Heavy rainstorms and subsidings (re. ShiTai)

Personally I would doubt that a major quality concern is at hand here.
If I would count every case where a rainstorm or heavy rain causes train delays or subsidings even on trunk lines back here in Germany, I'd going insane for sure. Sometimes natural phenomenae that you simply can't avoid are occuring, you just can't help it but to clean up the mess afterwards.
From what I can extract from these internal damage report from the ministry, subsiding of the track base occured at the three stretches at km 178.910 (64.2 cm), km 158.300 (16 cm) and km 106.300 (9.2 cm) respectively, resulting in forced speed limitations and massive disturbance in order of train service and safety. These subsidings where in order classified as one severe railway construction quality failure and two common quality failures officially.
Also the punishments for the contractors involved in the planning, construction and monitoring of these stretches are rather severe, considering the "minor" nature of these subsidings: withdrawal of tender bidding rights concerning big and medium projects for the Railway Construction Bureaus No. 3, 12, 13 (10, 5 and 5 projects), including compensations for the fiscal and material losses etc..

Sichuan-Tibet railway to start construction in September

2009-09-01



Construction of the Sichuan-Tibet railway will begin this month, scol.com.cn, a Sichuan-based news portal reported Tuesday, with details on the railway's scale, direction and number of stops recently released by the China Railway No 2 Bureau in Chengdu, capital of Southwest China's Sichuan Province.

The train will have a designed speed of 200 kilometers per hour, taking about eight hours to travel the 1,629 kilometers-long rail line between Chengdu and Lhasa, capital of Tibet Autonomous Region.

There are currently two ways to get from Chengdu to Lhasa—driving the No 318 national highway which takes three days and rail travel from Chengdu, Shaanxi and Qinghai to Lhasa, which takes about 45 hours.
The railway's construction will have to overcome quite a few complicated geographic conditions, such as frozen earth, landslides, cold weather and lack of oxygen due to high-altitude in some parts, and rock slides.

The railway was delayed once before due to construction difficulties and lack of investment.

However, an unnamed person in charge of the project said those factors aren't an issue this time around. "We don't have such problems now in terms of construction technology and investment."

China's existing railway to the Tibet Autonomous Region is the Qinghai-Tibet railway which runs 1,956 km across the Qinghai-Tibet Plateau from Xining, capital of neighboring Qinghai province, to Lhasa. It went into operation on July 1, 2006.

On a side note, a rainstorm in early July caused sections of the Shijiazhuang - Taiyuan HSR to sink into the mud, some by over 60 cm. This caused emergency repairs and travel delays.

Goes to show that faster isn't always better.
The fact that this was a high speed track means nothing. This sinking would have occurred if the tracks carried trains at conventional speeds.

I'm referring to the speed to construction, not the speed of the trains. Something gets compromised at the speed and price the Chinese are building mega-projects.

Dammit, I spent two days on the Chengdu-Qinghai-Lhasa railway, and now people can soon take the trip in eight hours?
But yeah, I guess it will take a loong time to build that one. The railway I took had been built over decades, and it moved around eastern Xizang for a reason...

川藏铁路将于9月开工传闻不实

新华网北京9月2日电(齐中熙 范超)近日,中国有媒体报道称川藏铁路将于9月开工。记者从中国铁道部核实,该传闻不属实,川藏线正式开工时间尚未确定。

铁道部有关负责人表示,川藏铁路是列入全国铁路网中长期规划的一条重要线路。沿线地质环境复杂,正在开展前期工作。一些勘察工作还未开始,目前还不能确定具体开工日期。

此前有媒体报道称,“川藏铁路9月底开工”“《新建铁路川藏线成都至朝阳湖段环境影响报告书(简本)》正式对外公布,首次披露了该铁路的建设规模、线路走向、站点设置等”。

这位负责人称,这只是成都市一小段工程,没有代表性,不能代表川藏铁路开工。

据悉,目前成都到拉萨主要有两条路:一是公路国道318线,全程耗时3天;二是T22次列车经宝成线、青藏线到达拉萨,单边耗时近45个小时。

I thought too that it would be too difficult for trains to climb the steep slopes from Sichuan to Tibet.

Sichuan-Tibet railway project delayed

2009-09-03

Construction on a highly anticipated rail line linking Chengdu in Sichuan province to Lhasa in Tibet will not start this month, according to the Ministry of Railway, contradicting recent media reports.

The railway's planners are still examining intricate and difficult geological conditions along the proposed lines, according to the ministry spokesman, who was quoted by Xinhua News Agency.

A new start date has not been set, the spokesman said.

The railway's construction will have to overcome frozen earth, landslides, rock slides, cold weather and a lack of oxygen due to high altitude in some places.

