Do high-speed trains and trains use tracks?

Both cars do not use tracks, as follows:

1. According to today's headline information query, high-speed rail generally uses ballastless track, and trains use ballasted track.

2. The gradient of the two tracks is different: the gradient of high-speed rail is about 20%, while that of ordinary express is only about 10%.

3. The steel used for the two tracks is different: 65 kg for high-speed rail and 60 kg for ordinary railway. The heavier the steel is, the higher the bearing capacity it can bear.

4. High-speed trains and trains have different requirements for land subsidence: there are also differences in route selection, and the requirements of high-speed trains for land subsidence are much higher than those of ordinary railways.
