Progress of maglev train & technology in China

Its not a Maglev.

Why not? This train is propelled by magnetic levitation. Read my post at #9

Maglev (derived from magnetic levitation) is a transport method that uses magnetic levitation to move vehicles without touching the ground.


From wiki:

The first commercial maglev people mover was simply called "MAGLEV" and officially opened in 1984 near Birmingham, England. It operated on an elevated 600-metre (2,000 ft) section of monorail track between Birmingham International Airport and Birmingham International railway station, running at speeds up to 42 km/h (26 mph). The system was closed in 1995 due to reliability problems.[11]

Its not a Maglev. .

It's not a regular train, it's low-speed maglev for suburban rails which is not just built in Changsha but Beijing.

Maglev is about technology, not about speed. I cannot stop laughing reading your reply.

 

[GS Zhou]

why do you call it stupid? I loved the ride. May be it is not cos efficient ? (the few times I rode it it was only may be 10% full if that)

I come from Shanghai. And most of the Shanghai residents think this is a white elephant. As what Andrew Jin just pointed out, this line would only make sense, if it could be extended to the Hongqiao Aiport/HSR Station, or at least extend to Puxi (the west side of the Huangpu River)

For those who question the speed,

Maglev - Wikipedia, the free encyclopedia

There are currently only 3 operating Maglev system in the world according to Wikipedia, in China Shanghai, Japan Linimo and Korea Incheon Airport.

Linimo (Tobu Kyuryo Line, Japan)

The commercial automated "Urban Maglev" system commenced operation in March 2005 in Aichi, Japan. The Tobu-kyuryo Line, otherwise known as the Linimo line, covers 9 km (5.6 mi). It has a minimum operating radius of 75 m (246 ft) and a maximum gradient of 6%. The linear-motor magnetically levitated train has a top speed of 100 km/h (62 mph). More than 10 million passengers used this "urban maglev" line in its first three months of operation. At 100 km/h (62 mph), it is sufficiently fast for frequent stops, has little or no noise impact on surrounding communities, can navigate short radius rights of way, and operates during inclement weather. The trains were designed by the Chubu HSST Development Corporation, which also operates a test track in Nagoya.[76]​

Incheon Airport Maglev - Wikipedia, the free encyclopedia

The Incheon Airport Maglev[1] is a maglev system in South Korea planned to open in 2016.[citation needed]. It links Incheon International Airport to the Yongyu Station and Leisure Complex while crossing Yeongjong island.[2] The maglev system was co-developed by the Korea Institute of Machinery and Materials (KIMM) and Hyundai Rotem.[3][4][5] It is planned to be 6.1 kilometres (3.8 mi) long, with six stations and a 110 km/h (68 mph) operating speed.[6] It is the world's third currently operational Maglev system, following the Shanghai Maglev Train and Japan's Linimo. The majority of construction was completed by November 2012.

Two more stages are planned of 9.7 km and 37.4 km. Once completed it will become a circular line.

Hyundai-Rotem is using the same technology for the Leningrad MagLev System, the first urban commuter Maglev system in Europe.[7]​

There is another similar maglev line in Changsa.

From the Changsa city official website,

Changsha to pilot its maglev by year-end
Updated: 2015-03-25

Changsha maglev project, the first low-speed maglev line in China that has independent intellectual property rights, will be completed and go into trial operation by the end of 2015.

Upon its completion, the distance between Changsha South High-speed Railway Station and the T2 terminal in Huanghua Airport will be reduced to 10 minutes. The project will transform the Changsha South Station into a comprehensive transportation hub, ensuring seamless transfer among maglev, subway, and high-speed rail.

More importantly, it means that the city of Changsha will take the lead in building itself into a modern integrated transportation hub with high-speed rail, air traffic, inter-city rail, low-speed maglev, subway, as well as highway.

“The Changsha maglev project will draw on the management experience from similar projects in Shanghai, Hong Kong, Japan, and South Korea. And advanced technologies from both home and abroad will be put into use for its construction,” said Wu Xiangming, chief adviser to the Changsha maglev project, who used to be the head of Shanghai maglev project.

Wu said that the low-speed maglev has the advantages of being safer and quieter, with smaller turning radius, better climbing ability, as well as low cost. At present, the Changsha maglev project has completed accumulative investments of 1.5 billion yuan ($ 241.44 million).

The project has established strong scientific research and consulting teams and carries out close technological cooperation with several institutions and universities in conquering multiple technical difficulties.

