Trains and moving trains do not run on one track.

1. Ballastless tracks are generally used for high-speed rails, and ballasted tracks are used for trains.

There are many large and small crushed stones in the middle of the train tracks that we usually see. This is called slag.

But for high-speed rail tracks, there is no such gravel. Instead, a whole slab is laid under the track. The purpose of this is simply to increase

the speed of high-speed rail running on the track.
2. The slopes of the two tracks are different.

The speed of ordinary express trains is generally below 120 yards per hour, and the highest speed will not exceed 150 yards per hour.

But for high-speed rail, the speed can reach 300 kilometers per hour, and the maximum speed can reach 520 kilometers per hour.

The slope of high-speed railways is generally about 20%, while the slope of railways for ordinary fast trains is generally only about 10%.

3. The steel materials used for the two tracks are different.

Under normal circumstances, the high-speed rail uses 65 kg, while the ordinary railway uses 60 kg. The weight of the steel used will increase the

bearing capacity.

4. High-speed rail cars and trains have different requirements for ground subsidence.

There are also differences in route selection. The requirements of ground subsidence for high-speed rail are much higher than those of ordinary
