The sun is rising over a quiet city, where the lights inside 13 new rapid transit stations turn on and the first station staff make their way down the relatively unused escalators to prepare to open the platforms for the first wave of customers.

The familiar hum of a linear induction motor system populates the station as the first of 15 four-car trains rolls in from the maintenance yard, ready to board passengers for the first service of the day.

If you think I’m describing an event in Vancouver, you would be wrong because I am describing what’s happening right now in a major Japanese city, one that decided to build a brand new rapid transit line with the same SkyTrain technology developed in Canada and pioneered here in Vancouver.

See: New subway line opens in disaster-hit Sendai – The Japan Times

Sendai, Japan is the city that was hit hard during the March 11, 2011 Tohoku earthquake and tsunami. The completion of the new Tozai Line, a 14km rapid transit subway with both underground and elevated stations, has turned the page for the city, marking its vibrance and prosperity as it progresses in its recovery from the devastation of 4 years ago.

I went back to Sendai for a business trip, and it also happened to be the day the Tozai line opened to the public. It was crazy! The city and its people are treating it like a big event!

Videos and photos of the launch celebrations show thousands of people making use of the new system, and celebrations ranging from idol girl groups performing on the station platforms, local sports team mascots out to celebrate, men in samurai outfits, traditional dance performances on board the trains, and picnics at the park beside the train’s visible elevated section. It is a lively hustle and bustle and the mood appears to be as festive as when I visited Sendai just 4 months ago to attend the city’s most famous Tanabata Festival, as part of my 1-year Japan studies journey. It is arguably the biggest occurrence in the city since this August and the biggest revolution for the city since the first steps in recovery were made after 2011.

SkyTrain technology was developed in Canada and pioneered right here in Vancouver.

Since the first km of demonstration track opened in early 1983 here in Vancouver, SkyTrain technology has made its way around the world with just over 20 systems complete or being proposed in 15 cities worldwide. We have reinvested in it and expanded our system several times, yet we’ve been overtaken by a certain Guangzhou, China that has made a monstrous investment in this technology with over 99km of track – reaching 130km by next year.

Sendai’s will to revitalize their city with the help of a technology pioneered here in Vancouver, Canada should be seen as a wonderful treat and a mark of our contributions to this technology’s progress, and a reminder of the big impacts we can make with choices that we would otherwise deem irrelevant. Sendai’s choice of SkyTrain technology will help the city fast-track its ongoing recovery from the events of 4 years ago.

The line will serve 80,000 riders a day next year, with an additional 3% more estimated to come each year and grow the system’s ridership. According to the schedule on the city’s website, trains will run every 3-4 minutes during peak hours and no less frequently than every 7.5 minutes at off-peak times and weekends – an excellent service standard for a medium-sized city of 1 million people.

The new line is already enabling new transit-oriented development nodes in the city, maximizing the line’s potential and giving a nod to the transit-oriented development practices that Greater Vancouver pioneered for every city in North America.

In an area around Arai Station, work to establish a new community of nearly 20,000 people is progressing. Public apartments have been built for those affected by the tsunami, with people moving there from areas closer to the Pacific coast as part of a collective relocation program. (The Japan Times)

We should celebrate a technology that’s made an impact around the world

As a result of the practical research for three years from Fiscal 1985, we confirmed that low-cost subway “Linear Metro” that has been developed as a public transport is suitable for regional hub city as a semi-main metropolitan line or branch line. For this reason, the Japan Subway Association established the “Linear Metro Promotion Headquarters” within the association in October 1988.

Japanese researchers started studying linear induction motors (LIMs) as train propulsion in 1985. After Osaka built Japan’s first LIM line (the Nagahori Tsurumi-Ryokuchi line), it was found that the city had saved approximately 20% in construction costs. This is one of the key advantages that come with LIMs – the less-complicated motors enable trains to have lower platform heights, which  means tunnels can be significantly smaller and less costly without impacting the quality of service. There is no doubt that with the majority of Sendai’s new subway line tunneled, millions in cost savings were found with the use of SkyTrain technology.

