Montreal's Metro, like Paris' are rubber wheeled and are much quieter than standard heavy rail.

Vegas monorail uses the same incredibly out-of-date trains as those on the ORIGINAL Disneyland?! Not good...

Yup, It feels like your driving over speed bumps in a car. I believe it is from the things that join the actual track together.

That's the nature of a monorail. The old Seattle monorail does the same thing, it would bounce on the gap between 2 beams supported on a pillar.

So what if it was steel wheel? What if the beam had a rail (or maybe two) embedded in the top of the beam, and instead of pneumatic tires, the monorail ran on steel wheels? Would that make a difference to your perceptions?

By the way, the monorail vehicles are different than the original Alwegs from Disneyland. The WDW models were introiduced in the early 90's. As far as how advanced goes, let's face it, there's not a ton of complexity there to begin with. I guess it would amount to a simmilar estimation of how much more advanced are the busses of today versus those of 1960?

The Las Vegas monorail features an emergency walkway between the guideway beams. The walkway can be seen in the follwing picture:



This same feature is required for the monorail planned for Seattle. The walkway can be seen between the guideway beams in the rendering below:



The Hitachi website shows the train-to-train emergency evacuation method that would be used if no walkway were present:

Trains on adjacent guideway beams:



Trains on the same guideway beam:



Train-to-Train emergency evacuation between trains on the same guideway beam requires both a through passage between cars and doors on the ends of the trains. Among Alweg (straddle beam) type monorails, only Hitachi trains feature both.

For more information, see the following websites:

ya, the guideway catwalk didn't exist on older monorail lines before 1965, I think. I'm not sure if the old Japanese monorail built in 1964 has the catwalk thing, (just in case).

The old seattle monorail doesn't have the catwalk, there was a fire on one of the monorail last year and they had to transfer to the monorail next to it, but due to the smoke, some people had to be saved by the firemen with ladders going to the train. All people were saved, no one died and it was a relief. It's the first fire since the monorail first opened in 1962.

this statment was made a few days back...........


To look attractive, they have to be a single track monorails, double tracks when in a dense urban area just block out far too much light and sky from city scapes. The problem with single track is that they are either only going in one direction, or even less capacity by sharing tracks.


The alternitive in a situation where elevated tracks will be required is much more complicated and has alarger visual impact.

AS far as evacuation goes, ideally they will do everything they can to get the monorail back to a safer location or a station.

In a dire emergency, when there really is no other option and they can't wait for emergency personell to respond with a ladder truck or like, there is the option (for those vehicles equipmed) to exit right out the front of the vehicle along the beam. Obviously not something you would want to do, but given no other alternatives. The beamway on most monorails is 2.5' to 3' wide. Again, that would be used only as a very last resort.

I have also seen proposals about equiping monorails with evacuation slides like aircraft have.

Don't dual direction monorails block as much sun as LRT that are elevated or elevated metro systems?

No.

The following figures are from the Hitachi website:

Elevated Conventional Rail:


Monorail:


The following are some key dimensions for the Central Link light rail system and proposed monorail in Seattle:

Parameter: Light Rail Viaduct / Dual Monorail Guideway
Guideway Width: 26' 6" (8.05m) / 2x31.5" (2x0.80m)
Typical Column Spacing: 100' - 120' (30.5m - 36.6m) / 100' - 120' (30.5m - 36.6m)
Typical Column Width: 5' 9" - 6' 3" (1.75m - 1.91m) / 4' 0" - 4' 9" (1.22m - 1.45m)

There would be some additional shading from the emergency walkway of the monorail; however, this is likely to be minor as the walkway will have a grating rather than a solid deck.

Typically most people's experiences with Monorails come from various outdated themepark experiences. Personally I've not ridden on a monorail that compares with a metro rail system, but plenty that more than compare with any light rail system I've ridden in.

:o But some monorails are truely shocking. The monorail on Sentosa Island in Singapore comes to mind.

