that you either appreciate the enormous cost of building very long monorail lines orthe engineering problems involved.
A road for the entire length of the line is the only feasible way of getting the track and its supports on site, unless the monorail is built at grade and then the few advantages of it being elevated disappear.

You still haven't said what you mean by the term monorail.

monorail
noun
a railway in which the track consists of a single rail,
Is Mise,
That's what I mean by monorail, not parallel. It simply could not work out as difficult as you're trying to make out. I concede that it probably isn't an ideal investors' or rather speculators' proposal but it is a very practical solution from every aspect. Better than what we presently have. A monorail could go through country that would prohibit even a dirt track. The EPA would not have a leg to stand on unlike with a conventional rail or a road.

individual,

"A monorail could go through country that would prohibit even a dirt track. The EPA would not have a leg to stand on unlike with a conventional rail or a road."

Glad that you have finally reached the conclusion that a monorail runs on one rail, now top of the rail or suspended?

To build any monorail you first have to build a road to get the piers and girders in, to get the cranes in to lift the components, the diggers in to dig the holes for the foundations for the piers.

Of course the components could be airlifted by helicopters and men with picks and shovels could dig the foundations and the choppers could bring in the reinforcing steel and the cement.

Probably be a bit costly though!!

This will give some idea of some of the complexities of monorail (straddle beam) construction in a hilly area.

"The monorail vehicles with strong climbing capabilities and have heavy rail capacity, which can transport 30,000 passengers per hour per direction, invaluable in the densely populated but hilly city. Line 2 is for the most part elevated above streets, although a 2.2 km section is underground, including three of its 18 stations in the Jeifangbei CBD and Daping downtown areas in hyper-dense populated area of Yuzhong District. In 2010, Line 2 served 45 million passengers.[3]"

Note the use of tunnels and the viable passenger numbers.

If you have any doubt about what I was saying about a fast enough
train service if trackwork upgraded to UK standards, here is a video of
the East Coast mainline from London to Edinburgh.

We could afford this, especially as airline costs are esculating so fast.
I got a price yesterday Sydney to Melbourne for 2 $1144 !

If you look at the video, the dark blue trains with the white stripe
are the 125s and are the same trains as the NSW XPTs, if the track was
upgraded we would not even have to purchase new rolling stock.
