A Japanese magnetic levitation train has now broken three different records.
The train first broke the world record back in 2003 when it made a top speed of 581km/h. Last week, it broke that 2003 record with a top speed of 590km/h.
In another test, near Mount Fuji in Japan, the train broke last week's record yet again, this time with a top speed of 603km/h.
The trains, which are called Maglev (Magnetic Levitation) Trains, use electronically charged magnets to lift and move carriages above the rail tracks.
Central Japan Railway (JR Central), which owns the trains, intends to introduce the service between Tokyo and the central city of Nagoya by 2027.
The 280km stretch between the two cities would only take 40minutes by then, which is less than half the current time.
Construction is expected to be close to $100 billion just for the stretch to Nagoya, with more than 80% of the route expected to go through costly tunnels.
Passengers on the train however, will not experience the trains record breaking speeds as the company has said it's train will only run at 505km/h.
The Japanese Government also hopes to sell the Maglev train technology overseas.