The proposed railway will span 1,629 km, 650 km of which will be in Sichuan. Trains will travel at a maximum speed of 200 km per hour and will take only eight hours to reach Lhasa, the capital of the Tibet autonomous region, according to Wang Minghui, deputy chief of the Chengdu railway administration.

The rail line is expected to be finished in eight years with an investment of nearly 54 billion yuan ($7.9 billion) in State funds.

Travelers now have two ways to reach Lhasa from Chengdu: by National Highway No 318, which takes three days, and via Train T22, which takes nearly 45 hours.

"Because only one train leaves Chengdu for Lhasa every other day, and vice versa, it is quite difficult to get tickets," said Chen Zhuo, an official with the Chengdu railway station.

Construction of the Sichuan-Tibet railway is expected to propel economic and tourism development along the line.

The Hengduan Mountains near the line have an abundance of natural resources, including water, vegetation and minerals, said Li Changping, chief of the Ganzi Tibetan autonomous prefecture in Sichuan.

The Yulong Copper Mine near the mountain in Tibet has a proven reserve of 6.5 million tons of copper, first among the country's copper mines.

Eighty-two counties and districts along the line in Sichuan and Yunnan provinces and Tibet boast snow-capped mountains, grasslands, and Tibetan and Buddhist cultures.

Update on Daqin Railway

Daqin Railway records world's largest annual freight volume
June 24, 2009

Daqin Railway's coal transport volume totaled 340 million tons in 2008, and is expected to reach 380 million tons this year, which is 3.8 times as much as its originally designed capacity. This is according to the 9th International Heavy Haul Conference held in Shanghai on June 22.

Therefore Daqin Railway has become the world's largest railway in terms of annual freight volume. China's railway industry, represented by Daqin Railway, has made significant innovative achievements in heavy-haul transportation technologies, ranking among the world's top level and winning widespread recognition from peers around the world.

Jiaoda Microunion CTC System Safely Increases the Efficiency of Daqin Railway
04 August 2009

FZj-CTC independently researched and developed by Beijing Jiaoda Microunion Tech. Co., Ltd. was formerly and successfully applied on 1 August 2009 to Daqin Railway, which centralizes the traffic control of the whole line by its control center and at the same time ensures maximum transportation efficiency of the line. This sets an example for China’s heavy-load railway.

Brief information of Daqin Railway
Daqin Railway, from Datong in Shanxi Province to Qinhuangdao in Hebei Province with a total length of 653 km, is the first double-track electrified heavy-load railway of China to transport coal. The upstream of the line connects Shanxi, Shannxi and western Inner-Mongolia, whose coal reserve amounts to 60% of the total coal reserve of China. The downstream of the railway line reaches 26 provinces, municipalities and autonomous regions as well as 15 countries and regions. As China’s strategic artery which “transports coal from the west to the east”, Daqin Railway transports nearly 18% of the coal transported by all the railways of China. A great number of 20,000-ton and 10,000-ton heavy-load trains run on it. With high density and high quality heavy-load trains, its transportation capacity is increasing year by year. In 2008, its targeted transportation capacity was 350,000,000 tons.

Due to complexity of the technical work of the stations, shunting operation, density of the trains, and the many types of traction engines of different performance, such as 10,000-ton and 20,000-ton ones, all these increase the work load of the dispatch staff and make it more difficult to ensure safety and transportation efficiency. The key to increase the transportation capacity of Daqin Railway, reduce redundancy and improve returns is to centralize and automate the traffic control, that is, to adopt CTC System.
Microunion Tech. Co., Ltd. independently researched and developed the CTC System

In 2004, Beijing Jiaoda Microunion Tech. Co., Ltd. set up its CTC department, which gathered a group of elites led by Dr. Wang Xiujuan, a member of the “CTC Group” of China’s Ministry of Railways. After one year’s research and hard work, they successfully developed FZj-CTC, the centralized dispatching system, in 2005. And the system has passed preliminary technical examination of experts of the Ministry of Railways.

Successful application of FZj-CTC to Daqin Railway
Daqin Railway is the first CTC project of Beijing Jiaoda Microunion Tech. Co., Ltd., which involves the construction of CTC system for 46 stations of the whole line including 11 large stations and 9 unattended stations. The project was initially commissioned at 3 stations and the testing section of Daqin Railway in June 2007, which was successful and got technical approval of the Ministry of Railways. In the second half of 2007, construction of CTC system for the whole Daqin Railway started.

In June 2008, construction of CTC system for the whole line was completed and CTC was tested to centralize traffic control of the whole line. During the period, the company made many modifications and improvements to the system in order to be consistent with the progress of the construction of Daqin Line and the owner’s actual demands. On 1 June 2009 FZj-CTC was formally commissioned for Daqin Line.

