Monorail systems have been proposed for three cities viz. Islamabad, Lagos and Cairo. These monorails if built, will help to reduce traffic congestion making the commute easy for people. The proposed monorail systems tend to connect the respective cities with satellite towns as well.

New Kind of Monorail

The main problem with monorails is the track's size, if it's too big, it blocks the sunlight and that decreases the value of the street below, not to mention that if it has too many support columns it can block traffic and create even more congestion problems.

http://emonorail.com

The solution to all of this is a hanging monorail with a very narrow track that is supported from a suspension bridge-like structure, that way the columns are very far away from each other and the track is narrow enough that it can let sunlight unto the street:







and not because is new and modern means it has to be ugly! this new monorails can be as beautiful as the buildings around, even in cities like Paris, Budapest, and so many others!

In all honesty, that's probably more intrusive.

Furthermore, the vehicles are too small, and the decoration is garishly overwrought, especially for Paris.

In Japan, we have a hanging (the only one in the country) monorail in Chiba



here is an older version


It generally looks very clean and allows for more sunlight and skyline

but there are some parts that look ugly like



But this is due to that area having other lines coming in and requiring the monorail to go higher.

I've ridden it twice. I don't know if it was off hours or whatever, but it was pretty empty.
Wikipedia says it has 45,000 daily passengers, 18 stations

I've used it (2010), and my wife has too (2015). Was fairly busy for both of us - even had a video of the journey from Chiba station to Chiba Minato. Excuse her shaky camera though, she wasn't used to using it...





Also, it's not the only type of hanging monorail in Japan - the Shonan monorail is too. We've been on that one as well but again I've only got footage of my wife's shakycam!

The same concept of Aerobus, a Swiss patent from from the 60s which has experienced little success since then: only few temporary applications and some attempts for a real line that never went beyond the planning stage.

Anyhow, this system can't do anything but - as if - mitigate elevated structures being visually imposing and obtrusive, which is the main reason because this kind of solution, albeit common at the mass transit dawn, is now pretty rare compared to the underground one.
Likewise, I highly doubt monorails in particular, despite being an hype recently and having a sort of renaissance in some countries, will ever be able to escape from their niche role in global transit market, no matter what kind of technical/aesthetic scheme it'll be implemented for them.

For China, the main problem is the higher power consumption (~25% more) which accounts for ~25% of the running costs.

That was just an example... the main page for this system is

http://emonorail.com

the sistem itself looks like several suspension structures intercrossing in the middle



In this rendering only two cars were used to 3 or 4 can be easily added!



Furthermore, is not more intrusive but less, the towers are places every block or two, as opposed to 4 or 5 per block as in EVERY other monorail system in the world, suspension structures allow for large spans!

The aerobus runs on a rope and is not rigid, in this system the trains run on a beam, which is rigid! that gives far more safety, and as far as being visually obtrusive, because they are hanging monorails, there is no need for a big track, and that makes it less obtrusive. Because its based on suspension structures, the towers can be placed one every block, as opposed to 4 or 5 every block in EVERY other monorail system in operation in the world... Suspension structures allow for long spans

The scale of the pillars and the suspension wires still make it an eyesore. It's less the pillars and more the beam itself that counts for intrusiveness in many cases. Pillars can be mitigated with things like artwork or ivy, beams can't.

I would also seriously question the idea of having a large-capacity monorail with such a small beam. There's a reason why you see large beams in the Japanese examples-the only small-beam monorail is the Ueno Park line, which is a small tourist attraction, not a mass-transit operation.

Better than any monorails!

The cables are not that big, how could they be so big that they block the sky? the only thing big enough is the beam and that can be easily be designed as a truss to allow a lot of sunlight to reach the street, in comparison, is about 10 times smaller that the current straddling monorails in Kuala Lumpur and Japan...

It might not be perfect, but when it comes to solving traffic at a low cost, this might be the best solution, the amount of material is minimal and the number of towers is also small, please don't throw away any new ideas just because they're not perfect.

I think all those wires and poles are far more unsightly than just a standard monorail track.

LOL at the renderings of the rolling stock- MBTA Kinki Sharyo Type 7 LRVs with the bogies chopped off and monorail gear grafted to the roof.

It's absolutely not a new idea : Built more than forty years ago,

Used in just one city, during a short period. Ask why no more, no in others places ?
It don't suceed to solve traffic problems, it was no low cost, and finally it was not a good idea

Public transport is serious thing, not playing with 3D drawing

Wow. A youtube video of a glitzed-up SAFEGE system.

Never mind that this would take away traffic lanes at lower capacity and higher cost than conventional LRT. Its GLITZY!!

It's only an idea and it's not perfect? .

This one is in use and it looked much better than that imperfect idea.

China unveils first permanent magnet straddle-type monorail train

The first permanent magnet straddle-type monorail train independently developed by China has rolled off the production line in Qingdao. The train runs on two newly-developed systems and uses 10 percent less energy than existing models.

That systems has had quite a few problems. It pulls the cars along with a cable attached to a fixed motor. Unfortunately, the cable keeps breaking.

That's too bad.

I think it's the longest and fastest in operation (https://www.dcc.at/references/oaklan...ort-connector/).