This same advantage was directly to blame for the use of an existing railway tunnel on our Expo Line SkyTrain downtown, a choice that saved us hundreds of millions of dollars as a traditional light rail system would have required new and larger tunnels to be dug under our downtown core.

“The new line is a symbol of development for the disaster-hit Arai district. I hope the Tozai Line will play a major role in leading the city.”
– Emiko Okuyama, Mayor of Sendai (The Japan Times)

Sendai’s system brings the amount of in-service SkyTrain technology systems from 17 to 18. 14 cities/areas are currently using SkyTrain technology, and a 15th (Okinawa Island, also in Japan) has declared its use for a major future transit investment.

I am pleased to hear about and report on this successful launch, and I encourage all of us in Vancouver to cheer this Japanese city and its people in celebrating a brand new era of progress and motion.

Malaysia confirms SkyTrain technology for 36km Klang Valley line

Featured above: A Mark II train on the region’s existing Kelana Jaya Line

It’s official: SkyTrain technology has been confirmed in Malaysia for a brand new, 36km rapid transit line to be built on the outskirts of Kuala Lumpur. The new ‘Klang Valley LRT Line 3’ will begin construction at the beginning of next year, and is expected to open for revenue service in the year 2020. An alignment study has been completed, and the project owner has distributed the construction tenders just last week for the new line so that the detailed design process may proceed.

The Klang Valley line will intersect with the existing Kelana Jaya Line on Kuala Lumpur’s RapidKL network. The Kelana Jaya Line was built on the same propulsion and driver-less technology used on the SkyTrain system in Metro Vancouver, and uses the same Mark II vehicles manufactured by Bombardier. In addition to the Klang Valley Line, RapidKL is also currently in the process of completing a 17km extension of the Kelana Jaya Line, which will open in 2016. Here’s a short description of the new line from RapidKL:

Designed to ease traffic congestion in the Klang Valley and connected to the current LRT Kelana Jaya Line and the upcoming MRT Line 1 Sungai Buloh–Kajang, the proposed alignment of the LRT3 is currently being finalised by the Land Public Transport Commission. LRT3 aims to connect Bandar Utama to Klang, covering 36km, and will comprise 25 new stations.

Daryl’s take reported on the Klang Valley Line last year, then known as the “Shah Alam Line” (SEE: Previous article) when its potential use of SkyTrain technology was merely a possibility. This has now been confirmed in the alignment studies.

VIEW NOW: Klang Valley LRT 3 Environmental Assessment [PDF]

The environmental impact assessment for the Klang Valley/LRT3 project, which was uploaded by observers on the SkyscraperCity forum, mentions that the vehicles on the proposed transit line will be the “similar to those used on the Kelana Jaya line” – indicating that they will be the exact same vehicles or a close variant, using the same linear motor propulsion technology, and driver-less operation.

The Light Rail Vehicle train, similar to those used in the Kelana Jaya LRT Line, will be used. The train can be configured to a 2, 4 or 6 car-vehicle train. The dimension of each car is 20 m long x 2.65 m wide x 3.44 m high. Each car will have a minimum of 36 seats and 6 passenger doors (3 doors on each side). It will be full Automatic Train Operation driverless system.

While the assessment did not specifically mention the use of linear motor propulsion, it did specify a vehicle height of 3.44m, matching the vehicle height of the Mark II trains on the Kelana Jaya line and thereby requiring the use of linear motor “SkyTrain technology”, as the height would not permit standard rotary motor propulsion due to its requirement of a higher platform. As a comparison, the regional network’s Ampang Line trains, using standard rotary-motor propulsion, have a height of about 3.9m. The assessment also specified a 5% maximum grade, requiring linear motor trains for safe operation. For rapid transit rail lines, standard rotary propulsion trains are generally limited to 3% maximum grades in order to accommodate for push-pull operations in the event of train stoppages and other emergencies.

The initial operation will use 54 2-car trains, at a 2-minute headway throughout the day. There will be an end-to-end time of 51 minutes on a running speed of 80 km/h, for an average speed of 42 km/h. Here are some additional highlights of the new Klang Valley line:

Largest SkyTrain technology expansion in recent history

At a whooping 36km from end-to-end, with 25 stations, the line will be the largest expansion of SkyTrain technology in recent history. I believe this will assuage some critics in Metro Vancouver who have claimed that the expense of SkyTrain technology prevents us from building larger-scale expansions. This is 36km of track being built at once, within 4 years!

