China Standard EMU, the symbol of China's standard EMU, marks the () of our country.

1. China Standard EMU

The China Standard EMU, also known as the CRH series in Chinese, is a series of EMU trains organized by China Railway Corporation, possessing complete independent intellectual property rights, and reaching advanced global levels. Its English code is CR, and it surpasses the CRH series in terms of quality.

2. The Significance of Harmony EMU

The Harmony EMU is a major achievement of China's comprehensive implementation of independent innovation strategies, signifying that China's railway passenger equipment has reached world-class levels. As a result, China has become one of the few countries capable of independently developing 380km/h EMU trains.

3. Dominance of Chinese Standards

The China Standard EMU refers to EMUs in which the Chinese standard system predominates (with Chinese standards accounting for 84% of the 254 key standards). Their functional and construction standards exceed European and Japanese standards, characterized by distinct Chinese features.

4. Advantages of Standardization

The standardization of components in China Standard EMUs allows for interchangeability, resulting in substantial cost savings. This innovation, a pioneer internationally, streamlines operations and maintenance processes.

5. Importance of Coupling

"Coupling" is a method aimed at increasing transport capacity. Normally, EMUs consist of 8 carriages. Coupling involves connecting two 8-carriage EMUs together to form a 16-carriage unit. This strategy enhances operational efficiency and capacity.

6. Independent Technological Advancements

The China Standard EMU project has achieved complete independent intellectual property rights and established a comprehensive, scientifically advanced high-speed EMU technical standard system, reaching global standards. The birth of the "China Standard EMU" ushers in a new era for China's railway equipment standards.

7. Milestones of "China Standard EMU"

CRH5 is a type of electric EMU, part of the CRH series, ordered by China Railway Ministry to implement the sixth major speed-up campaign. This collaboration with foreign expertise has significantly improved high-speed railway transport in China.
