What is the fastest speed ever reached by a passenger train, measured in kilometers per hour?

The fastest speed ever reached by a passenger train, which is an impressive 581 kilometers per hour, was achieved by the Shinkansen's Maglev train in Japan during a test run. This groundbreaking achievement showcases advancements in train technology and engineering. The speed highlighted is significant not only for its record but also for the implications it has for future transportation systems, emphasizing the potential for rapid transit across long distances. The capabilities of magnetic levitation technology enable such extraordinary speeds, which traditional trains are unable to reach due to limitations in wheel-to-rail contact.

The other options reflect speeds that either exceed or do not align with the verified records for passenger trains, which helps highlight the remarkable nature of the 581 kph benchmark.