6-car trains!

Guangzhou Metro Line 5
Yep, 6-car trains! Pictured: Guangzhou Metro Line 5

The new line will be designed to accomodate 6-car trains on platforms that are 120 m long – 50% longer than those used on the Expo and Millennium Lines. This will not be the first example of a SkyTrain technology transit line with trains longer than 4 cars (the Toei subway Oedo Line in Tokyo runs 8-car trains), but it may be the first done with Mark III trains if Bombardier is awarded the rolling stock contract.

330,000 daily passengers after 30 years

The line is being designed to meet projections of carrying 330,000 daily passengers by the year 2050, which will make it one of the busiest SkyTrain technology lines in the world – and possibly the busiest using Bombardier’s Innovia trains if those are used on the new line. Opening-day ridership is estimated at 70,000 riders.

82km of SkyTrain technology

With the existing Kelana Jaya Line and its extension, the Klang Valley line’s 36km addition will result in over 80km of SkyTrain technology rapid transit in operation in the Greater Kuala Lumpur area.

This will be the second largest network in the world, short of the Guangzhou Metro which is already operating over 100km of linear motor rapid transit and continues to expand that. If the rolling stock is provided by Bombardier, then RapidKL will surpass Vancouver’s SkyTrain to become host to the world’s largest SkyTrain technology system with Bombardier trains.

CSR-Zhuzhou consortium bids, debunks “SkyTrain is proprietary” myth

Naza proposes to finance up to 90% of LRT3 – The Star

According to a recent news report, Chinese rolling stock manufacturer CSR-Zhuzhou, which has previously provided linear motor technology for the Guangzhou Metro and the Changsha Maglev, has bidded for the Klang Valley line in a consortium with local construction firm Naza Engineering & Construction. The Naza-CSR consortium have offered to fund up to 90% of the project cost, in an effort to lure the contract.

If the consortium wins the contract, the trains will then be built by CSR-Zhuzhou rather than Canada’s Bombardier. They will still have to fit the specifications in the alignment study, meaning that linear motor propulsion trains – likely based on the ones in service in Guangzhou – will be used.

A Naza-CSR win would mark the second time in history (the first being Tokyo) that a SkyTrain technology rapid transit system is operating vehicles from two different manufacturers, effectively debunking a commonly spread idea throughout this region that “SkyTrain technology”, which was originally developed in Canada, is proprietary. The Greater Kuala Lumpur region is familiar with CSR-Zhuzhou: they had previously provided rapid transit vehicles (of standard rotary propulsion tech) for the region’s older Ampang Line.

Bombardier eyeing Klang Valley Line, sets up resources in Malaysia for prospective bid

Bombardier targets sales in the Asia Pacific to reach 25% in the next 5 years – XSInvest

A representative from Canada’s Bombardier Transportation (the manufacturer of our Expo and Millennium Line SkyTrain cars) has previously stated that the company is eyeing a train order for the proposed Klang Valley Line project, as well as other proposed heavy rail rapid transit projects throughout the region. Bombardier Rail opened a new office in Kuala Lumpur last year to facilitate operations in Malaysia and throughout Asia, accomodating 100 engineering, project management, systems integration and signalling specialists. If Bombardier bids for the Klang Valley line, they will then be in open competition with CSR-Zhuzhou and any other bidders for the line rolling stock.

Debates over: the line is opening in 5 years

LRT3 Tender Documents Ready for Collection – RapidKL

While we can’t seem to decide on transit projects or technologies here in Metro Vancouver, the Klang Valley region has progressed quickly and the project owner has already started the call for construction tenders. This is not just a proposal at this point – the consultations have been finished, and the project is moving forward. The line will be open for service just 5 years from today.

About Kuala Lumpur’s “Rapid Rail” system

Kuala Lumpur’s integrated rail system. The Kelana Jaya line is in magenta.