Successful running of CTC makes it possible for the traffic control of Daqin Railway to be done by computers so that such information as dispatch order, shunting list, running permit and receiving route forecast, etc. can be conveyed through the network of the system and wireless communication. It sends out orders to run the trains rapidly and accurately, monitor the stations’ signaling system and the running state of the train, track the location of the train and the departure and arrival time of the train in a real-time manner. The successful application of CTC system reduces many procedures for the traffic control of Daqin Railway and provides convenient, fast and accurate services for the operation of the trains.

Following the Daqin Line, Beijing Jiaoda Microunion Tech. Co., Ltd. undertook the construction of CTC for the entire Qiancao (Qian’an – Caofeidian) Line in early 2008. The system had been successfully put into operation at 12 stations by 1 April 2009. The successful application of CTC system to these two heavy-load transportation lines provides convenience for heavy load transportation. It relieves the intensity of traffic control when 20,000-ton and 10,000-ton heavy-load trains are running in high density. And it improves transportation efficiency, ensures safety, and realizes the target of “reducing redundancy and increasing efficiency” for railway industry.

China unveils high-speed railways
By Shirong Chen
BBC News, China analyst

China has announced plans to build 42 new high-speed railway lines over the next three years.

In a breakthrough, China has developed trains that can run on both high-speed and normal lines, said railway official Zhang Shuguang.

A 500km/h train will be tested by the end of next year, Mr Zhang said.

China will have added 13,000km of high-speed lines by 2012, shortening journey times considerably for the expected seven billion annual passengers.

Journey times from the capital Beijing to most provincial capitals will be as short as seven hours, said Mr Zhang, the Chief Engineer of the Chinese Academy of Railway Sciences.

He revealed the plans at a science and technology conference in the city of Chongqing.

Overcrowding

Four north-south and four east-west links are taking shape across China's vast geography.

Construction on the Beijing-Shanghai line is in its second year. The section from Wuhan in central China to Guangzhou in the south will be completed in December, shortening the journey time to four hours.

Mr Zhang said China's breakthrough in developing trains that can run at high speeds on both normal tracks and specially-laid high-speed lines will greatly enhance the network's efficiency.

Overcrowding is often a problem on Chinese trains, especially during peak periods such as the National Day holidays and the Chinese New Year.

The country is investing heavily to expand its railway system by 2020.

When the high-speed network is completed in 2012, it will be able to carry more than seven billion passengers annually, Mr Zhang said.

By then, the existing system will have been expanded by about 20,000km to more than 110,000km.

China CNR sells 20 locomotives to New Zealand

BEIJING, Sept. 11 (Xinhua) -- China CNR Corporation Limited, one of the country's top two train makers, agreed Friday to export 20 diesel locomotives to New Zealand.

This will be the first time that China-made locomotives will be exported in batches to a developed country.

The contract was signed Friday between LORIC Import & Export Corp. Ltd., CNR's foreign trade arm, and New Zealand's KiwiRail, a state-operated railway company.

The first six locomotives will be delivered on May 19, 2010, and the remaining 14 locomotives on Aug. 19, 2010.

KiwiRail manages more than 90 percent of the railway operation in New Zealand, which currently has 4,700-km track lines. New Zealand has been a traditional market for U.S. locomotives for years.

CNR president Cui Dianguo said the project would help the company to develop new markets among developed countries, as this project demonstrated the firm's "ability to provide locomotives with up-to-date technology for developed countries".

CNR is reorganized from China northern Locomotive and rolling Stock Industry (Group) in June, 2008.

New Zealand is the first developed country to recognize China's market economy status, and also the first developed country to negotiate a free trade agreement with China.

8 builders hurt as scaffold collapses (Shanghai - Beijing express railway)

Shanghai Daily
By Dong Zhen
2009-9-18

EIGHT migrant workers were injured after a scaffold collapsed yesterday at a Shanghai-Beijing express railway construction site in Minhang District. It was the second collapse on the project's construction sites in a month. On August 19 a crane collapse killed four workers at a site in Jiading District.

In yesterday's accident, the workers, all from central China's Hunan Province, fell from the 7-meter unfinished scaffold about 7:55am in Beidi Road of Minhang's Huacao Town. The men mostly suffered bone breaks and bruises. Last night, six were still under medical observation in hospital while the others have been released. "A steel bar hit my chest and knocked me down," said Huang Kuncheng, 52, who was working on the ground. The man most seriously hurt suffered a broken pelvis and had blood in his urine but remained in stable condition, Changning District Hospital said. Workers said they were pulling up steel bars to complete the scaffold structure to be used for molding concrete pillars for the railway.
