World's largest-diameter high-speed rail shield tunneling machine resumes tunneling #coolchina

#China's self-developed "Linghang," the world's largest-diameter high-speed rail shield tunneling #machine, has resumed tunneling after 41 days of maintenance. With a 15.4-meter cutter head and a weight of 4,000 tonnes, it is being used to excavate the land section of the Chongtai Yangtze River Tunnel. This project is expected to set a new world record for ultra-long single tunneling and is scheduled for #completion by the end of 2026. 📺 Subscribe to our YouTube channel and stay updated with our latest analysis and interviews:👇 https://www.youtube.com/channel/UCgrNz-aDmcr2uuto8_DL2jg 👈 Download our APP on Apple Store (iOS): https://itunes.apple.com/us/app/cctvnews-app/id922456579?l=zh&ls=1&mt=8 Download our APP on Google Play (Android): https://play.google.com/store/apps/details?id=com.imib.cctv For more: https://news.cgtn.com/news/2026-09-09/World-s-largest-diameter-high-speed-rail-shield-tunneling-machine-resumes-tunneling-in-China-1QiWqNYX6Vi/p.html Most watched videos: Impossible Challenge: 30 seconds to count banknotes BLINDFOLDED https://www.youtube.com/watch?v=ZmP_Ybj-jws Impossible Challenge: Gymnastics Boy Arat Hosseini from Iran! https://www.youtube.com/watch?v=8sxX--U4c8w Impossible Challenge: How to calm babies in 5 seconds? https://www.youtube.com/watch?v=kR3q9sXM7WA
