Will future high-speed trains use the same base plates as ordinary trains?

The base plates used in future high-speed trains and ordinary trains may not be exactly the same because they have different needs and characteristics.
High-speed trains need to withstand higher speeds and greater impact forces, so they have higher requirements for the strength, stiffness and stability of the bottom plate. In addition, the floors of high-speed trains need to be flatter to reduce air resistance and noise. Ordinary trains have relatively low requirements for the floor because their speed is low and the impact on the floor is small. The floor plates of ordinary trains may pay more attention to economy and durability to reduce maintenance costs and increase service life.
Therefore, future high-speed trains and ordinary trains may use different baseplate materials, structures and manufacturing processes to meet their respective needs and characteristics. At the same time, with the continuous advancement and application of technology, future baseboards may also use more advanced technologies and materials to improve performance and reduce costs. It is understood that the floor materials used in high-speed trains and ordinary trains are also different.
The baseplate of high-speed trains is usually made of aluminum alloy. Aluminum alloy has the characteristics of lightweight and high strength, which can meet the requirements of high-speed trains for floor materials. The aluminum alloy bottom plate can reduce the weight of the train, improve energy utilization, reduce energy consumption, and also reduce wear on the tracks and lines. The floor of ordinary trains is usually made of carbon steel. Carbon steel has good strength and corrosion resistance and can meet the requirements of ordinary railways for base plate materials. Carbon steel base plates are relatively low cost and easy to maintain, so they are widely used in ordinary railways. Of course, the selection of specific floor material needs to be comprehensively considered based on factors such as different models, different lines, and usage environments.