Kuala Lumpur’s RapidKL network is like a clone of our SkyTrain system overseas: the system is composed of several grade-separated, automated (driverless) rapid transit lines. Some use the same linear induction motor propulsion technology and Bombardier Mark II vehicles used on SkyTrain here in Vancouver, whereas others use standard rotary motor technology (as with the Canada Line). The Ampang Line, the first rapid transit line, used standard rotary propulsion and was opened in 1996. This was followed by the 1998 opening of the Kelana Jaya Line, the fully automated linear-propulsion line that looks and works exactly like our SkyTrain system, with the same Mark II trains.

The 29km Kelana Jaya Line is built with both overhead sections and bored tunnel sections through the city core. It is the busiest and most popular rapid transit line in metropolitan Kuala Lumpur with 160,000 riders daily [1], and was for a long time the only rapid transit service in the Klang Valley metropolis that broke even (revenues paid for operations costs) until the Ampang Line, which had historically fallen a few thousand riders short from breaking even [1][2], was equipped with thec system to itself become fully automated (driverless) [3]. Both lines are currently receiving extensions that are due to open at around the same year the Evergreen Line is opened here in Vanouver.

The extensions are shown in the above map (note the unnamed stations near the bottom). Kuala Lumpur’s Rapid Rail system has been immensely successful since its opening, being major money generators for the regional rapid transit system and the biggest drivers of ridership and high-density development. SkyTrain technology helped the fares on RapidKL’s rapid transit lines remain completely unchanged for 10 years [4], despite hydro bill increases for the operating company, as a result of continually increasing ridership [5]. The RapidKL network is considered the “key revenue-generator contributor” for Prasarana, the regional transportation authority if the Klang Valley [6]

SkyTrain technology declared for 60km outer belt metro in Tokyo

“SkyTrain technology” (linear motor propulsion, with automated operation) has been declared for a major investment in rail rapid transit in the outer boroughs of the city of Tokyo, Japan – the world’s largest metropolitan area with over 38 million people residing.

Map: Proposed "Metro 7" and "Eight Liner" rapid transit line circling outer Tokyo. The Tokyo Metropolitan Bureau of Transportation wants to use SkyTrain technology to reduce the project costs of this transit line.
Map: Proposed “Metro 7” and “Eight Liner” rapid transit line circling outer Tokyo, which will run under the city’s 7th and 8th Ring Roads. The Tokyo Metropolitan Bureau of Transportation wants to use SkyTrain technology to reduce the project costs of this transit line.

The proposed lines – initially two separate projects codenamed “Metro Seven” and “Eight Liner” – will be merged into a single project that is 59.7km long, with 42 stations.

There is an additional 13.7km extension to Tokyo’s Haneda Airport (bringing the total project length to a whooping 73.4km) under consideration. It has not been finalized as part of this proposal and is pending further study, likely given that other Haneda-oriented rail projects are currently being considered by other operators.

Case study

I was given a link to a study on the Itabashi ward website, which concluded that the use of SkyTrain technology would significantly save costs and improve the project business case, due to significant reductions in tunneling and land acquisition costs.

LINK: 平成25年 – 度区部周辺部環状公共交通に係る調査 – 概報告
English: 2013 Fiscal –Outer Ward Circumferential Public Transit Study – Summary Report

The Tokyo Metropolitan Bureau of Transportation (Toei) has proposed to build and operate the subway line with public funds, a rarity in a country where most major railways are built and operated by private companies.

Linear Motors Save Costs

The new metro line in Tokyo will use a new specification called “Smart Linear Metro“, which is identical to the 69km SkyTrain technology railway line proposed in Okinawa. Short, 12m long cars – similar to Vancouver’s Mark I SkyTrain vehicles – will enable a further reduction in tunnelling height, curve radius and land costs compared to 16m long “standard linear metro” cars already in use in Fukuoka, Yokohama, Kobe and other cities, which themselves allow for smaller tunnels than standard 20m rotary propulsion metro cars. To enable the high carrying capacity required for a Tokyo metro line, multiple-car, articluated units will be used.

Through the reduction in tunnelling and land acquisition costs – made possible by the key advantages of linear motor propulsion in lower floor heights and tighter curve radii – the use of SkyTrain technology is estimated to save taxpayers the equivalent of $300 million Canadian dollars.

