          Noting the challenge of achieving a lightweight design, considering both speed and energy efficiency, Wang Wenjing, a professor at the School of Mechanical, Electronic and Control Engineering of Beijing Jiaotong University, said that the university's team focused on reducing the weight of the load-bearing components.

          "Advanced materials like carbon fiber were also incorporated to reduce weight while maintaining strength, thereby ensuring safety and durability at high speeds," she noted.

          Sui Fusheng, a researcher at the Institute of Acoustics of the Chinese Academy of Sciences, highlighted the complexity of balancing weight reduction with noise control. The team developed integrated composite materials that provide both thermal insulation and soundproofing. This innovation reduced material costs and complexity while improving passenger comfort by adjusting temperature and controlling noise. Despite the challenges, the team's solutions have set the stage for quieter, more efficient high-speed rail travel.
