China's rolling-stock maker CRRC announced on Friday that a variable configuration electric multiple unit (EMU) has passed all 60 routine tests and is ready for delivery.

Developed by CRRC Tangshan Co., Ltd, the variable configuration EMU is the first of its kind in the country, with a minimum formation unit of two powerheads and a maximum of 16 carriages.

Zhang Qinggang, lead designer of the project, said that the operation and maintenance of the current power-distributed EMUs can only be done to the entire train, since they have either 8 or 16 inseparable cars.

Described as the "Transformer" of EMUs, the variable configuration EMU can make flexible responses to the changes in passenger-flow and various demands of passengers.

The power car and trailer bodies can be freely combined depending on passenger flow and can operate at different speeds, as playing with Lego bricks.

The R&D team of the company has achieved technological breakthroughs in traction supply system integration, network control, and carriage coupling, according to Yang Cuizhi, executive manager of the project.

They also developed several new types of train cars by redesigning the equipments, functions and structures of EMUs.

Carrying capacity has increased by 50 percent, 33 percent, and 70 percent respectively for the newly-developed large-capacity longitudinal sleepers with berths on both sides, double-deck seat cars, and business cars.

Independent cargo compartments with insulated and reefer containers are added at lower decker of the dining cars and passenger-freight cars, which enables the train to transport goods.

With an intelligent network control system, passengers can enjoy full Wi-Fi coverage on the train, smart food ordering and luggage storage.

The company has applied nearly 80 patents for the variable configuration EMU, which has won the China Excellent Industrial Design (CEID) gold award and the Design Intelligence Award in 2018.

Headquartered in Beijing, CRRC is the world's largest supplier of rail transit equipment with operations in 104 countries and regions around the world.

China's first high-speed rail with an undersea segment connecting Zhoushan Islands in East China's Zhejiang province with the mainland began rolling with the launch of a full-scale survey and design, Xinhua News Agency reported on Tuesday.

The Ningbo-Zhoushan railway, a total distance of 77 kilometers, will run through a 16.2-kilometer-long undersea tunnel from Ningbo to Jintang Island in Zhoushan, and over several sea-crossing bridges when it encounters sea waters.

The railway is set to be a rail-road project which will facilitate high-speed trains as well as vehicles. In this project, trains and vehicles would travel across the sea via two separate tunnels.

Notably, the undersea tunnel at a length of 16.2 kilometers will boast the world's longest undersea high-speed railway tunnel when it is completed.

Different from the 6.7-kilometer-long immersed underwater tunnel of Hong Kong-Zhuhai-Macao Bridge, this underwater passage would be a shield tunnel and placed deeper in the seawater, which would create multiple difficulties for the construction crew.

According to Zhang Chaoyong, the railway's chief designer, the Ningbo-Zhoushan railway will support trains operating at 250 km/h.

When it is completed, it will shorten the travel time between Ningbo to Zhoushan to 30 minutes and to one hour and 20 minutes between Hangzhou, capital of Zhejiang province, to Zhoushan.

"The construction of this railway will bring China's ability to design bridges and tunnels to a new level," Zhang added.

The Chengdu-Kunming railway reconstruction project that passes through one of the most difficult terrains in the world finished track laying from Yongren to Guangtong county, in Southwest China's Yunnan Province, on Tuesday, according to Chinese Railways' WeChat account on Wednesday.

The Yongren-Guangtong section is planned to be put in operation later in 2019, and the whole railway project is planned to be finished in 2022.

The new Chengdu-Kunming railway will cut the travel time between the two cities from 20 hours to seven, and will serve as both passenger and freight lines to meet increasing needs that have emerged with local economic development.

The reconstruction project has high technical requirements due to the difficult geological conditions between the two cities. A tunnel named Mintai in Yunnan Province, which is part of the new project, passes through six shattered fault zones and five water-abundant areas. The project has to meet challenges including projecting mud soil, collapse, and rock deformations.

After the new Chengdu-Kunming railway goes into operation, the original one, which has been in operation since 1970, will mainly be used for freight transportation and short-distance passenger transportation.

China's top aircraft engineer calls for accelerated development of maglev trains
Source:Global Times Published: 2019/3/12 12:04:20

The chief designer of China's first homegrown passenger jet, the C919, has called for accelerated development of maglev trains to further increase the speed of the country's high-speed rail network and stay ahead of global competition.

Wu Guanghui, the vice president of Commercial Aircraft Corporation of China and chief designer of the C919, said at a recent discussion that maglev trains are necessary to further increase the speed of the rail network.

"The maximum speed for trains running on tracks is said to be 400 kilometers per hour and if we were to further increase speed, we must use magnetic levitation," Wu, who is also a deputy of the National People's Congress (NPC), said during a group discussion of deputies from Shanghai on Sunday, the Economic Daily newspaper reported.

China has already built a test line for maglev trains in Shanghai, which is capable of running at a speed of 500 kilometers per hour, but so far it has only been tested at a speed of 300 kilometers per hour, Wu said.

Wu, who has been involved in national research and development efforts in maglev trains, said others such as Japan and US electric car maker Tesla Inc have also planned to build maglev trains or expressed interest to do so.

"In fact, the whole world has now restarted conducting research on magnetic levitation," he said, suggesting that China should use maglev trains for travel between Beijing and Shanghai.

Asked whether such a move would impact the sale of the C919, Wu said "we are going on different paths! There are other paths for aviation."

China is accelerating its efforts on developing a national-level innovation center for high-speed trains in Qingdao, East China's Shandong province, aiming to be a global leading innovation force, officials said on Monday.

The establishment of innovation centers on a national level is a top-level decision, and the first one is focusing on rail transportation, as the rapid development of high-speed trains has become a new focus for China's high-end manufacturing sectors, said Zhao Minghua, deputy director of National Innovation Center of High-Speed Rail.

