China plans to expand high-speed network to 50 000 km
By 2025, the length of the mainline network will also reach 165 000 km.
This is reported by the railway magazine Railway Supply with reference to railjournal.
China’s State Council announced plans to expand the country’s high-speed network to 50 000 km by 2025, up from 38 000 km at the end of 2020, bringing the total network length to 165 000 km, up 19 000 km from 2020 .
New high-speed lines to be built:
- Beijing – Xiongang – Shangqiu
- Baotou – Yinchuan
- Xiangyang – Changde
- Tianjin – Xinyi
- Xi’an – Chongqing
- Xi’an — Shiyan
- Changsha – Ganzhou
- Xiongang – Xinzhou
- Taiyuan – Suide
- Yan’an – Yulin – Ordos
- Changchun – Tonghua
- Dunhua – Mudanjiang
- Harbin – Tieli
- Shanghai – Zhapu – Hangzhou
- Ningbo – Taizhou – Wenzhou – Fuzhou
- Jiaozuo – Luoyang – Pingdingshan
- Fuyang – Huanggang
- Yian – Laudi
- Tongren – Jishou
- Shaoyang – Yongzhou
- Nanchang – Jiujiang and
- Zhanjiang — Haiyan.
The five-year plan also includes a railway technological innovation plan that outlines a number of achievements and planned advances.
This includes expanding the use of Fuxing standard electric trains, a breakthrough in the development of 400 km/h passenger trains under China’s CR450 innovation, the development of 30 000-ton heavy-duty trains and high-speed freight trains operating at 160 km/h or more.
The intercity and urban rail fleet will also become lighter, smarter and more energy efficient as work continues on the 600 km/h Maglev and research on Hyperloop systems.
The plan also highlights the transition to lighter technology, the demonstration of stand-alone construction and maintenance equipment, and the development of new bridge systems, including a box girder system for high-speed rail.
There are also plans to develop the China Train Control System (CTCS) and establish a research and testing platform for electromagnetic environmental impact.
Research is also underway to develop a full range of railway design and construction technologies, including tunnels over 30 km long through areas of complex geology and long-span bridges across deep gorges.
To improve the work, studies will be carried out to reduce traffic intervals on high-speed lines, improve intermodal passenger transportation systems and technologies for passenger and freight transportation.
Passenger and cargo online portals will be modernized, and intelligent control and monitoring systems will be developed for large marshalling yards.
Plans for the development of the intelligent railway include:
- implementation of the smart railway 2.0 project on one of the Chengdu-Chongqing high-speed lines
- promotion of 5G technologies
- development of a demonstration project that will use Beidou satellite technology (the Chinese equivalent of GPS)
- development of intelligent platforms for construction, signaling and traction power supply systems
- creation of a technological platform for automated driving
- creation of a single multimodal platform for the transportation of passengers and goods based on the use of big data.
Work on security systems will include the development of a new generation of high-speed inspection vehicles, a video surveillance and intelligence application system for high-speed lines, a railway safety cloud platform, disaster prevention and rescue systems in high-altitude and complex geological areas.
