Central Japan Railway Co. said its magnetic levitation bullet train reached 603 kilometers an hour (375 miles an hour) during its test run Tuesday, breaking the speed record it set last week.
The train was running on a test course in Yamanashi prefecture in central Japan, and reached the record speed while passing through a tunnel. It exceeded 600 kilometers per hour for about 11 seconds, and hit 603 kilometers per hour at 10:48 a.m., the company said.
A spokesman at the company, known as JR Central, said it will apply to have the achievement listed in the Guinness World Records.
The previous record was set Thursday during a similar test, with the train reaching 590 kilometers an hour. JR Central said Tuesday’s run concludes the speed test of the maglev train, which was conducted to check the performance of the cars.
The maglev bullet train service is scheduled to open for business in 2027, but JR Central says the trains will operate at a maximum speed of about 500 kilometers per hour when it does.
During his visit to the U.S., which begins April 26, Prime Minister Shinzo Abe is set to pitch the new technology to the American market, including for a Washington-New York train link.