Slides from the case study (tap to enlarge):

Trains will initially operate every 3 minutes during peak times on the higher-demand western segment, whereas a 5 minute frequency will be used on the eastern segment.

Popular in Japan

Japan is one of the world countries that has recognized the benefits of SkyTrain technology and pushes a widespread application of SkyTrain technology in every new railway project. There are now 9 lines in 6 cities running, under construction or under consideration. The new circumferential line will be the 9th such line in Japan, and the 20th such line in the world.

The Toei Oedo subway has been operating since 1991, and had one extension in 2001.
The Toei Oedo subway has been operating since 1991 and is one of the busiest Tokyo subway lines.

Toei has previously demonstrated SkyTrain technology successfully on the Toei Oedo Line, a major Tokyo subway line with a ridership of over 850,000 passengers daily. The Oedo Line has operated successfully for over 23 years. It’s no surprise that with this record, Toei would want to build another such line.

New SkyTrain technology metro in Sendai, Japan opens 2015

sendai-map
Sendai Subway map showing the new Tozai Line (east-west line in blue)

A brand new rail rapid transit line in Sendai, Japan – which is using linear induction motor propulsion technology (“SkyTrain technology”) – is on track to open next year (2015), with final construction activities and train testing underway. The Tozai Line will be 14km long, and feature a mix of underground and elevated sections.

The use of SkyTrain technology is now confirmed by more than a concept photo, as the linear-motor rolling stock has arrived and pictures have surfaced showing linear motors on the subway track. These initial trains have passed their testing, keeping the line on-track to open exactly one year from now on December 6, 2015.

A new video featuring the rail transit project, showing the unveiling of the SkyTrain-tech rolling stock and construction progress, was recently updated to YouTube. As part of these unveilings, school children were allowed to be a part of the event, inspiring a future generation of transit riders.

New construction photos of the Sendai Subway’s Tozai Line has recently hit the internet. The photos below were posted on the official project Facebook page:

The Tozai Line was originally scheduled to open much earlier, but construction was delayed by the devastating 2011 Tohoku Earthquake and Tsunami, which heavily damaged much of the city. The new subway line will therefore be part of the revitalization movement for Sendai City.

Japan is one of the world countries that has recognized the benefits of SkyTrain technology and pushes a widespread application of SkyTrain technology in every new railway project. There are now 8 lines in 6 cities running, under construction or under consideration. Sendai Subway’s new Tozai Line will be the 7th such line in Japan, and the 18th such line in the world.

Sendai’s project is one of seven SkyTrain technology projects concurrently under construction around the world – the other projects are in Vancouver (Evergreen Line), Kuala Lumpur, Malaysia (Kelana Jaya Line extension), Guangzhou, China (Metro Line 4 & 6 extensions) and Beijing, China (Airport Express west and north extensions).

A recent SkyTrain-tech project, announced for the island of Okinawa, Japan, will be the largest one-time SkyTrain technology project in the world at 69km long.

Okinawa, Japan declares SkyTrain technology for 69km railway

Okinawa Railway System - Urban elevated railway station concept

As you may recall (or not, since I have yet to actually discuss anything Japan-related on this blog!), I departed Metro Vancouver in September of this year to pursue a scholarship-supported abroad studies program in Kyushu, Japan. My studies include a transportation research component – and through this, I initially received word that Okinawa would use linear motor cars on its inaugural island railway – a.k.a. “SkyTrain technology”.

As of this week, a number of online articles in Japanese have now surfaced, revealing project details and effectively confirming SkyTrain technology for Okinawa’s first major rapid transit line.

News release: 知事選で高まる気運 リニアモーターを使った沖縄の「普通鉄道」建設構想とは
English: Election momentum growing: plan outlined for Okinawa’s linear motor railway
Translated (Google): [LINK]

This means that linear motors and reaction rails (locally termed in Vancouver as “SkyTrain technology”) will be used to propel trains on the island. Japan is one of the world countries that has recognized the benefits of SkyTrain technology, with 7 lines running or already under construction in 6 cities. Okinawa’s railway will be the 8th such line in Japan, and the 19th such line in the world.

