A carbon fiber subway train of six carriages successfully completed its trial run in Qingdao, East China's Shandong province, on Wednesday.

Dubbed the "future subway train", it uses advanced technologies and new materials, according to its developer CRRC Qingdao Sifang Co.

The carriage body, bogie frame, driver's cabin and equipment compartment are made of carbon fiber composite materials, which make the train 13 percent lighter than traditional subway train, said Ding Sansan, deputy chief engineer of CRRC Qingdao Sifang Co. Silicon carbide inverter and permanent magnet synchronous motor are used in the hauling system, which save energy by 15 percent, said Ding.

The windows in the train are touch panels. Passengers can watch videos and news by touching the windows.
