      The only good monorail, is an old monorail (maybe). Schwebebahn Wuppertal since 1901->


      Monorails? There is something almost touching about avarice and stupidity when they get together and blatantly hang out there for all to see.


      I first looked at monorails for city transport of all kinds of types and stripes back in 1970, and on a number of grounds they looked awful then and they still do today. I have my own long list on this, but if you wish we might have some fun starting a collaborative list under the title of something very elegant such as "Why monorails suck".


      I am amazed that these discussions are still taking place and that there are cities and eventual sponsors that take them seriously. There is a monorail mafia that shows up wherever at the drop of a hat to show their stuff, often offering generous credits and other forms of compensation to see that their job gets done. I haven't made an effort to keep up. But I do remember some recent salvoes in parts of India, also Bogota, São Paulo, Curitiba, and a certain number of US cities that just don't know when to let a bad idea go.  (Check out the historical stuff on this in the Wikipedia. Pretty good.)


      What I don't understand is why they are not simply laughed at and set aside for more serous things.


      But then again, perhaps there is something that I fail to understand.


      Educate me.

      PS. Here's a nice exercise for you if you wish to dig a bit. Go to the New Mobility Partnerships at www.newmobility.org and on the top menu click Knoogle (yes, it's an ugly word) and once there pop in "monorail". This will then take you on a lightning  survey of more than eight hundred sources, projects and pogroms looking at sustainable and at times unsustainable transport in countries around the world. Interesting.

      Subject: Re: Mumbai monorail project looks to reduce CO2 emissions ???



      we are developing these parameters for BRT also, and there is also a give back on co2 from construction, though usually its smaller, and if you need to build the elevated BRT (like they are doing in Ahmadabad in places) there is a lot of concrete there also.  its not a BRT/mrt thing.  i am trying to integrate the evaluation criteria to look at mrt and brt and other options using similar methods.  i am in Guangzhou for the opening of the BRT here and one very nice feature is its integration with the metro system, maybe the first time we get nice full integration.  the BRT is not on a corridor with mrt in the long term plan, so its additional and not competitive.

      Walter raises an important issue. There is indeed a payback time. But it
      isn't necessarily 20 years for systems that have frequent service and carry large numbers
      of people all day. And even when it is 20 years, keep in mind that metros and railways
      are around for a century or more. The tunnel for the first line in London. the Metropolitan
      Railway, was opened in 1863 and is still in service today. That is true sustainability.

      If the point is that BRT avoids this problem, we have been over this before. Points to consider:

      1) Sometimes a tunnel is the only way to get both decent capacity and high performance to the places
      that need it. Once a tunnel is needed anyway, the case for rail strengthens.

      2) I heard the presentation at WRI about Ahmedabad two weeks ago where the speaker said "build BRT,study Metro" which got laughs from the audience. I point out that just the opposite also happens. "Build Metro, study BRT" was the case in Delhi. This difference in incubation time must be taken into consideration when evaluating the carbon reduction. How much extra would have been emitted waiting for the go-ahead for the first BRT line?

      3) What are the real options on the table? If the choice is between building a Metro and building a highway, I will take the Metro. If the choice is between BRT and Metro, then it needs to be studied closer. I don't automatically pick either one.

      Quoting Walter Hook <whook@...>:

      sudhir from CAI Asia just ran some numbers for metro projects and CO2.  If
      you include all the construction related CO2, they come out negative for a
      large number of years, and to get positive co2 impact you need to push the
      project time line out something like 20 years or more. i imagine monorails
      would not be quite as concrete intensive but may be close.   Interesting to
      note the mention of Lanzhou.

      Mumbai monorail project looks to reduce CO2 emissions

      By Lisa Sibley
      Published 2010-01-27 09:22
      Kuala Lumpur, Malaysia-based Scomi Group, a global service provider mainly
      in the oil and gas industry, said today its trial run of India's first
      monorail car for a project in Mumbai has been a success.
      The Malaysia-listed company also specializes in urban transit systems, with
      an emphasis on India, China, the Gulf states, and Brazil. The trial run
      occurred yesterday, also a national holiday, the Republic Day of India.
      The monorail is expected to prevent 200 tons of carbon dioxide emissions
      daily. The proposed structure is also considered environmentally friendly
      because it won't obstruct sunlight or trap excessive emissions. In
      it's expected to be quieter than other modes of transportation.
      Scomi India's Country President Suhaimi Yaacob said in a news release the
      project's focus is on sustainable mobility, reduced urban congestion,
      improved reliability, and comfortable travel.
      Other cities looking to reduce mass transport emissions include China's
      Lanzhou, which is working on a comprehensive urban development plan linking
      a new city center with a rapid bus transport system, expected to result in
      cleaner, more economical mass transportation system (see China's Lanzhou
      makes plans to reduce mass transport emissions
      <http://cleantech.com/news/5429/lanzhou-mass-transport-system>  [1]).
      Scomi's engineering division and partner Larsen & Toubro, India's largest
      engineering and construction conglomerate, secured $545 million for the
      Mumbai Monorail Project in November 2008, and are expected to complete the
      project by 2011.
      Scomi is tasked with delivering 60 cars, making up 15 sets of four-car
      trains. Each four-coach monorail is expected to be able to accommodate
      600 passengers, carrying a total of nearly 300,000 daily commuters.
      The monorail project is expected to have a 20-kilometer (12.4 mile)
      route between Jacob Circle and Chembur, a suburban neighborhood in eastern
      Mumbai, with one central depot and about 18 user-friendly stations. Chembur
      is located about 22 kilometers from downtown Mumbai and considered a
      point for travelers to Pune.
