Why can China's high-speed rail run so fast? The answer is simple: good tracks, good trains, and good operations! But after riding the high-speed rail for so many years, do you understand how the high-speed rail tracks are laid? Today, the editor will take you to see how a rapid railway channel with a designed speed of 350 kilometers per hour is paved.

The first step in laying track is to pull the rails. A rail with a length of 500 meters and a weight of 30 tons is pushed by a track-laying push vehicle at the rear and towed by a tractor in the front. Working in tandem and in tacit cooperation, they ensure the smooth progress of the rails.

On the track plate under the rail, such rollers are evenly placed every 5m to 10m to reduce friction and make the rail move forward smoothly as if it were stepping on a "skateboard".
After the long rail is laid in place, construction workers will use a press to jack up the rail and take out the roller below. At the same time, the rails will be locked and fixed with fasteners on the track plate.

How do two long rails become one when they meet? At the junction of the two rails, construction workers will use joint splints to temporarily connect the two long rails and wait for the final welding. In this way, a seamless rail is basically laid.

The track laying behind China's high-speed rail is not only a display of technology, but also the crystallization of wisdom. Every smooth ride is inseparable from these carefully laid tracks. Thumbs up for China's high-speed rail and the craftsmen behind it!
