A new fleet of Fuxing bullet trains made their debut on Monday at the China National Railway Test Center in Beijing.

The trains, which are 440 meters long and can seat 1,283 passengers, are the longest high-speed trains in China.

With a maximum speed of 350 kilometers per hour, the trains will be deployed on the Beijing-Shanghai railway next month.

Two other Fuxing trains running at maximum speeds of 250 km/h and 160 km/h will also be deployed on the network. The slower version will replace older trains next month.

Zhang Bo, a researcher at the center, said the lower-speed Fuxing trains aim to provide a more comfortable travel experience for passengers
