Imagine a high-speed train that never carries passengers, yet protects millions of them daily. Meet China's mysterious "Rail Doctor"—an advanced inspection system that works under cover of darkness to keep the world's largest high-speed rail network running safely.
🔍 Operating nightly, this uncrewed marvel uses lasers, AI, and 360-degree cameras to scan tracks with millimeter precision. It detects cracks, checks overhead wires, and even monitors surrounding slopes for landslides—all while zipping along at 160 km/h!
Why It Matters
🇨🇳 Safeguards 42,000+ km of high-speed tracks
🛠️ Can identify issues smaller than a grain of rice
🌙 Works when regular trains sleep (11 PM-4 AM)
"It's like giving the railways a full-body scan every night," says engineer Li Wei in an exclusive preview of the upcoming March 1 documentary. The system's LiDAR technology creates 3D maps so detailed, they could spot a loose bolt from space!
🚨 Mark your calendars: The full reveal drops this week! Get ready for never-before-seen footage of China's rail tech revolution.
