China sends an empty train to check the tracks
HERE’S THE INTERESTING PART
When your trains go 200 miles per hour, hitting a stray branch isn't a minor bump, it's a catastrophe. To avoid turning their ultra-modern locomotives into high-speed shrapnel, Chinese rail operators send out a 'pathfinder' train with zero passengers every single morning. It absorbs any potential track hazards so the paying customers don't have to experience the thrill of sudden, violent deceleration.
One discovery leads to another.