See also: List of Linear Induction Motor Rapid Transit Systems

The news release linked above emphasizes that every candidate for prefectural governor (there is an election coming up in Okinawa!) is supporting the proposed rapid transit line. This is because the line will be 30% cheaper to ride end-to-end than the current express bus service, due to efficiencies for the island’s transit operator. It is expected to cut travel time across the island in half, to 58 minutes from the current 1 hour and 45 minutes by rapid express bus.

There will be two primary segments. The 20km segment between Okinawa City and Naha Airport will feature an urban metro-style service. Trains will initially run every 5 minutes during peak hours, and every 12 minutes off-peak. The 49km segment between Okinawa City and Naga City will be the world’s first intercity railway using SkyTrain technology. Trains will initially arrive every 15 minutes during peak hours and every 20 minutes off-peak.

Map of proposed 69km SkyTrain-type railway in Okinawa

The line will initially use 4-car trains, with 12m long cars – similar to Vancouver’s Mark I SkyTrain vehicles. They will be low-height vehicles capable of running through smaller tunnels.

最高速度は100km/hが目標とされており、長さ12mの車両の4両編成が考えられています。1両あたりの長さが約15.7mである長堀鶴見緑地線の車両が、4両編成で定員が380人なので、12m×4両では単純計算で290人程度の定員があることになります

English: Trains will have a maximum speed of 100km/h, and the government has considered using 12m length cars. For comparison, trains on Osaka’s Nagahori Tsurumi-Ryokuchi line are 15.7m long. Those trains carry 380 people, so we imply that Okinawa’s trains will carry 290 people between the 4 cars.

In order to navigate the island’s challenging terrain, 70% of the proposed line will be in a tunnel, which means the linear motor trains – which have lower train heights and require smaller tunnel diameters – will save the local government billions of dollars in tunneling costs. A standard rotary propulsion railway would have also likely required more tunnels, given linear motor vehicles are capable of handling steeper slopes at higher speeds, avoiding the need for tunnels and landscaping in certain segments.

Case study

With further searching, I was able to uncover a case study document that included conceptual art for the proposed rail line:

LINK: 新たな公共交通システム導入促進検討業務 – 報 告 書 – 概 要 版 – 沖 縄 県
English: New public transit system promotional business case – Executive Summary – Okinawa Prefecture

According to the study, the SkyTrain-type rapid transit line was initially compared on a level playing field with a variety of other transit options – including Tram-Train – a form of ground-level Light Rail Transit (LRT), and Bus Rapid Transit (BRT) – and won against these options, found to be the most worthwhile investment as it would generate the most travel time benefits for local citizens.

The linear motor transit systems examined in the study included the Bombardier ART (SkyTrain) systems in New York and Beijing.

About Okinawa

Okinawa, a well-populated and internationally well-known island south of the 4 main Japanese islands, is contrary to the rest of the country in that it has yet to see any serious developments in rail transit. There is a 12.8km monorail in the main city (Naha), but that is it – the rest of the population uses buses or drives automobiles to travel longer distances.

The new railway will signifcantly improve transit travel times and create a new option to combat rising congestion levels on the Okinawa Expressway, a major toll road crossing the island. The entire railway will be 69km long, which will immediately make it the third longest SkyTrain-technology rail system in the world upon completion. Vancouver’s SkyTrain system, which will grow with the completion of the Evergreen Line – and Guangzhou, China, where three SkyTrain technology lines cover 100km of track – are the only longer systems.

Kuala Lumpur: New 36km SkyTrain line to complement extension

UPDATE – 11th April 2015: SkyTrain technology has been CONFIRMED for the proposed Klang Valley Line.

Today I bring you news from Malaysia! A news release from a few days ago reveals details of a new 36km SkyTrain line to complement an already under-construction 17km extension of the Kelana Jaya line are beginning to surface. The new extension would run from a proposed new transit hub, intersect the Kelana Jaya Line, and then travel through Shah Alam to a terminus at Klang – a city of close to 850,000 people situated 32km west of Kuala Lumpur.

