A Japanese maglev which is the fastest passenger train in the world has broken its own speed record.

Operator JR Central said the train reached 375mph (603kph) in a test run today, surpassing its previous record of 361mph (581kph) set in 2003.

The train travelled for just over a mile (1.8km) at a speed exceeding 373mph (600kph).

Japan's high-speed rail services are among the most advanced in the world, with hundreds of trains running each day with minimal delays.

The Maglev Test Line, near Mount Fuji, about 50 miles (80km) west of Tokyo, is developing technology for use on a future link between Tokyo and Osaka. The magnetic levitation trains hover above rails, suspended by powerful magnets.
