China's high-speed rail offers model for other countries: World Bank
Source: Xinhua| 2019-07-08 23:53:46|Editor: Mu Xuequan

BEIJING, July 8 (Xinhua) -- China's high-speed railway (HSR) has registered rapid growth and offered many viable practices for other countries considering HSR investment, according to a World Bank report released Monday.

Key factors enabling the growth include the development of a comprehensive long-term plan and the standardization of designs and procedures, said the report, which summarizes China's HSR development.

China's Medium- and Long-Term Railway Plan, which looks up to 15 years ahead, provides a clear framework for the development of the system, according to the World Bank.

Meanwhile, the construction cost of the Chinese HSR network stood at about two-thirds of the cost in other countries, the report said, citing an average of 17 million U. S. dollars to 21 million U. S. dollars per km.

"China has built the largest high-speed rail network in the world. The impacts go well beyond the railway sector and include changed patterns of urban development, increases in tourism, and promotion of regional economic growth," said Martin Raiser, World Bank director of China.

By the end of 2018, the total railway operation mileage reached 131,000 km, five times higher than 1949, while the high-speed railway exceeded 29,000 km, accounting for more than 60 percent of the world's total, according to a recent report by the National Bureau of Statistics.

In China, high-speed rail service is competitive with road and air transport for distances of up to about 1,200 km, while fares are about one-fourth the base fares in other countries, which allows HSR trains to attract passengers from all income groups, the report said.

"Large numbers of people are now able to travel more easily and reliably than ever before, and the network has laid the groundwork for future reductions in greenhouse gas emissions," Raiser said.

Submission @Oxford-Small Tailor, first time I make animation: China's high-speed rail development in 2008-2017. Image source World Bank report "China's high-speed railway development" (English) web link.

According to the report, China's high-speed rail (200km/h and above) has exceeded 29,000km since 2008, far exceeding the sum of the rest of the world. The cost is 30% lower than in Europe, and the fare is only one-fourth that of Europe, allowing people from wider income group to use the high-speed rail (1.7 billion in 2017).

From the point of view of the entire high-speed rail network, the return on investment in 2015 was 8%, and the passenger flow density was 23 million. Although it is only 2/3 of the Shinkansen, it is twice the average in Europe. From a single project point of view, due to the low fare, only the eastern part has passenger flow density exceeds 40 million, where the fare of 350 km/h main line reach of 0.5 yuan/km per person, can repay the principal and interest; But many other lines has passenger flows density of 10-15 million, these low-cost 250 km/h line, can barely cover the operation and maintenance costs.

Construction work on the final section of the Sichuan-Tibet Railway will start shortly, said Southwest China's Sichuan Province Party chief during a press conference at the State Council Information Office (SCIO) on Monday. Analysts said the railway will serve as a major transportation artery linking China and South Asia.

The Chengdu-Ya'an section of the Sichuan-Tibet Railway has started operations, said Peng Qinghua, Party chief of Sichuan Province.

"The completion of the railway will not only drive the regional economy and strengthen the link between Tibet with the inland areas, but it also can serve as a major transportation artery linking China and South Asia," Zhao Jian, an expert on railway economics at the Beijing Jiaotong University, told the Global Times on Monday.

"The Sichuan-Tibet railway will make it possible to build a railway connecting China, Nepal, India and other countries, which will boost the regional economy with convenient transportation," Zhao said.

"Sichuan was the starting point of the southern silk road in history. Now it is the pivot of the Belt and Road Initiative economy belt, linking land and sea," said Peng.

The Sichuan-Tibet Railway will be the second line linking Southwest China's Tibet Autonomous Region to other parts of China after the Qinghai-Tibet Railway.

The line is designed to start from Chengdu, capital of Sichuan Province, passing through Ya'an and entering Tibet via Qamdo. It will then go through Nyingchi prefecture and end at Lhasa, capital of Tibet.

The Lhasa-Nyingchi section is under construction, said Peng. "The 1,000-kilometer Ya'an-Nyingchi section is part of the plan. Bridges and tunnels will cover over 90 percent of the line, that is to say, nearly 800 kilometers of tunnels and 100 kilometers of bridges."

"It is far more difficult to build the Sichuan-Tibet Railway than the Qinghai-Tibet Railway since geological conditions are complex along the Sichuan-Tibet line, with severe geological conditions and disasters such as permafrost, alpine hypoxia, landslides, earthquake zones, and geothermal and rock bursts," Zhao added.

The planned route will go through the Sichuan basin, Yunnan-Guizhou Plateau and Qinghai-Tibet Plateau, climbing from several hundred meters above sea level to the "Roof of the World," at an altitude of more than 4,400 meters.

The railway will cut the travel time from Chengdu to Lhasa from 48 hours to 13 hours.

