China's defunct railway ministry, which was replaced in part by China Railway Corp, launched the research and development for the Chinese-standard bullet trains in 2012 with engineers from 30 institutes and companies.

The trains now running on the country's high-speed rail network have been designed and built in accordance with various foreign standards.

This forces China Railway Corp to run a number of different support and maintenance programs for trains made to different specifications, keeping operating and support costs high. The lack of a Chinese-standard bullet train has also hampered the nation's efforts to export its rail technology and products.

Compared with in-service bullet trains, the new models feature longer service life-they can operate 30 years, while the existing ones can be used for 20 years. They also have streamlined designs that allow lower power consumption and more space for each passenger, said Zhang Bo, a designer from the China Academy of Railway Sciences.

He said the overall design and all of the key parts on the new bullet trains, such as traction, brake and control software, were developed solely by Chinese engineers.

He Huawu, chief engineer of China Railway Corp, said his company will gradually replace all in-service bullet trains with Chinese-standard types. "The move will greatly reduce our production, operational and maintenance costs, and will help us export our railway equipment, trains and technologies," he said.
