[The "15th Five-Year Plan for Railway Science and Technology Innovation" is issued: Research and develop high-power, low-energy hybrid locomotives and more efficient and intelligent heavy-haul railway equipment] On October 12, the State Railway Administration issued the "15th Five-Year Plan for Railway Science and Technology Innovation". It pointed out that the upgrade of green intelligent equipment should be promoted. Develop high-power, low-energy hybrid locomotives and more efficient and intelligent heavy-haul railway equipment, and build a technical standard system for the international market. Develop a new generation of trucks, a series of freight equipment with a speed of 120 to 200 kilometers per hour, cold chain transport containers such as lightweight refrigerated boxes and lithium battery transport boxes, as well as new tank containers and other transport equipment, and develop gauge-adaptive railway trucks. Improve the intercity and urban (suburban) equipment and technology system, promote the upgrade of internal combustion multiple units with a speed of 120 to 160 kilometers per hour, develop centralized power multiple units with a speed of 200 to 250 kilometers per hour, and develop a new generation of passenger cars and tourist trains. Develop flexible multi-source access power supply systems, high-strength, high-conductivity and wear-resistant cables, and complete sets of intelligent and highly reliable traction power supply equipment to build a new green and intelligent power supply model. Accelerate the technological innovation and application of integrated train dispatching and general-speed train control systems.
