Inspector indicated it's a random inspection which found the problem, but insisted the problem will be discovered even after commercial service has started because test train will run regularly to take measurement.

Really? I was expecting something along the lines of this:

@hmmwv

Thx, have you got these informations from an updated chinese source?
Because i can't read articles in chinese.

And the Changsha - Kunming HSR will be completed in 2014 too?

A friend of mine recently was in China. He used the Beijing - Tianjin HSR.
It was fantastic.

Probably China in future will need even more expressways, HSR, airports and subways.

Rail Line Collapses in China

Failure of New Unopened Section, After July Accident, Adds to Industry's Woes

Updated March 13, 2012
By NORIHIKO SHIROUZU
Wall Street Journal

image hosted on flickr

Excavators in central China's Hubei province were at work on Monday to repair a
section of high-speed rail line that had collapsed after rains.


BEIJING—A section of new high-speed rail line in central China has apparently collapsed two months before it was scheduled to go into use, in the latest blow to the nation's already troubled high-speed rail ambitions. The extent of the collapse wasn't clear. The state-run Xinhua news agency and other local media said Monday that a 300-meter (almost 1,000-foot) section of a high-speed rail line intended to connect the Yangtze River cities of Wuhan and Yichang collapsed Friday, apparently following heavy rain. The collapse, near the city of Qianjiang in China's Hubei province, happened on a rail line that had already undergone test runs.

The reports mentioned no casualties and offered few details. Xinhua said hundreds of construction workers were rushing to repair the affected section. However, Hou Xinyue, a local railway official in Qianjiang, disputed the media reports, saying the incident affected 4.3 miles of the rail line, a larger amount of track than reported by state media. Mr. Hou, deputy director of a local office that oversees one 27-mile section of the 175-mile Wuhan-Yichang line, said rail tracks on an above-ground platform sank as the foundation gave way, possibly due to heavy rains. Mr. Hou said the rail bureau in Qianjiang was still investigating the accident. He didn't disclose further details.

While the Xinhua reports also blamed heavy rains as the main trigger, other local media cited a recent report by the state-run magazine Time Weekly, which said that engineers working on the construction of the Wuhan-Yichang high-speed line had complained of a sloppy construction method used by builders on another section of the same line, with soil substituted for rocks in the railway bed. Details of the Time Weekly report couldn't be confirmed. A person who answered the phone Monday in the information office of the China Railway 12th Bureau Group Co., which is in charge of the project, had no comment and declined to give her name. An official for the media office of the Qianjiang municipal government said his office also had no comment. Calls to the Ministry of Railways went unanswered.

The accident followed a fatal high-speed railway crash last July that called into question the pace and quality of China's high-speed-rail buildout, which officials had touted as a signature program and a sign of the nation's rising technological might. That accident—which involved one bullet train rear-ending another in the eastern China city of Wenzhou—killed 40 people and injured 172. Chinese government reports following a state-led investigation have blamed flawed signal equipment and poor communications procedures as well as corruption. The accident prompted Chinese authorities to slow expansion of the bullet-train system.

The incident reported on Monday came as Railways Ministry officials started to boast again that the country is committed to pushing ahead with its high-speed-rail expansion program. China's central government conceded late last year that China's high-speed-rail-network expansion had gone too fast. The network is already the world's largest and is planned to stretch some 16,000 kilometers (about 10,000 miles) when it is completed in 2020, at an estimated total cost of more than $300 billion.

Are there any photos of the collapsed section where we could see the actual collapse?

I doubt that. This is likely again another example of "overblown" reporting. It is more likely just a case of road base being washed away or sunk. It is still serious no doubt but is materially different from "Collapsed".

It is always interesting to read through the "word" game in some of the western media.

^I think we won't be seeing an actual visible dip, because in an earlier post it was already stated that the actual level of subsidence was only 4mm.

That's not visible to the naked eye.

Stop that, stop that right now.

This conversation has been had many times, it's annoying and proves nothing other than your own opinion. Believe waht you want, but don't go round smack talking the media because they wrote things you don't like. Same goes for the anti-china folk on here too.

Chinese Official Blames Soft Soil in Latest Rail Setback

Updated March 13, 2012
By NORIHIKO SHIROUZU
Wall Street Journal

BEIJING—A Chinese official confirmed that numerous sections along a seven-kilometer, or four-mile, stretch of a new high-speed railway had sunk into the earth and would take one month to repair, as additional details of the latest blow to China's high-speed train system came to light.

Xinhua/Zuma Press - Workers reinforce the section of the new high-speed rail line that collapsed in central China's Hubei province.

Wang Zujian, director of the railway-construction bureau for the central China province of Hubei, said the incident occurred in part because the rail tracks were constructed partially on mounds of packed construction soil and gravel resting on unstable wetlands. He said workers have rushed to the scene to reinforce the rail tracks and their foundations. He noted, however, that it would likely take about a month to finish the repair work. The line—a nearly 300-kilometer track connecting the Yangtze River cities of Wuhan and Yichang—had been tested and was set to go into service in May. He didn't say whether the opening of the line would be postponed, but it appeared likely as new test runs would be needed after the repair work.

Mr. Wang disputed a local media report that construction standards were to blame. While the state-run Xinhua news agency has blamed heavy rains as the main trigger of the sinking, other local media cited a recent report by the state-run magazine Time Weekly, which said that engineers working on the construction of the high-speed line had complained of a sloppy construction method used by builders on another section of the same line, with soil substituted for rocks in the railway bed. Details of the Time Weekly report couldn't be confirmed. "We hired third-party supervision agencies with strict standards," Mr. Wang said.

The Hubei railway construction official said the incident affected a 7.2-kilometer (about 4.3-mile) section of the Wuhan-Yichang high-speed rail line. He said the high-speed rail line had been built to tolerate sinking of as much as three millimeters. But in Friday's incident, along numerous sections of the 7.2 kilometer stretch, the foundation for the train tracks sank 3.33 millimeters to 4.22 millimeters, requiring the construction bureau to repair the affected sections, he said. Xinhua blamed heavy rains as the main trigger of the incident, but Mr. Wang on Tuesday disputed that view. "If the rain could destroy a railway line, then what kind of a project is that?" he said. It wasn't clear whether his statement of the construction on the railway on unstable ground amounted to an acknowledgment of bad planning.

The incident followed a fatal high-speed railway crash in July 2011 that called into question the pace and quality of China's high-speed-rail buildout, which officials had touted as a signature program and a sign of the nation's rising technological might. That accident—which involved one bullet train rear-ending another in the eastern China city of Wenzhou— killed 40 people and injured 172.

Details of the latest incident didn't emerge until Monday. State media initially reported that a 300-meter (almost 1,000-foot) section had collapsed. Xinhua said Tuesday that authorities were still investigating the cause of the accident, quotingSun Shengjie, deputy manager of China Railway 12th Bureau Group Co.—the company in charge of the construction of the entire Wuhan-Yichang bullet-train line.
