The top-speed was not cut in the wake of Wenzhou crash; it was cut earlier than that, when the new Minister of Railway took office earlier last year. This has been a common misconception.

The crash on July 23 in Wenzhou , Zhejiang , which killed 40 people and injured 172 others, forced the government to lower the top speed of high-speed trains from 350km/h to 300km/h.

I think they'll open the Beijing-Wuhan HSR and the Harbin-Dalian HSR this year

Hmmwv, have you got some information about the current status on the Shanghai-Kunming HSR and the so called Lanxin HSR one?

Both lines are progressing nicely, Shanghai-Kunming suffered a tunnel cave in three weeks ago but fortunately the trapped workers were rescued, that 2066km line is now scheduled to open in 2015. Lanxin 2nd Double Line has received higher priority and investment increased this month, it's set to open in 2014.

A lot of people are saying that the trains were slowed down because HSR trains fundamentally can't run at 350km/h without too much wear and tear. Rubbish. The AGV has been designed by Alstom France to have the same operating costs and 30% less energy use at 360 km/h as the TGV at 300 km/h.

This is what you get when a company with over 30 years experience in the field starts from a clean sheet and looks at every aspect of HSR design with all their knowledge and understanding, rather than gets someone else's design and thinks they can do better in 12 months.

Any hard numbers and research data comparing wear and tear+running costs of AGV/TGV and trains used in China?

The question is how on earth a lightning strike could take out the safety system? With so much redundancy built into railway safety systems it litterally should be impossible. Even if the train command central were to burn down the system is designed to work perfectly fine.

They don't, there are thousands of lighting strikes every year over CRH tracks but only a small fraction of them will cause problems to the signaling system due to various safety and redundancy systems, out of that number only some will cause train stoppages. The safety system worked in the Wenzhou crash, that's why the trains were stopped/held in place at station prior to the accident, however the system was then manually overridden despite knowing all safeties are off. It's the lack of safety culture in the middle management (under pressure from upper management to keep on schedule rate) that needs to be, and is being addressed.

Where are the 6655 km which do not belong in the plans?
Now that the plan is 40 000 km by end of 2015, where are the remaining 17 345 km to be built?

China removes safety hazards in railway sweep

BEIJING, July 31 (Xinhua) -- Railway authorities said Tuesday that they have removed more than 300 safety hazards from the country's railway system in an overhaul launched after a fatal high-speed train crash last summer.

Authorities uncovered 359 problems that posed potential risks to rail safety and solved 324 of them over the past year, the Ministry of Railways said in a report.

The remaining hazards will be eliminated by the end of this year, the ministry noted.

The report came about one year after a high-speed train slammed into a stalled train near the eastern city of Wenzhou on July 23, 2011, leaving 40 people dead and 172 injured.

The incident was blamed on faulty signaling equipment and mismanagement. Fifty-four officials were punished and 54 trains supplied for the high-speed railway between Beijing and Shanghai were recalled for modifications.

Signaling equipment on other railways was checked and lightning diffusion equipment was reinforced at more than 1,000 stations, the ministry said in its report.

Lightning caused the signal failure that resulted in the crash in Wenzhou, a previous official probe found.

The ministry imposed stricter standards for high-speed rail construction and equipment, ordered high-speed trains to run slower and beefed up emergency response preparations after the deadly accident.

The country has seen no major rail accidents since the beginning of this year, while nine people died in three accidents that occurred in railway construction, down 60.9 percent and 57.1 percent year on year, respectively, according to the report.

What kind of 'safety hazards' should I think of?

I have to say the Chinese are responding well to the unfortunate accident that happened last year.

The line out to Urumqi will suck up a few thousand kms on its own. Kunming, Guanxi, Guilin, smaller lines in less known provinces, spurs, upgrades to the current non-CRH plan, etc.

At 350kph, a can full of soda is a safety hazard. A rock, a board, a branch, a brick, anything that you can think of, and is common all over the roads and sidewalks and byways and right of ways of China, is a safety hazard.

This is a good sign. It means that a culture of maintenance and safety is being created, one that did not exist prior. Lots of someone's are out walking tracks picking up hazards.

I think some thought that the Chinese would build this world class CRH system and then let it decay, becoming the world's joke.

Wrong.

Why would they order trains to run slower?
