As of early 2026, there are only seven operational maglev (magnetic levitation) train systems in the world providing regular passenger service. These are concentrated in East Asia: four in China (including the famous Shanghai Maglev), two in South Korea, and one in Japan (the Linimo line in Aichi). While the technology has been researched for over a century, the high cost of specialized "guideway" infrastructure and the difficulty of integrating with existing rail networks have limited its global adoption. China remains the leader in the field, currently testing "high-speed" prototypes capable of exceeding 600 km/h. Japan is also making significant progress with the Chuo Shinkansen project, which aims to connect Tokyo and Nagoya at speeds over 500 km/h, though its full commercial opening has faced various delays. For now, maglev remains a niche, high-tech solution for short-distance airport links or specialized urban transit rather than a replacement for traditional high-speed rail.
