To promote the high-quality development of passenger transportation and fully meet the diversified transportation needs of passengers, it is necessary to enrich passenger transportation products. As the wheeled rail mode of transportation has basically reached a speed bottleneck, the study proposes that the high-speed magnetic levitation railway with a speed of 600 km per hour be involved in passenger transportation as a new transportation product. Comparing the advantages of high-speed maglev trains in terms of speed, safety, and economy with those of high-speed railway, airlines, and other modes of transportation, the study calculates the sharing rate of high-speed maglev trains in the transportation market, researches the induced incremental capacity generated by the new mode of transportation, and obtains the capacity of maglev railway on different routes. Research results show that 600 km/h Maglev train is the most competitive Maglev speed, with an advantageous distance between [500, 3000] kilometers. To realize medium and long-distance passenger transportation between the core cities of China's 4-pole urban agglomeration, Beijing-Shanghai, Beijing-Guangzhou and other trunk line corridors and point-to-point high-speed magnetic levitation trains will become the priority development direction.