I came to that conclusion because I've ridden in quite a number of rubber-wheeled trains before notably:

- KL Monorail
- Sentosa Monorail, Singapore
- Sunway City Monorail, Malaysia
- Sydney Monorail
- Walt Disney World Monorail, Florida
- Genting Highlands Monorail, Malaysia
- KLIA Aerotrain
- Changi's Aerotrain
- Bukit Panjang LRT, Singapore
- Orlando International Airport Aerotrain

Most of the rubber-wheeled trains I've been on before are less than 10 years old so they are not antiquated. Based on my quite comprehensive list of rubber-wheeled trains, I would say that it is indeed bumpier if compared to standard steel-wheeled trains. I wouldn't wanna list don all the steel wheeled ones because I've ridden quite a lot of such systems around

The graphics by Hitachi posted by Greg_Christine is very true. Kuala Lumpur had two LRT systems that are elevated and also a dual tracked monorail (and all these systems are kinda near to each other), so it is evidently clear that the shadow cast are very minimal for monorail.

MONORAIL - The Official Thread

Scomi Engineering aims big with Sutra
Tuesday November 27, 2007
TheStar




Having a closer look at the homegrown monorail called Sutra. Scomi Group
Bhd CEO Shah Hakim Zain (right), Deputy Prime Minister Datuk Seri Mohd
Najib Tun Razak (centre) and Scomi chairman Tan Sri Asmat Kamaluddin after
the unveiling at Matrade Exhibition & Convention Centre,KL.


KUALA LUMPUR: Scomi Engineering Bhd is participating in bids and proposals in countries like India, Saudi Arabia, Thailand, Vietnam, Bangladesh, Pakistan, Syria, Egypt and South Korea, as well as Malaysia to offer its next generation monorail called Scomi Urban Transit Rail Application (Sutra).

Scomi Engineering, which is part of the Scomi Group Bhd, is involved in energy and logistics engineering.

The tendered projects were worth RM6bil, said group chief executive officer Shah Hakim Zain after the launch of Sutra yesterday.

However, it was uncertain when the company would be able to secure its first order for Sutra as “the decision to purchase a monorail is a big decision for any government or city,” he said.

In Vietnam, the group has been given six months to conduct a detailed study with the railway department in Hanoi for a monorail project in the city.

Shah Hakim noted that there had been “huge interest” in monorail among Asian countries in the past eight to 12 months due to rapid urbanisation and high fuel cost.

“Many don't realise that a six-car train can take away 17 buses from the road,” he said, adding that monorail could ease traffic congestion and pollution.

Locally, Scomi Engineering had submitted a bid for the Penang monorail project. “There are four bidders for the Penang monorail, so we have 25% chance,” Shah Hakim said, adding that the monorail could cost US$20mil to US$30mil per km.

Johor and Malacca were also suitable for monorail due to the population density while Kuala Lumpur could see extension from the current system, he said.

However, Scomi Engineering had not submitted any plans to the Government for the extension in Kuala Lumpur, Shah Hakim said.

“The Government is planning to take over the KL monorail and will decide what to do afterwards. Utilisation is very high for the KL monorail,” he added.

Sutra complies with 50 international standards comprising safety, quality assurance, vehicle certification, reliability, availability and maintainability.

Its enhanced features include composite body and interior panel, new bogie system and structure, mass transit components drive train, improved propulsion and control system, as well as regenerative and pneumatic brake system. It has 20%-23% more passenger capacity than the current KL monorail.

Made-in-Malaysia monorail launched
Tuesday November 27, 2007
By SHAHANAAZ HABIB
TheStar



Local pride: (From right) Scomi CEO Shah Hakim Zain, Najib and Asmat
inspecting a Scomi monorail train at the Matrade convention centre in
Kuala Lumpur yesterday.


KUALA LUMPUR: Malaysia has unveiled another first – its very own homegrown monorail.

