Great news So remarkable that I just passed along the original Weibo copy plus the translated version in some local language

Some feedbacks I got from some pals, they still feel amazed for once took ride on Fuxing 350kph and now must imagine that one day in not-too-distant future they may probably have chance to feel the ride on 600kph or even higher frankly me too, I had chance to taste the 300kph ride twice from Beijing to Suzhou and from Taiyuan to Beijing, just one year prior to the Fuxing 复兴 era.

QINGDAO, June 21 (Xinhua) -- Performance checks of China's domestically-developed prototype magnetic-levitation train, with a designed top speed of 600 km per hour, began in Shanghai Sunday.

The testing prototype, which has only one car, can check and optimize the key technologies and core system components of the high-speed maglev system and lay a technological basis for the forthcoming engineering prototype, according to CRRC Qingdao Sifang Co., the train maker headquartered in eastern China's Shandong Province.

During Sunday's first trial-run on a maglev test line, more than 200 components, including working conditions of turnouts, small curves and ramps, were analyzed, the company said.

The prototype magnetic-levitation train was manufactured in the company's production line in the city of Qingdao, Shandong, in May.

Ding Sansan, head of the research and development team and deputy chief engineer of CRRC Qingdao Sifang Co., said that preliminarily checks have found the vehicle stable. "All key technical indexes met the design requirements and expectations," said Ding.

He said that high-speed maglev transportation is a coupling system of four major parts: vehicles, traction power system, operation control communication and line tracking. Through the prototype test, the interface relationship of a high-speed maglev system under dynamic conditions can be preliminarily verified, providing support for the verification and optimization of the system's performance and its core components.

The company said the research and development of a five-car engineering prototype of the high-speed maglev are going smoothly. It is scheduled to roll off the production line in 2020.

Maglev trains generate less noise due to the absence of wheel-rail friction. Besides, their minimum turning radius is only half that of a subway, allowing it to better bypass buildings in route planning.

China to Boost World's Biggest High-Speed Railway System by 2,300 km This Year​

(Yicai Global) July 17 -- China is expected to build 2,300 kilometers of high-speed railways this year, according to the state-owned operator of the world's largest network of high-speed railways.

Some 605 km has already been built during the first half, China Railway added. The country's total spending on train route construction should exceed CNY500 billion (USD71.4 billion) this year.

By the end of last year, China had formed a 35,000-km high-speed railway network, about 70 percent of the world's total. It began building the first such route between Beijing and Shanghai in 2008.

CHANGSHA, July 30 (Xinhua) -- China has developed a high-power electric locomotive, marking a major breakthrough in the country's railway technology.

On Wednesday, an electric locomotive with a single-unit power of 28,800 kW and a traction force of 2,280 kN rolled off the production line of CRRC Zhuzhou Locomotive Co., Ltd.

The locomotive was jointly developed by CRRC Zhuzhou and China Energy Investment Corporation. It is composed of six sections and is 106 meters long.

Dubbed "Shen-24", the locomotive has a maximum speed of 120 kph and can pull a 10,000-ton freight train on a 1.2 percent slope.

Merely increasing the number of power units can not achieve ultra-high power and ultra-high traction in locomotives, said Liu Youmei, an academician with the Chinese Academy of Engineering, adding that it requires a comprehensive innovation of the system.

The locomotive is not only more powerful but also smarter, safer and more environmental-friendly than previous models, said Wang Wei, a manager with CRRC Zhuzhou.

After delivery, the locomotive will run on Shenmu-Shuozhou Railway in coal-rich provinces of Shaanxi and Shanxi. The railway is one of the main energy-transportation arteries in the country.

The technical proposal for the Ningbo-Zhoushan Railway, China's first high-speed railway line with an undersea segment, has been completed, the Ningbo Evening News reported on Saturday.

After two years' preparation, the core technical proposal for the project's 16.2-kilometer-long undersea tunnel, the longest in the country, passed assessment by a panel of experts headed by Qian Qihu, an academician from the Chinese Academy of Engineering, on Thursday.

Connecting the Zhoushan Islands in Zhejiang province with the mainland, the 77-km Ningbo-Zhoushan railway line will run through the tunnel and over several bridges from Ningbo to Zhoushan via Jintang Island.

