Harmony EMU, when was the Harmony EMU born?

At present, the EMU is divided into: CRH1, CRH2 and CRH3 are all produced by factories under China CNR Group and China CSR Group, and the specific production division is only known within the group, and it is difficult for outsiders to know.

More famous EMU manufacturers: Qingdao Sifang locomotive manufacturing ****, Tangshan rail locomotive ****.

At present, the maximum speed of the EMU is 394 kilometers per hour, which is the latest CRH3 operation, which generally does not exceed the fastest speed of the EMU when it is tested.

Call **Ask the Ministry of Railways ==

At present, there are four main types of high-speed rail locomotives in China: CRH1, CRH2, CRH3 and CRH5. The new "bullet" train runs 56 meters per second, and when it passes, it can set off a force 8 wind.

CRH1 is produced by Qingdao Sifang-Bombardier-Bauer Railway Transportation Equipment **** (referred to as BSP), and Sifang locomotive accounts for 50% of BSP's equity. CRH2 is a joint production of CSR Sifang and Kawasaki Heavy Industries and other Japanese foundations, using Japanese Shinkansen technology. CRH3 is produced by Tangshan Locomotive Factory and Siemens, using German technology.

The CRH5 is produced by Changchun Bus Factory and Alstom. Among them, CRH1, CRH2 and CRH5 are designed to reach a speed of more than 200 kilometers per hour, while CRH3 is designed to reach a speed of more than 300 kilometers per hour. Therefore, the sixth major speed increase will mainly use the first three main models, and it was these three main models that won the bid in the original bidding of the Ministry of Railways.

After losing in the first round, Germany's Siemens entered China's high-speed rail locomotive manufacturing in the second round. At present, China is the fifth country to produce EMUs after France, Japan, Canada and Germany. *)=*">

On December 22, 2007, the first domestically produced 300 kilometers per hour "Harmony" EMU train (CRH2-300) was completed and rolled off the assembly line in CSR Sifang Locomotive and Rolling Stock Co., Ltd.

On April 11, 2008, the first domestic CRH3 "Harmony" EMU with a speed of 350 kilometers per hour rolled off the assembly line of CNR Tangshan Rail Coach Co., Ltd.

Some. For example, the CRH3A dining car of the Xicheng passenger special train unit also has a special ordering system. The bullet train adopts 8 cars, that is, each group of trains has 8 carriages, including 1 first-class seat, 6 second-class seats, and 1 second-class restaurant car, with a capacity of 613 people.

Another example is CRH1B, numbered CRH1B-1041 CRH1B-1060. The 16-car train includes 10 bullet trains and 6 trailers (10m6t), including 3 first-class cars, 12 second-class cars, and 1 dining car. The maximum operating speed is 200-250km h, and the appearance of the car remains unchanged.

Harmony belongs to the electric EMU, in 2004 China introduced Germany, Japan and other countries of high-speed EMU technology, on the basis of digestion, absorption and re-innovation, the production of high-speed EMU series of general name.

The Harmony EMU is a major achievement of China's railway in the comprehensive implementation of the independent innovation strategy, marking that the technical level of China's railway passenger equipment has reached the world's advanced level, and China has become one of the few countries in the world that can independently develop a 380 km/h EMU.

In 2004, China introduced high-speed EMU technology from Germany, Japan and other countries, and on the basis of digestion, absorption and re-innovation, it produced the "Harmony" series of high-speed EMUs, which met the needs of the people in a relatively short period of time. Based on different platforms, the "Harmony" was developed.
