A world-changing technology being incubated in Hong Kong promises to make rail travel safer for passengers.

The new innovation will detect cracks along the rail line with minimum interruptions to train schedules, according to Ni

As the world’s first-ever technology of its kind, the progress it has made means rail safety inspections can be completed from a central control room without the need for time-consuming onsite inspections and disruptions, Ni Yiqing, leader of the development team and a professor at Hong Kong Polytechnic University, told China Daily.

The new innovation will detect cracks along the rail line with minimum interruptions to train schedules, according to Ni. Rail operators are also able to monitor an entire rail network continuously and react immediately when problems occur, he said.

The technology applies ultrasonic guide waves through fiber optic cables, which Ni described as pioneering. “It’s (a matter of) knowing immediately which of 12 pairs of wheels on a train have cracked through wear and tear, or which rails have broken.”

As the technology enables problems to be detected early, it will improve comfort for riders, as well as punctuality.

The team is also innovating a new method of monitoring railway degradation. Other tasks include building devices capable of sensing, absorbing and harvesting electro-magnetic radiation and interference generated by electronic components in the monitoring systems.

The project will be carried out over the next four years by researchers from universities in Hong Kong, Chongqing and London.

The application is expected to be scalable for global high-speed rail networks of longer range and higher speed.

Its industrial partners include Hong Kong’s Mass Transit Railway Corporation, China Railway Corporation in Beijing and Singapore’s SMRT Corporation. The partners will provide test bed and help accelerate technology transfer.

“We hope the research can help to turn the traditional railway industry into one that’s modern and smart,” said Alex Wai Ping-kong, vice-president of PolyU.

Ni’s project was among 30 proposals awarded grants earlier this month under the Research Impact Fund -- the first group of grantees since the fund was set up by the HKSAR Government in May 2017.

The 30 proposals received a total of HK$193 million (US$24.6 million), more than 30 percent of which went to PolyU’s projects. Ni’s four-year research project got nearly HK$6 million, starting from June this year.

The 30 projects, with funding for three to five years, cover a wide range of fields such as research and development of drugs, innovative reclamation and building methods, and security and applications of the internet of things.

The fund was launched after Chief Executive Carrie Lam Cheng Yuet-ngor pledged in her 2017 Policy Address to double Hong Kong’s expenditure on research and development to 1.5 percent of GDP from 0.7 percent during her five-year term.

A couple of years ago when I was a sophomore student I traveled to Lijiang for the first time via a hard-seat train taking more than 8 hours.
Can't believe what has been happening in this region, the sheer speed of building railways, tunnels and expressways is mind-boggling.
NEXT: bullet trains from Lijiang further north to Shangri-La!

New high-speed rail links hot tourist attractions in Yunnan

A new high-speed railway linking some of the famous tourist attractions in southwest China's Yunnan Province made its first run on Saturday.

The bullet train left Kunming, the provincial capital, at 8:15 a.m., and arrived at Lijiang, a popular tourist city, three hours later.

It is the first time that Lijiang, a city well-known for its World Heritage old town, beautiful natural scenery and ethnic culture, is integrated into the nation's high-speed rail network.

Previously, the trip between Kunming and Lijiang took more than eight hours. Three pairs of bullet trains provide service between the two cities every day.

The new route, which has 10 stations, also connects to other hot tourist destinations in the province, such as the ancient town in Dali and the Three Parallel River area.

Xinjiang to invest over 10 bln yuan in railway projects
Source: Xinhua| 2019-02-15 13:56:30|Editor: Li Xia

URUMQI, Feb. 15 (Xinhua) -- Northwest China's Xinjiang Uygur Autonomous Region will spend more than 10 billion yuan (1.48 billion U.S. dollars) on railway construction this year, local authorities said Friday.

The investment will flow to major railway projects, including a rail line linking Hotan Prefecture with Ruoqiang County in the Mongolian Autonomous Prefecture of Bayingolin, according to the regional development and reform commission.

The construction of the Hotan-Ruoqiang railway began in December 2018 and will last three and a half years. The rail line is designed to be part of a railway network circling the Tarim Basin and a crucial passage linking Xinjiang with other inland Chinese regions.

Xinjiang's government work report released in January has vowed to improve the region's railway transportation in 2019, building new passages to the inland areas.

The administrative centers of all prefectures and 75 percent of county-level regions in Xinjiang will be connected by rail by 2020, according to Xinjiang's transport construction blueprint (2016-2030).
 
Chinese engineers achieve major breakthrough in railway construction

Published on Feb 18, 2019

Chinese engineers in south China's Guangdong Province Sunday succeeded in cracking a hard nut problem in building the Foshan-Dongguan intercity railway by digging a railway tunnel just 5.6 meters below an existing busy underground railway line. The construction is set to be completed by 2020, which will be of great significance to the construction of the One-Hour Urban Economic Sphere in the Guangdong-Hong Kong-Macao Greater Bay Area.

China develops conceptual model of double-decker high-speed train

The Chinese Academy of Sciences has developed a conceptual model for future Chinese double-decker high-speed trains, which is likely to be able to run at speeds as high as 350 kilometers per hour (kph), official WeChat account of Science and Technology Daily reported on Feb.19.

The conceptual model of future double-decker high-speed trains in China has caught widespread attention in the country after it was revealed by media this past Monday.

The double-decker high-speed train technology is aimed at improving the passenger capacity, carrying capacity, and the economic efficiency of high-speed trains, according to Zhang Weihua, a professor of Southwest Jiaotong University, one of China’s top universities.

“As long as we can find solutions to such problems as low center of gravity and high capacity in design and technology, the double-decker high-speed train can probably guarantee speeds as high as 350 kph just as the single-decker high-speed trains do,” said Zhang in an interview with Science and Technology Daily.

The critical problem of the train’s potential loss of stability caused by the centrifugal force when the train, with a much higher standing train body and heavier load than a single-decker train, takes curves at high speeds. This has been regarded as crucial in the development of the double-decker train.

Zhang explained that so long as the double-decker train has a low center of gravity, when it runs at the specified equilibrium velocity, the centrifugal force and the transverse component of the gravity caused by super elevation will cancel out, which will make the train not only safe, but safer.

As to the problem of how to realize low gravity center and high capacity of the train, Zhang said that Germany’s next generation high-speed train developers hope to achieve good double-deck space in the train by materializing low floor with the help of independent rotating wheel technology.

Besides, the technologies concerning the overall design of the train body, including the arrangement of compartments and seats (or sleeping berths) are also important to the development of the new train.
