Shanghai City will try low speed maglev

Zitat

SHANGHAI will invest 150 million yuan (US$18.54 million) to build a 1.5-kilometer low speed trial maglev line within this year, Laodong Daily reported.

If the trial operation is successful, a 20 kilometer maglev line will be built next year, linking the site of Shanghai Expo and Lingang New City near Yangshan deep water port in Nanhui District.

The speed of the trial line can reach nearly 100 kilometers per hour. Though it is slower than the fastest express train, whose speed can reach 160 kph, the new maglev would save energy, cut noise and be more environment friendly, the newspaper quoted experts as saying.

Shanghai built a 30-kilometer maglev line with a total investment of 8.9 billion yuan in 2003, which is the world's first magnetically levitated rail line in commercial use. It links Pudong International Airport with Longyang Road Metro Station in some eight minutes at the speed of over 400 kilometers an hour.

Shanghai Daily news
The city is considering plans to build a low-speed magnetic levitation rail line linking an under-construction deepwater port in Nanhui District with the site of the 2010 World Expo, an official with Shanghai Maglev Transportation Development Company said yesterday.
The company will begin by building a 1.5-kilometer-long pilot line in the southwest of Coastal New Town, which is a part of Shanghai's Yangshan Deepwater Port.
The pilot project is expected to cost 150 million yuan (US$18.52 million) and the train can run to a top speed of 100 kilometers per hour. Traditional light rail lines have a top speed of 80 kilometer an hour.
"The new line will facilitate residents in the new coastal township who travel to downtown," an official surnamed Chen with the company's business operation department told Shanghai Daily yesterday.
He said the low-speed maglev will cost far less to build per kilometer than the rapid maglev line that serves the Pudong International Airport.
He said the low-speed line will cost about 100 million yuan for each kilometer, about one-third the price of the current maglev. He couldn't say how much a kilometer of traditional light rail line costs to construct.

Chen said a test line is needed as the low-speed maglev uses different technology than the existing line. He refused to say if the new line will be completely Chinese built, or if engineers from Germany will work on the project as they did on the existing maglev.

"The low-speed maglev is an ideal choice to solve the city's inner-township traffic problems," said Cai Yifeng, a city planner with the Shanghai Transportation Planning Institute.

"It's possible that the city will plan more low-speed maglev lines in the city's suburban districts," he said.

An area of 5.28 square kilometers has been rounded up for construction of Expo pavilions between the Nanpu and Lupu bridges, mostly in Pudong. The low-speed maglev technology is also being developed by the United States and Japan

Why should a maglev line be slow?

As the online department was writing the story “City will try low-speed maglev,” we were wondering, too, because the story said Shanghai will spend 150 million yuan to build a low-speed maglev. Yes, low speed. Well, isn’t the futuristic maglev famous for its flying speed, which could be as fast as 400 kilometers an hour? Um… As part of the job of the online department is to adapt stories from Chinese media, and Laodong Daily is a legitimate newspaper, we decided to give the story a go.

The story was doing well. It ranked No.3 on the top click list yesterday. The Metro desk of our print edition also asked our science and urban planning reporter Zhang Jun to interview Shanghai Maglev Transportation Development Company to confirm the news. His story, “Low-speed maglev rail could connect port with Expo site“, is among the Top News of the newspaper and is also doing well on the Website’s top click ranking today.

Quick enough, this afternoon, a reader’s email solved our puzzle as it provides more insight into the low-speed maglev technology and the beauty of having it run on the streets of a busy city like Shanghai.

To share the knowledge with our readers, we decided to publish his email on this blog:

Dear Editor,

While Winny Wang’s piece is factually correct, the following excerpt is misleading: “Though it is slower than the fastest express train, whose speed can reach 160 kph, the new maglev would save energy, cut noise and be more environment friendly, the newspaper quoted experts as saying.”

Contrary to the conclusion readers will make after reading Winny’s article, the primary advantage of a low-speed maglev lies in the fact that its low speed makes it better suited for frequent stops as a local “feeder line,” as opposed to a faster long distance “express.” Higher speed maglevs (or trains) are unnecessary and undesirable in systems requiring frequent stops.

Additionally, the lower speed maglev infrastructure is less massive, and therefore less expensive, because it is not handling the additional stresses of higher speeds and heavier vehicles.

Incidentally, the operating and maintenance cost advantages of all maglev systems over conventional rail transport make them highly desirable to deploy, even if the original capital costs end up being somewhat higher.

Truly effective transit systems require highly integrated local, regional, and high-speed intercity or airport connectors. And, as world oil prices rise, electric-powered transit will play an increasingly major role in the way people travel. China’s leadership understands this concept and is moving China in that direction. Unfortunately, America so far lacks leaders with similar vision.
