The title of the number one fastest operational train in the world belongs to the Shanghai Maglev in China, which utilizes magnetic levitation technology to achieve commercial operating speeds of up to 431 kilometers per hour. Meanwhile, in terms of steel-wheel high-speed railway systems, trains like the Chinese Fuxing Hao operate at regular speeds around 350 kilometers per hour. Japan is also actively developing its next-generation Chuo Shinkansen magnetic levitation train line, known as the L0 series, which has tested at breathtaking speeds exceeding 600 kilometers per hour, paving the future for ultra-rapid intercity transit.
