BEIJING, Nov. 25 -- China has independently created core components of a high speed train, a breakthrough in the effort to make manufacturing of this type of train fully Chinese.

China CNR Corporation (CNR) said on Tuesday that the company has successfully produced two core components, a traction electric driver and a network control system, through independent research and development.

The company's CRH5A train model equipped with the two parts will soon finish its 5,000 km-test, the last testing stage, in north China's Harbin, CNR said.
