Japan's maglev train has broken its own speed record. Operator JR Central said that the fastest passenger train in the world reached 375 miles per hour in a test run on Tuesday. In 2003, it had set a record of 361 mph.

The train has traveled for just over a mile at a speed of exceeding 373 mph. The Maglev Test Line, near Mount Fuji about 50 miles west of Tokyo, is in a development phase. This technology will be used on a future 250-mile link that will reduce the travel time between Tokyo and Osaka to just over an hour. Currently, it takes minimum around three hours by bullet train.

Across the world, Japan's high-speed rail services are considered the most advanced. Every day, hundreds of trains run. Now, there is a difference between bullet trains and Maglev. The former ones run on steel rails and magnetic levitation trains hover above rails and are suspended by magnets.

The maglev trains started a project by Japan Airlines and the national railways with the government support. The project has undergone testing for decades. In 2014, construction of the Tokyo-Osaka link is expected to cost more than $76 billion.

The line is due to begin operations in the late 2020s. Similar system is operating in Shanghai that will link its airport to the city's subway system.
