Project manager Mass Rapid Transit Jakarta announced that work started on the underground section of Jakarta’s first metro line on April 4.
Excavation began at Hotel Indonesia Traffic Circle, where there will be an underground station. A guide wall is due to be completed within three months, which will allow a diaphragm wall to be built. The timescale for the completion of this and subsequent station works is four years.
In May the city authorities announced the winners of the tenders for the three underground civil works packages. Sumitomo Mitsui Construction Company and PT Hutama Karya is undertaking the work at Hotel Indonesia Traffic Circle, whereas the other two packages are being carried out by a consortium of Shimizu, Obayashi, Wijaya Karya and Jaya Konstruksi.
Two of the three elevated civil works packages will be carried out by a Tokyu-WIKA consortium, with a consortium of Obayashi, Shimizu and Jaya Konstruksi responsible for the other.
Revenue operations on the 15·7 km line are planned to start in early 2018. An 8·1 km northern extension is planned as the second phase.
TRANSIT took note of the unfortunate news that the Selangor Government will move ahead with studies for the Kinrara Damansara Expressway, also known as KiDEx or the KiDEx “skyway” (a falsely romanticized name just as false as the pictures on their website)
Transit took note of the proposal from 4 ADUN in the Selangor State Assembly (representing Petaling Jaya) that the route of the proposed Kinrara Damansara Expressway (a.k.a. “KiDex” or “KIDEX Skyway“) would be better utilized for public transportation.
TRANSIT took note of this interesting article which discusses the Open Day that Prasarana is holding to share information about the LRT Extension Programme Open Day which will inform the public about the Ampang & Kelana Jaya LRT extension plans.
TRANSIT has taken note of the Malaysian government’s plans to expand KL Monorail service by introducing 4-carriage trains with greater capacity, as well as extending the KL Monorail service to Taman Gembira along Jalan Klang Lama.
Malaysian monorail builder Scomi Rail has been given the contract to provide the 12 new 4-carriage trains, which will be a variation on Scomi’s SUTRA model. More information about the SUTRA can be found in this article or at the Scomi Rail website. Check out this video showing the actual SUTRA train operating on the test track at the Rawang facility.
According to the various reports in the Malaysian media, the KL Monorail is already 35% over capacity. More interestingly, the different articles (thank you Scomi for collecting them into News flashes 1, 2 & 3) have different numbers about the capacity of the new monorail carriages compared to the older ones. One says that the older carriages can carry 98 passengers and the new carriages will have a capacity for 128 passengers – and then claims that this is an almost 40% increase – which it is not
Do the math: 128 / 98 x 100 = 130 … meaning the increase is much closer to 30%.
And just to make things more confusing, another article claimed numbers of 107 / 135 (old & new carriages respectively).
So we have to wonder where the media are getting their sources and why Scomi would allow different numbers to be made public about their product.
Even more upsetting is the claim that with the new 4-carriage trains the line will have a carrying capacity of 6400 passengers per hour per direction. If we extrapolate back we would assume that line capacity with the 2-carriage trains are in the range of 3,000-3,200 passengers per hour per direction.
These are strikingly poor line capacity numbers that are more in range with a middle-capacity Bus Rapid Transit system or a tram/streetcar! And the monorail cost us 40 million USD per km!
Monorails have a place in our public transport plan, but a line-capacity of 3,000-3,200 (or even 6,400) passengers per hour per direction is a shockingly low number that does not fully explore the potential of the monorail as a public transport technology – or a solution for Kuala Lumpur.
Anyways, the article about the monorail extension is below. You can also see a jpeg. image of the article’s cover and inside page. The inside page also includes this slightly inaccurate graphic, outlining the various routes planned under the Urban Rail Development Plan. We really wonder when certain organizations within the Malaysian media (and they know who they are) will improve on their fact-checking and publish accurate stories and information – rather than unclear stories & speculative information as they do now.