LHASA, Aug. 3 (Xinhua) -- Construction on a pivotal tunnel on a railway linking Lhasa and Nyingchi in southwest China's Tibet Autonomous Region was completed Friday, marking huge progress of the mammoth project.

The Bukamu Tunnel, located in Milin County of Nyingchi, is 9,240 meters long with an average elevation of 3,100 meters above the sea level. It is also the 37th tunnel being finished, leaving just 10 tunnels to be completed by the end of the year.

Over 3,000 rock bursts were counted during the construction of the tunnel, while the oxygen level inside was merely 19 percent that of the plain areas, said Wang Shucheng, director of the project.

The Lhasa-Nyingchi railway is 435 km long, 75 percent of which are bridges and tunnels. It is expected to be completed in 2021.

China to mass produce 400k/h high-speed trains by the end of 2019
Source:Global Times Published: 2019/8/6 14:08:40

A committee of experts in China has approved a design scheme for high-speed train that could run at a speed of 400 kilometers an hour, and the train will be launched before 2022 to serve the Beijing Winter Olympic Games. An intelligent train linking Beijing to Zhangjiakou, North China's Hebei Province, will use the new speed train, a Chinese official said on Tuesday.

This marks the first driverless high-speed train in the world which can run above a maximum speed of 350 kilometers an hour, said Bayin Zhaolu, an official of Northeast China's Jilin Province, at a press briefing of the State Council, China's cabinet, on Tuesday.

The train, developed by local companies in Jilin, will adopt China's own BeiDou Satellite Navigation System for the first time and has "impressive functions" in intelligent driving, intelligent service and intelligence maintenance, Bayin said. The train is expected to have the capacity to begin mass production at the end of the year.

Local companies in Jilin are also developing a new generation of subways which use international leading unmanned operating systems, Bayin disclosed. "The subway train, made by carbon fiber, could automatically complete self-inspection, dispatching, driving, stopping, pulling back and self-washing," he noted.

The windows installed in the train operate a touch-screen display system that will allow passengers to watch television and send texts and picture messages, according to Bayin.

Steady progress has been made in the complicated construction of the Lhasa-Nyingchi Railway – a high-elevation railway in southwest China's Tibet Autonomous Region.

By Monday, construction started on the fourth station on the railway linking the regional capital city of Lhasa and Nyingchi some 400 kilometers away.

The line will have 34 stations.

So far, 90.3 kilometers of the 435 kilometers Lhasa-Nyingchi Railway has been completed.

The Lhasa-Nyingchi Railway is a section of the Sichuan-Tibet Railway, which will soon become the second railway to Tibet from the inland. Built in four sections – Lhasa to Nyingchi, Chengdu to Ya'an, Ya'an to Kangding, and Kangding to Nyingchi, the Sichuan-Tibet Railway is under busy construction. Once completed, it will shorten the time it takes to get from the inland to Lhasa to around seven to eight hours.

About 75 percent of the railway on the high plateau are bridges and tunnels, and it is expected to be completed in 2020.

In building the railway, the workers have to cope with challenges of hypoxia, the long rainy season, and complicated geological conditions.

"The workers have been braving safety risks as it is very easy for them to become tired after longtime intensive work in the oxygen-deficient environment. Also, wind can blow up to 62-74km/h in the dry, windy season in the Yajiang Valley along the Lhasa-Nyingchi Railway, which also poses risks to workers working at high positions," said Liu Jun, a Party official of the Lhasa-Nyingchi Railway Project of China Railway 11th Bureau Group.

by Railway-News
PUBLISHED: 03 Sep 2019

CRRC is developing a permanent magnet direct drive(as opposed to gearbox) electric locomotive. Its employees at the CARS National Railway Track Test Center have been putting this new locomotive through its paces.

CRRC’s Permanent Magnet Direct Drive Electric Locomotive
On 14 August CRRC engineers completed more than ten tests on the permanent magnet direct drive electric locomotive. For example, they tested static braking performance. The locomotive successfully passed this test – a good start for the overall type test of this kind of locomotive. And of course it was a good sign for the upcoming tests as well.

CRRC says its permanent magnet direct drive electric locomotive for passenger operations is a breakthrough in the field of AC electric locomotives. Previous Chinese innovations include the fast passenger electric locomotive and the heavy-duty electric locomotive.

According to CRRC this direct drive locomotive exhibited an increase in efficiency of more than 3 percentage points. That equates to an electric energy saving of 200kWh per hour. In addition, this locomotive is relatively inexpensive to maintain, it is green and it is quiet.

Permanent magnet direct drive technology is an emerging technology and viewed as the next generation of driving technology, CRRC said. This is the first time this technology has been applied in high-power AC electric locomotives.

The total power of this locomotive is 7,200kW. It contains six sets of high-power permanent magnet synchronous traction motors. These increase the locomotive’s overall efficiency from 85 percent to 88 percent, which is significant.
