China Standard EMU refers to the EMU (the 254 important standards China standard accounts for 84%), which is dominated by the Chinese standard system. Its functional standards and supporting rail construction standards are higher than European standards and Japanese standards, with distinctive Chinese characteristics. . In the case of multiple CRHs (the four major types of introduction and China's self-designed CRH6), it is necessary to standardize (unify) the Chinese EMUs for interconnection. The standard EMU represents the current advanced standards system for the world of EMU technology. For the first time, the full autonomy of the EMU traction, braking and network control systems has been realized, which indicates that China has fully mastered the core technology of high-speed railways, and the high-speed EMU technology has achieved full autonomy. The standard EMU adopts the CR (China Railway) code, with three speed grades of CR400/300/200 and a continuous speed of 350, 250 and 160 km.

Key technical parameters

The important standards adopted by China's standard EMUs cover all 13 major aspects of EMU basics, bodywork, running gear, cab layout and equipment, and traction electrical.

The design of the standard EMU is combined with the actual needs of China, such as continuous high-speed operation, long distance, high density of driving, large passenger capacity, high cold, snowy, plateau sand, coastal hot and humid, haze, catkins and other conditions. , put forward the overall technical conditions of the EMU.