The original regional transportation plan finalized in 2011 [CLICK HERE] proposed that this line would be constructed after 2030; however, a re-examination of the business case in June 2013 has resulted in the project being pushed up to the pre-2020 timeframe. An even newer study focusing specifically on the line details itself has suggested that there are immediate benefits to reap – and with that, the line is now a top priority investment. Construction is likely to begin on the new SkyTrain extension at the beginning of next year, where it will parallel the ongoing extension of the Kelana Jaya Line.

See Also: Greater KL/Klang Valley Urban Rail Development Plan – June 2013 [PDF]

The new plan helps show that the technology we use in SkyTrain is becoming a serious rail rapid transit option for cities worldwide, with expansions of SkyTrain-type lines now well under way in multiple cities – including here in Vancouver, there in Kuala Lumpur, in Sendai, Japan and in Riyadh, Saudi Arabia.

Additional details

The “Shah Alam LRT” will be the second SkyTrain-type line in Kuala Lumpur (or the third if the Kelana Jaya Line extension is considered a separate line). The new line will connect directly to the Kelana Jaya Line and may offer a continuous service onto the line. With its completion, Kuala Lumpur’s RapidRail system will eclipse the SkyTrain system in the amount of in-service linear motor trackage, spanning a distance of 82km before 2020 – whereas SkyTrain (lines using linear induction motor tech) will span just 63km after the completion of the Evergreen Line. This will make Kuala Lumpur’s system the second longest linear motor rapid transit system in the world, after the 100km Guangzhou Metro system.

See also: List of Linear Induction Motor rapid transit systems

The new “Shah Alam LRT” line will complement an already in-service commuter rail transit line, similar to how the Evergreen Line will complement the non-stop West Coast Express service in the tri-cities. The rapid transit stock for the new line can be expected to be built by either Bombardier or CSR-Zhuzhou. Bombardier has been a major supplier for the rapid transit cars on the Kelana Jaya Line (ART 200/Mark II trains), while CSR-Zhuzhou has supplied standard rotary-motor rapid transit cars for the Ampang Line (but is also a major supplier of linear motor cars for the Guangzhou Metro system).

The rapid transit lines are considered the “key revenue-generator contributor” for Prasarana, the regional transportation authority if the Klang Valley [6]

Guangzhou opens world’s newest SkyTrain technology line

I recently updated my List of Linear Induction Motor rapid transit systems [LINK] list to reflect the opening of Guangzhou Metro’s Line 6 – the world’s newest “SkyTrain technology” line, adding 25km of linear motor trackage to Guangzhou’s Metro system. The opening was met with a celebration last week.

SEE LINK: Guangzhou Metro Line 6 opened on December 28

SEE NEWS VIDEO (in Chinese):

The new line is expected to carry 700,000 passengers daily (about twice as much as our SkyTrain system carries) in the first month – making it one of the world’s busiest applications of SkyTrain technology on a rapid transit line. Guangzhou now has 100km of active linear motor rapid transit track – twice the length that Vancouver has on our SkyTrain system. Line 6 has both above-ground sections and tunnel sections; the latter in particular takes advantage of the low-height of linear motor cars, which enables smaller tunnels and cost savings.

Line 6 is very unique among the Guangzhou Metro Lines in that it has the most stations, the most passenger amenities, and offers the most frequent service of any Guangzhou Metro line. Basically, Guangzhou has chosen to build the most important subway line in the city with SkyTrain technology.

Guangzhou Metro ordered almost 200 linear motor rapid transit cars from Itochu and China’s CSR Sifang for Line 6. [SEE LINK]

A recent Vancouver Sun piece [LINK HERE] that I’m planning to send commentary on took note on the apparent obsolescence of “25-year-old SkyTrain technology”. The opening of this new line in Guangzhou, which is a high-capacity application, shows that this is far from true. In fact, there’s new research going on in India [LINK] at the Indian Institute of Technology (Banaras Hindu University) Varanasi to make it the fourth country to offer a “SkyTrain technology” product – after Canada, Japan and China.

List of Linear Induction Motor train lines

A concise list of all current and future rapid transit lines using linear induction motor propulsion technology. There are over 20 in-service or proposed systems across 16 cities/metro areas.