When completed, it will be the first low-speed maglev line in China completely built by Chinese engineering. It is also expected to be the flag bearer of the maglev industry in Central China’s Hunan province.

Maglev is a transport method that uses magnetic levitation that gives it its name to move vehicles without touching the ground. With maglev, a vehicle travels along a railway using magnets to create both lift and propulsion, thereby reducing friction and allowing higher speeds.

Well done, China. Haters are going to hate because they can't accept reality. Reality is China is going to the top regardless what anyone says or does.

 

[Roybot]

Its not a Maglev.

You mean HSR! High Speed Railway. Maglev, stands for magnetic levitation. And any train running on this technology, regardless of the top speed is a Maglev.

Just like 100 Km/hr suburban train is also an EMU and a 300KM/hr HSR is also an EMU!

China's first home-grown maglev goes on trial

The first Chinese middle-low speed magnetically levitated (maglev) rail is to go on trial before the end of the year, authorities said on Saturday.

The 18.5 km track, links the south railway station with Huanghua airport in Changsha, capital of central China's Hunan Province. The track allows maglev trains to run at a maximum speed of 100 km per hour.

The construction of low-cost maglev trains, made by Zhuzhou Electric Locomotive Co. Ltd. in Hunan province, began in May 2014. A total of 3.5 billion yuan (565 million U.S. dollars), or 82 percent of total investment, have been used.

The company said its maglev trains are safer, quieter, and have a smaller turning radius, making them more environmental friendly.

The world's first commercial maglev system operates on a 30-km stretch between downtown Shanghai and the city's Pudong airport. The German-made maglev went into operation on Dec. 31, 2002.

After massive railway success, China pivots back to maglev technology
By Zhang Tianrui (People's Daily Online) 16:14, November 28, 2016

Chinese train manufacturer CRRC Corporation announced that it will begin construction of a new maglev railway, which will allow trains to travel at up to 600 kilometers per hour.

The first prototype is expected to be delivered in 2020, and the test track will be built in Shandong province.

Based on electromagnetic induction, maglev trains are suspended over railway tracks. Thanks to the consequent reduced friction, the travelling speed of maglev trains is twice that of the fastest high-speed train, and close to that of airplanes.

Germany, Japan and the U.S. started to develop maglev transport system in the 1970s, with the aim of improving the capacity and efficiency of their public transport. In 1990, China's Railway Bureau proposed the construction of a Beijing-Shanghai high-speed railway. However, debate raged for seven years about whether the railway should utilize maglev or wheel-rail technology. The latter was ultimately adopted by the State Council in 2004.

Since then, China’s wheel-rail technology has remained at the center of the railway industry. However, when a mid-speed maglev railway in Changsha opened to traffic in May, maglev technology returned to the spotlight. Additionally, a mid-speed maglev line in Beijing, linking the Shijingshan and Mentougou districts, is currently under construction.

As for radiation caused by maglev rails, which is of great concern to the public, Xie Hailin, manager of the maglev branch of CRRC Corporation, explained that electromagnetic radiation inside maglev train carriages is subject to the same limits as radiation in underground carriages. At the same time, compared with underground railways, mid-speed maglev trains consume less energy, cost less, and can be constructed more quickly.

The first high-speed maglev railway opened for business in Shanghai in 2003. The Shanghai line shortens the travel time between Pudong International Airport and Shanghai's central business district to just 13 minutes.

Test line for ultra-high-speed vacuum maglev train to be built in 2017
(People's Daily Online) 16:40, November 29, 2016

A test line for the ultra-high-speed vacuum maglev train will be built in China in 2017, experts revealed at a rail transportation conference on Nov. 27.

At the conference, professor Zhang Weihua of Southwest Jiaotong University showcased the latest technologies in high-speed rail transportation, including evacuated-tube high-temperature superconducting maglev trains. High-speed maglev trains boasting speeds of up to 600 kilometers per hour are being developed in China, attendees learned.

“The first medium-low speed maglev line, independently developed by China, is now operating smoothly in Changsha. This is a good model for the promotion of maglev technology. Currently, we are actively developing high-speed maglev trains,“ said Qian Qingquan, an academician with China’s Academy of Engineering.

The second generation evacuated tube developed by the team.​

According to previous report by Chengdu Business News, Southwest Jiaotong University has completed a test of the evacuated-tube HTS maglev system, which was developed by Professor Zhao Yong and his team.

“We think the speed of maglev trains will reach 600 to 1,000 kilometers per hour, fast enough to replace airplanes,” Zhao said.

