China plans to expand high-speed train network to 50,000 km by 2025

Beijing, China (Urban Transportation News): China’s State Council has announced plans to expand the country’s high-speed train network to 50,000 km by 2025, up from 38,000 km at the end of 2020, with the total network reaching 165,000 km, an increase 19,000 km compared to 2020. The plans were included in the 14th five-year plan, which covers all modes of transport.

According to the plan, a total of 22 new high-speed railway lines will be built, namely Beijing – Xiongan – Shangqiu HSR; Baotou – Yinchuan high-speed line; Xiangyang-Changde HSL; Tianjin – Xinyi high-speed line; Xi’an – Chongqing high-speed line; Xi’an-Shiyan HSR; Changsha – Ganzhou high-speed train; Xiongan – Xinzhou high-speed line; Taiyuan – Sweden HSR; Yan’an-Yulin-Ordos HSR; Changchun-Tonghua high-speed line; Dunhua-Mudanjiang HSR; Harbin-Tieli HSL; Shanghai-Zhapu-Hangzhou HSL; Ningbo-Taizhou-Wenzhou-Fuzhou HSL; Jiaozuo – Luoyang – Pingdingshan high-speed line; Fuyang-Huanggang HSL; Yiyang–Loudi HSR; Tongren–Jishou HSR; Shaoyang – Yongzhou high-speed line; Nanchang – Jiujiang HSR and Zhanjiang – Haian HSR.

New conventional lines include a second line connecting Liuzhou to Guangzhou, as well as Ruijin – Meizhou, Wenzhou – Wuyishan – Ji’an, Dingxi – Pingliang – Qingyang, Taizicheng – Xilinhot, Xiantao – Honghu – Jianli, Taiyuan – Heshun, Dali lines – Panzhihua and Wubei – Zhundong lines. The plan also includes the improvement and reconstruction of the Fuyu–Jiagdaqi, Nanjing–Wuhu, Yaqueling–Yichang, Tianjin–Jixian, Wangqing–Tumen and Zhongwei–Pingliang lines.

The five-year plan also includes a rail technology innovation plan, which outlines a series of planned advances and achievements.

This includes increasing the use of Fuxing’s standard EMUs, breakthroughs in the development of 400 km/h passenger trains under China’s CR450 innovation, the development of 30,000-ton heavy-haul trains and higher-speed freight trains operating at 160 km/h or more. Intercity and city rail fleets will also be made lighter, smarter and more energy efficient, while work will continue on 600 km/h maglev and the exploration of hyperloop systems.

The plan also emphasizes shifting to lighter technologies, demonstrating autonomous construction and maintenance equipment and developing new bridge systems, including a box girder system for railways. high speed. It is also planned to upgrade the Chinese train control system (CTCS) and build a platform for research and testing of electromagnetic effects on the environment. Research is also underway to develop a comprehensive set of railway design and construction technologies including tunnels over 30 km through areas with complex geology and long-span bridges in deep gorges.

To improve operations, research will be undertaken to reduce high-speed line spacing and improve intermodal passenger transport systems and passenger and freight service technologies.

China also plans to develop a smart railway including:

  • the implementation of a smart railway 2.0 project on one of the Chengdu – Chongqing high-speed lines
  • promotion of 5G technologies
  • a demonstration project showcasing Beidou satellite technologies, the Chinese equivalent of GPS
  • the development of smart platforms for construction, signaling and communication, and traction power systems
  • an automated driving technology platform, and
  • a unique multimodal platform for passengers and freight based on the use of big-data.

Work on security systems will include the development of a new generation of higher-speed inspection vehicles, a video surveillance and intelligent analysis application system for high-speed lines, a cloud platform for railway safety, disaster prevention and rescue systems for high altitudes and difficult geological areas, and large-scale infrastructure operation and maintenance systems for specific environments such as plateaus, mountains and seabed.
