The speed of a "bullet train" (High-Speed Rail) varies by country and specific line, but most modern systems operate at commercial speeds between 300 km/h and 350 km/h (approximately 186 to 217 mph). In Japan, the famous Shinkansen typically travels at a top operating speed of 320 km/h (199 mph) on the Tohoku line, though the Tokaido line (Tokyo to Osaka) is slightly slower at 285 km/h due to its older track geometry. China currently holds the record for the fastest conventional high-speed rail in regular service, with the Fuxing Hao trains reaching speeds of 350 km/h (217 mph). To put this into perspective, at these speeds, a bullet train can cover the distance of a 4-hour car drive in just over an hour. Beyond conventional "wheel-on-rail" trains, Maglev (Magnetic Levitation) technology is even faster; the Shanghai Maglev reaches 430 km/h (267 mph) in daily service, and Japan's upcoming L0 Series Maglev has clocked a world-record test speed of 603 km/h (375 mph), though it is not yet in commercial use.
