What's the difference between a high - speed rail and an ordinary railroad track?
1, ordinary rail each section of 25 meters long, weighing about 1.5 tons, laying completed, the tracks will leave a gap between. In the process of running train, passengers at a distance will hear "Da Da" sound, this is the train to the crash of the welding point.2, high-speed rail line from a single length of 500 meters of rail laying, all of the ballastless track, the entire line level error of not more than 0.1 mm. While the train is moving at full speed, passengers will not hear "click".
1, the ordinary railway track is built on the basis of small stones piled up, and then the laying of sleepers or cement sleepers, which is called ballasted track.2, high-speed rail due to faster, generally use ballastless track, it uses slab bed or integral bed, there is no separate sleeper, relatively stable track, maintenance work is small, riding comfort higher.
The rails of the high speed rail are jointless and the track is free of debris.