The Sutra monorail was developed by the Scomi Group over the last 12 months.

Deputy Prime Minister Datuk Seri Najib Tun Razak, who launched the new monorail yesterday, called it a significant milestone.

“Today, Scomi has become one of only three major players in the world’s monorail business and has successfully developed a homegrown Malaysian monorail system ready to take on the world,” he said yesterday.

Najib said it was a pleasure to note Scomi aggressively pursuing deals in countries like India, Saudi Arabia, Thailand, Vietnam, Bangladesh, Pakistan, Syria, Egypt and South Korea collectively valued at RM6bil.

He said regions like Eastern Europe and South America with emerging economies, too, were worth looking into because it was only a matter of time before they needed to consider investing in modern, relatively-inexpensive and practical modes of public transportation.

At a press conference later, Najib said that Scomi, being a homegrown company with very high value local content, had an advantage and was in a “very competitive position” to be considered for monorail projects in the country.

He said the global world was very competitive and it was essential to position Malaysia and Malaysian companies internationally.

“We must build our reputation so that our name is synonymous with reliability, quality, technology and competitive pricing,” he said.

Chairman of Scomi Group Bhd Tan Sri Asmat Kamaludin said total investment for the Sutra monorail was about RM35mil including for research, development and factory expansion.

He said 30 personnel members including 23 engineers and experts in areas of structural and mechanical engineering, design, quality, safety and procurement worked on it for 12 months at Scomi’s manufacturing facility in Rawang which was equipped with its own 1km of monorail test track.

Scomi bidding for RM6b monorail jobs
By Adeline Paul Raj Published: 2007/11/26
BusinessTimes




Quote:
At home, Scomi has proposed in its submitted bid in mid-November that its newly-launched Sutra be used for the Penang monorail project
SCOMI Group Bhd, which launched its second generation monorail yesterday, is bidding for some RM6 billion worth of monorail contracts at home and abroad, its top official said.


Chairman Tan Sri Asmat Kamaluddin said the group is in discussions to supply monorails to countries such as India, Vietnam, Saudi Arabia, Bangladesh, Pakistan, Syria, Egypt and South Korea, through alliances.

At home, it is vying for the Penang monorail project, in partnership with Malaysian Resources Corp Bhd and Penang Ports Sdn Bhd.

Scomi submitted a bid in mid-November, proposing that its newly-launched Sutra (Scomi Urban Transit Rail Application) monorail be used, group chief executive officer Shah Hakim Zain said.

"We understand there are four bidders (for the contract), so we have a 25 per cent chance," he said, speaking to reporters after the launch yesterday.

He declined to reveal the value of the bid submitted, saying only that depending on the configuration, it could cost anything between RM67 million to RM100.5 million per kilometre.

Tenders for the 52km Penang monorail contract, reportedly worth RM1.6 billion, closed on November 14.

Deputy Prime Minister Datuk Seri Najib Tun Razak, who officiated the launch, was non-committal when asked when the Government would announce the winning bid.

"I wouldn't know exactly when, we'll have to check," he said, declining also to reveal if it would be within this year, as widely anticipated.

Najib said Scomi was in "a very competitive position" to secure jobs locally with the Sutra monorail given the fact that it was developed at home and had high local content.

The Sutra monorail, on which Scomi invested RM35 million, was developed at its manufacturing plant in Rawang in just a year.

The group wants to export the Sutra, especially to cities in Asia. In Malaysia, it also sees prospects for the monorail in densely populated cities such as Johor Baru, Batu Pahat and Malacca.

"Our goal is to establish ourselves a strong position in the rail industry, a plan which we will execute over the next five years with our current and future products," Asmat said.

According to Shah Hakim, there has been huge interest in monorails from Asian cities in the last eight to 12 months, mainly because of rapid urbanisation and the increasingly high cost of oil.

Monorails, he said, are an effective transportation solution, with a set of six-car trains helping take off 17 buses from the road.
