The world's first virtual track train was unveiled on Friday in the city of Zhuzhou in central China's Hunan Province. 

 The train, which is 32 meters long and 3.4 meters high, can accommodate 307 passengers and has a top speed of 70 kilometers per hour. 

Instead of tracks, the train runs along white-dotted lines on the test ground, controlled by hundreds of sensors. The train also uses rubber tires, which makes the ride like riding the bus. 

Its lithium titanate battery enables the train to run 25 kilometers after just 10 minutes of charging.