The project will allow high-speed trains and vehicles to travel across the sea via separate tunnels.

Unlike the 6.7-km immersed tube tunnel that is part of the Hong Kong-Zhuhai-Macao Bridge, the undersea tunnel on the Ningbo-Zhoushan railway line will be built using a shield and be deeper, creating multiple difficulties for the construction crew.

At a maximum optimal depth of 78 meters and with a diameter of 14 meters, the undersea tunnel's shield will be 10.87 km long upon completion, setting a new world record, according to Tang Xiongjun from China Railway Siyuan Survey and Design Group, who is in charge of the undersea tunnel project.

When it is completed, trains traveling at 250 km/h will be able to go from Ningbo to Zhoushan in just 30 minutes. Driving between the two places, made possible by a series of bridges, currently takes about three times as long.

Trains using the tunnel will be able to travel from Hangzhou, the capital of Zhejiang province, to Zhoushan in one hour and 20 minutes.

Officials said construction of the line is likely to start this year, with the project to take six to seven years to complete.

China is building the world's first high-speed train that can travel through a sea tunnel at a speed of 350 kilometers per hour in Shantou Bay, South China's Guangdong Province.

The 163-kilometer-long railway, which includes a 9,781-meter-long tunnel, has officially entered the substantive construction stage, with an investment estimated to be at 11 billion yuan ($1.6 billion), the China Central Television reported Tuesday.

According to the report, the tunnel will pass through 17 fault rupture zones in a magnitude-8 earthquake zone, of which eight are active faults, the first underwater tunnel of its kind anywhere in the world.

Most parts of the tunnel are located in high water pressure areas. As a result, construction personnel have to adopt measures to ensure that the tunnel structure is safe, waterproof and reliable, and that operating costs are controllable.

As the tunnel will be exposed to high-pressure seawater for a long time, its structure must be adapted to the strong corrosive environment while being able to withstand high water pressure penetration. The combined effect of the two factors makes the subsea tunnel environment more complicated.

Due to the tunnel's harsh environment, complex engineering geological and hydrogeological conditions, high construction risks and constraints of the construction period, workers will adopt a total of six construction methods in different sections.

After completion, the railway will connect major cities in Guangdong, such as Guangzhou, Huizhou, Shanwei and Shantou, and help accelerate the urbanization along the route, form a new high-speed rail economic belt and boost the revitalization and development of eastern Guangdong.

The project is part of a plan to narrow the development gap between eastern Guangdong and the Pearl River Delta region, and promote the balanced economic development of Guangdong.

Two maglev rail routes have been selected to be the pioneer in China's research on the high-speed maglev train system, according to the Chinese Academy of Engineering (CAE) on Wednesday.

The plan of two 600 kilometer per hour high-speed maglev routes, including the Shanghai-Hangzhou maglev, and the Guangzhou-Shenzhen maglev, have appeared on the presentation of He Huawu, academician and vice director of the CAE, during a conference on modern transportation engineering technology on Wednesday, the paper.cn reported.

The Shanghai-Hangzhou maglev will link Shanghai and Hangzhou in East China's Zhejiang Province, with a total length of 164 kilometers. It will also connect the current maglev line in Shanghai linking Pudong Airport.

The Guangzhou-Shenzhen maglev line will connect Guangzhou to Shenzhen in South China's Guangdong Province, with a total length of about 110 kilometers, and it is expected to be connected to Hong Kong's Kowloon station in the future.

The Shanghai-Hangzhou line will be mainly an open line, while the Guangzhou-Shenzhen maglev line will be an underground line, revealed He, who was one of major promoters of China's high-speed railway technology.

China's total high-speed rail mileage of more than 36,000 kilometers, ranks the longest in the world, and China's railway mileage had reached 141,400 kilometers, ranking second in the world at the end of July, according to data.

"While already having developed a modern high-speed rail network, it is necessary to develop a high-speed maglev system with a speed of 600 kilometers per hour. It will not only maintain China's advanced advantages in the field of high-speed rail, but also fill in the speed gap between high-speed rail and air transportation, thus forming a multi-dimensional transportation structure," He noted.
