Isn't this the same City Council that didn't like UlTra because of visual intrusion?

Monometro is a greatly updated version of the Wuppertal suspended monorail
which has been running for the past 50 years. It's not a "new" idea
but has evolved from
an established and successful (so far as I know) Wuppertal system. There are
many other similar concepts that have been proposed (Sky Train, Sky
Trolly, Sky Tram)
but none have attracted the necessary funding to make progress.
Monometro apparently has overcome this problem and may actually make
it to the demo stage in a year or two. That
would be a significant accomplishment as it would be a rare event. Moreover,
it overcomes the "sole source" problem by using conventional rail components.
How the market will react is yet to be determined. Links to other
similar systems are

Perhaps it has to be a suspended monorail, not a supported one?

It seems that I recall that the Indian Railway Company designed and
built a somewhat similar suspended system that also used standard railway
components. The project was abandoned after a high cross-wind gust slammed
the test car into a support and killed some people on board.

Dan the Blogger has done quite a lot of design work on a switch for a
suspended PRT. Here is a post from 2009 - he has probably done more
on this topic by now:

Thanks for the jpod diagram. Not to be picky but I see a 2 rail system. They are close together, but it's not monorail.

They all depend upon wheels that must quickly come up to speed when they
contact rails and that is always going to be tough on the traction portions
of the wheels involved. It's a lot like airplane tires being forced to
almost instantly coming up to speed when airplanes touch down on runways.
That is the reason that you see those black areas on runways in the areas
where the airplanes touch down. This makes for pretty short life for most
airplanes.
Kirston Henderson
The first thing I would try is a lubricated slider that raplaces this "third wheel", since the contact would only be momentary. Old machinery....planers and shapers, use to use sliders made from wood. I think they used vacuum to extract all the liquids, and then pressurized grease to imperveate the wood. This lasted a very long time.

I vaguely remember that there were gyroscopic issues as well with
pre-spinning aircraft tires.
Such issues probably wouldn't effect a vehicle in a captured guideway.

I can't imagine any car trying to park before it is stopped. In any event, the gyroscopic effect is proportional to the speed of rotation.

Since we are talking small wheels in the case of PRT, why not just spin the guide wheel up to speed with a small electric motor?
