like I said, Dispatching station, drivers of the two trains, there must be fault with one of them, should be a human failure instead of ATS fault

What kind of human failure do you mean? A well working control system halts the train even if the driver is sleeping.

Well with such speeds (even at 250km/h) and intervals (at least according schedule it was about 10 min) there should be automatic emergency system that should stop all traffic, just like on Beijing Shanghai line 10 days ago!

Perhaps it also suffered some electric interference by storm. Thunderbolts are still visible in this video from the crash site:

Maybe both, thunder damages signal system and the first train, then some human error didnt stop the second train. Just like the accidents happened in German Maglev test line and Shinkansen, these kind of end collision usually attribute to many factors.

IIRC Chinese HSR uses in-cab signalling, so when the first train failed it failed to send the stopping signals to the next train. Although theoretically speaking when the system detects one failed train it should stop all trains.

A senior technician working in an unnamed northern railway bureau also give the same brief analysis with yours, but he also said D3115 is under Nanchang bureau's supervision while D301 under Shanghai's supervision.

北方某铁路局(抱歉,不能提供具体信息)动车检修所一工程师致描述了事故原因:D3115属南昌局管辖,在温州遭遇雷击停车,雷击破坏了列车的信号释放系统,导致铁路无法检测有车停在路轨,D301属上海局,正常运行,迎头追尾。目前中国动车班次较密,一条铁轨上,车间距离为10分钟路程

Supervision, etc. does not matter. If the system does not stop the later train without ANY human interference, even if the train broken down has not any electricity, then it is only appliable for the speed of 80 km/h, not the triple of that.
In a similar case even the German PZB system of the 1930's would automatically halt the second train, even if the train driver is sleeping.

system worked, but was manually overridden. human error. Therefore supervision authority is very important.

the ones who made the decision for manual override should be shot.

Can we confine the discussions about the crash to one China thread, please? I believe they have quite a comprehensive discussion going in the High Speed Rail thread (and considering this was a CRH train, it would probably better placed there). Thanks guys!

Turkmenistan to purchase 50 locomotives from China

Monday, August 08, 2011 - Turkmenistan will buy 50 locomotives from a Chinese company, local media sources reported on Monday.

The Turkmen government will buy 10 diesel locomotives for freight trains and 40 shunting locomotives, which move trains in rail yards for repairs and preparation for future rail trips, the Turkmenistan.ru news agency reported on Monday. Turkmenistan will buy the locomotives from China’s China National Machinery Import & Export Corporation and the CSR Ziyang Locomotive Co., Ltd.

As part of the contract, Turkmenistan will also buy spare parts for the rail cars. The price of the deal was not specified in the report.

Turkmenistan is in the midst of building railroads that will connect the Central Asian state to the Persian Gulf and to Kazakhstan. Turkmenistan received its first-ever loan from the Asian Development Bank (ADB) to finance construction of railway for the transportation project.

China to export 40 bullet train locomotives to Georgia

A major Chinese electric locomotive manufacturer, CSR Zhuzhou Electric Locomotive Co, Ltd, won a bid to export 40 bullet train locomotives to the country of Georgia.

The company, based in the city of Zhuzhou in central China's Hunan province, is expected to deliver the locomotives and accessories to Georgia in September 2012, Zhu Jianfei, the company's spokesperson, said on Tuesday.
The locomotives will be used in bullet trains travelling at a speed of 120 kilometers per hour between Georgian cities in the mountainous Caucasus region, Zhu said.

Due to the complicated terrain and climate of the Caucasus, the locomotives will feature technology used in the locomotives of subway and light rail trains, he said.

Zhu said winning the bid is a significant step for China's high-tech railway products in tapping markets in the Caucasus region as well as markets among members of the Commonwealth of Independent States and European countries.

Make sure when you click on the link it doesn't automatically redirect to "usa.chinadaily.com.cn" as that URL is unreachable. It'll do it if it detects that your IP address is in the United States. I had to click the link a couple of times to get the link to work.

How is 120 km/h a bullet train? Is it just shaped like a 9 mm?

China's railway passenger traffic sets record high during holiday

2011-10-08

BEIJING, Oct. 8 (Xinhua) -- China's railways carried a record total of 67.3 million passengers from Sept. 28 to Oct. 7, as many Chinese went on a travelling spree for the weeklong National Day holiday, the Ministry of Railways (MOR) said Saturday.

The figure was up 5.8 percent over the same period last year, with a daily record of 8.9 million passengers boarding trains on Oct. 1, or National Day, the ministry said.

It said high-speed trains saw passenger surges during the holiday and ticket supplies fell short of demand on some popular routes.

A total of 2,453 additional trains operated during the holiday to meet travel demands, the ministry said.

Difficulties in purchasing tickets have been a major source of complaints against the ministry in recent years, as demand for train tickets is always high during the holiday season.

The ministry has promised to expand ticket booking by phone and online and cut fees for ticket refunds in order to improve service quality.