With an estimated investment of 60 billion yuan ($8.94 billion) and taking an area of six square kilometers, the center is expected to be completed in 2030. Construction of the center, by China Railway Rolling Stock Corp or CRRC, the world's largest railway vehicle manufacturer by sales revenue, and Qingdao municipal government, began last February.

"One of its goals is to focus on cutting-edge technologies and explore future visions in the high-speed train industry, helping China take the leading role in the sector," said Zhao, adding that the center will mainly feature high-end R&D, commercialization and city-industry integration.

"The center also encourages international cooperation and involves technology transfer as well as certification work," added Zhao.

According to Ji Zheng, one of the center's construction managers, three major programs are under construction, including two labs for high-speed maglev trains, which are expected to come into use in October.

"Design and research of 600 km/h maglev trains is expected to take place at the center," said Ji.

Ji said that the core part of the center will be functioning in 2021, with 16 programs worth 30 billion yuan, including a key national lab.

Qingdao, home to CRRC Sifang and Bombardier, is now enjoying robust growth in the high-speed train manufacturing sector.

Around 65 percent of China's EMU trains set off on their first trip from Qingdao and 25 percent of the subway trains running across China have been produced there.

Fuxing bullet trains, representing China's latest self-developed new-generation bullet trains, have been developed in Qingdao.

A demonstration zone on rail transportation sectors was established in the city's northern Chengyang district four months ago.

Last year, the output value of the area's rail transportation industry chain reached 85 billion yuan, becoming one of the pillar industries in the city.

Construction of Hainan-Guangdong railway to start in 2019


2019-03-19 13:50:01 Global Times Editor : Li Yan

South China's Hainan Province plans to build a rail link with South China's Guangdong Province, which a Chinese analyst said will provide opportunities for economic development for cities along the line.

The railway is to connect Haikou, the capital of Hainan, and Zhanjiang, Guangdong, according to a report by local newspaper Haikou Daily over the weekend.

The line can significantly improve communication between Hainan and other provinces.

According to the report, an evaluation committee set up by China Railway Co met from January 14-18 for a feasibility study. Xie Jing, manager of the Hainan Development Holdings Co as well as a member of the National Committee of the 13th Chinese People's Political Consultative Conference, said during this year's two sessions that the feasibility study report is being compiled, and the project should not run into any obstacles in terms of technology.

According to a report by soho.com, the railway is about 130 kilometers long and will cost 14.4 billion yuan ($2.15 billion)

Previously, the only means of getting to and from Hainan were planes and ferries, which are costly and highly susceptible to weather conditions.

The province experiences of heavy passenger volume, especially at some times of the year. According to a report by chinanews.com in March, during this year's Spring Festival holidays, up to 10.36 million people traveled to and from the island, but flights were suspended 10 times due to heavy fog.

Similar conditions occurred during last year's spring festival, when foggy weather that lasted seven days led to thousands of passengers and vehicles being held up at the ports.

Zhao Jian, an expert on the railway industry at Beijing Jiaotong University, told the Global Times that the new line will ease the pressure on ferries and planes. It will also help develop cities along the line, which can enjoy a synergy effect created by the transportation network being built up in the Hong Kong-Guangdong-Macao Greater Bay Area.

"Similar to the railway along the Hong Kong-Guangdong-Macao Greater Bay Area, the most important aspect of the new railway is to connect major cities and facilitate communication and economic development," Zhao said.

For Hainan, the railway can also decrease the cost of freight transport and make it more convenient, he said, meaning smoother transportation and movement of goods and people, which is vital to economic development.

The railway's construction still faces challenges concerning collaboration among multiple departments, including different administrations from different provinces, Xie was quoted as saying in the Haikou Daily report.

Zhao also mentioned some challenges the railway may face in terms of operation.

"Unlike the Hong Kong-Guangdong-Macao Greater Bay Area, the economy around Hainan is not as robust, which means the market is not as mature and it will be costly for the local government to run the railway," Zhao told the Global Times.

"That's especially so because the number of passengers travelling in and out of the island can vary greatly depending on the season. Most visitors go to Hainan during the winter. This, too, can pose some challenges to the railway's operation and maintenance."

China developing world's first 350 km/h automated bullet trains

China Plus, January 4, 2019

China Railway Corporation is developing a train control system that will allow Fuxing bullet trains to operate automatically at speeds of up to 350 kilometers per hour, reports Science and Technology Daily.

The national railway operator said on Tuesday that the automatic train operation (ATO) system will first be used on trains running between Beijing and Zhangjiangkou in Hebei Province. The automated trains will go into service in 2022 ahead of the opening of the Winter Olympics.

The ATO system will free train drivers from tasks such as stopping the train at stations and opening and closing passenger doors. The system will speed up or slow down a train according to the running schedule.

The ATO system is already installed on some high-speed trains on two 200 kilometer an hour lines in Guangdong Province. This was the first time anywhere in the world that ATO equipment was used on trains running at such a high speed.

Late last year, China Railway Corporation carried out a three-month field test of the ATO system on a high-speed train running between Beijing and the city of Shenyang in Liaoning Province. Experts said the system passed all of its tests and was ready to be put into regular use.

http://www.china.org.cn/business/2019-01/04/content_74339944.htm
I would like very much to take the 350 km/h automated bullet trains,
i took China high speed railway oftenly and never encountered any problems.
In China, if you want to take the high-speed rail, you must arrive at the high-speed rail station in advance, and the high-speed train will start on time and will not wait for anyone.

I am more interested in the 650 km/h operation speed of new generation bullet train and near future 1000km/h to 3000 km/h vacuum tube high speed rail.