The team successfully lowered pressure in the tube to 1,335 pa – or just 1 percent of air remaining in the tube. They also increased the average speed of the maglev train to 82.5 kilometers per hour under normal pressure.

As of May, work on the system was progressing well.

​

“The speed has been increased to 100 kilometers per hour under normal pressure,” Zhao explained. With improvements of the vacuum technology, speeds will continue to increase dramatically.

Zhao and his team developed the world's first evacuated-tube HTS maglev test line in 2011. The tube is 3 meters in diameter with a lowest pressure of 2,000 pa. In his second-generation system, tracks were "hung" on the wall of the tube, which increases centripetal force on the running train, as well as speed and stability.

Tracks are "hung" on the wall of the tube.​

However, Shen Zhiyun, an academician with the Chinese Academy of Engineering, expressed concern about the high costs associated with building vacuum trains.

“There is no big problem technically, but the cost is too high. One kilometer of subway costs 800 million RMB, and even 1 billion is not enough to build 1 kilometer of evacuated-tube HTS maglev tracks,” he said.

Beijing's first rail line using magnetic levitation technology is scheduled to start running next year, with engineers now testing the new trains, city officials announced on Sunday.

The overhead maglev line, named S1, will run in the west, from Shijingshan district's Pingguoyuan to Shimenying in the mountainous Mentougou district. It will stretch about 10 kilometers and have eight stations.

The travel time between the two locations, currently connected only by bus, will be cut by two-thirds to just 20 minutes, according to an anonymous official from the Beijing Major Projects Construction Office quoted by Beijing Daily.

"It will take only the time it takes to eat a fast-food meal to travel the entire line," he said. "Plus, the maglev train is more stable, quieter and better at climbing hills compared with normal trains."

Once finished, S1 will connect with the subway's Line 1 and the western extension of Line 6, which is under construction.

Built in neighboring Hebei province, the first maglev train was delivered to the capital on Dec 16. According to officials, the line will have 10 trains, each with a capacity of 1,000 passengers.

The line will make scenic spots in Beijing's western suburbs more easily accessible to residents and tourists.

"As much as I enjoy the serenity there, it takes me about two hours by bus to go to Tanzhe and Jietai temples in Mentougou," said Liu Bo, 25, who lives in the city. "When the new line opens, I can go to the temples more often.

"It's been a while since the work began, so all I hope now is that it opens soon."

Construction on S1 began in 2011 after months of debate, with public fears raised about potential radiation. However, experts have dismissed such concerns.

"The line employs closed magnetic field technology that elevates the train about 1 centimeter above the track to reduce friction. It leaks no magnetic influence outside the controlling 'red line' distance, therefore it won't affect nearby residents," Li Jie, chief engineer of the maglev project, told Beijing Daily.

"As for passengers inside the train, as the radiation is non-ionizing like radio waves, it's neither accumulative nor harmful. At most, passengers may feel a bit warmer."

Although rare compared with conventional subway trains, maglev trains are not new to China. A high-speed maglev service has run from Shanghai's Pudong International Airport to downtown Longyang Road since 2002. Trains travel at up 430 km per hour.

A medium-to-low speed maglev line that uses similar technology to Beijing's S1 also opened in May between central Changsha, capital of Hunan province, and the city's international airport.

Central Chinese cities to build more maglev lines

2017-03-01 09:55

Xinhua Editor: Gu Liping

Central China's Hunan Province is preparing to build more middle-to-low speed magnetically levitated (maglev) rail lines after the successful launch of the first domestic line in the province in 2016.

The first Chinese middle-to-low speed maglev rail line started operation in May 2016 in the provincial capital, Changsha. It travels between Changsha's south railway station and the airport, with a maximum speed of 100 km per hour.

Changsha plans to build another maglev line in the city's Xiangjiang New Area, the first "state-level new area" in central China, according to the city's development and reform commission earlier this month.

After the train's launch, it will only take 30 minutes to travel to the south railway station, and 45 minutes to Changsha Huanghua Airport.

Another maglev line is expected to be built within the year, in the province's Zhuzhou city. The 27.9-km line will have 24 stops and start operation after a three-year construction period, according to the city government.

Middle-to-low speed trains produce little noise, according to Peng Qibiao, head of the maglev research institute of CRRC Zhuzhou Locomotive Company.

"Maglev trains are safer and cheaper compared to current metro and light rail cars. They can also operate in severe weather, with zero emissions," Peng said.

Beijing is also expecting its first medium-low speed maglev rail line, which will start operation this year.
