[The "15th Five-Year Plan for Railway Science and Technology Innovation" is issued: Steady and orderly advancement of research on high-speed maglev technology with a speed of 600 kilometers per hour and the test verification of localized key technologies] On October 12, the State Railway Administration issued the "15th Five-Year Plan for Railway Science and Technology Innovation". It pointed out that engineering technology for higher-speed trains should be carried out. Carry out basic technical research on the wheel and rail wear patterns of trains running at 400 kilometers per hour, the changing trend of pantograph-to-net matching performance, and the impact of environment, lines and signals on vehicle operation, and establish and improve the technical system and maintenance system for high-speed rail vehicles to match each other with subsystems such as line bridges and tunnels, power supply, and communication signals. Carry out multi-objective matching iterative design of low resistance, low noise, low axle weight suitable for batch operation at a speed of 400 kilometers per hour, and form a series of CR450 EMU products. Research and establish an inspection and maintenance system for EMUs with a speed of 400 kilometers per hour. Promote research on high-speed maglev technology with a speed of 600 kilometers per hour and test verification of localized key technologies in a steady and orderly manner.
