Is the high-speed rail Harmony a concept?

Is not a concept, the content of each concept is as follows:

1, bullet train:

Motor train and full-name power vehicle refer to vehicles equipped with power devices in rail transit system, including locomotives and power cars. Motor vehicles are equipped with driving wheels, and the corresponding vehicles without driving devices are trailers. If the train can run normally on the track, there must be a moving car to provide enough traction for the whole train, but it is not necessary to hang a trailer without power.

2. High-speed railway

High-speed railway, referred to as high-speed railway, refers to the railway with high standard of infrastructure design speed, safe and high-speed train running on the track, and the train running speed is above 200 km/h.

3. Harmony number

China Railway Department named all CRH EMU vehicles imported from abroad and jointly designed and produced as "Harmony". China Railway High-speed Railway is usually used to refer to CRH EMU trains that started after the sixth large-scale speed increase of China Railway Sixth Bureau on April 18, 2007.

CRH (China Railway High Speed) means "China High Speed Railway" in Chinese, which is the brand name established by China Railway Corporation for China's high-speed railway system.

China Railway High-speed Railway is an important achievement of China Railway's comprehensive implementation of independent innovation strategy, which indicates that the technical level of China's railway passenger transport equipment has reached the advanced level in the world, and therefore China has become one of the few countries in the world that can independently develop 380km/h EMU.

Extended data

Brief introduction of Code for Design of High-speed Railway;

Note: The high-speed rail in this document adopts the concept of high-speed rail in a narrow sense, which is a newly set level for the technical level of railway construction in China, referred to as high-speed rail level for short. Its comprehensive status is higher than that of the former national railway (similar to the relationship between expressway and first-class highway), and the design speed of railway infrastructure is only one aspect.

1. Passenger transport: High-speed rail lines only undertake passenger transport functions, and passenger and freight railways do not belong to technical high-speed railways.

2. Trunk line: The intercity railway is a branch line, which is built according to the content standard of Code for Design of Intercity Railway, and the high-speed rail standard is not adopted.

3. Speed: The design speed of the high-speed rail infrastructure ranges from 250km/h to 350km/h, and the initial running speed of the train is not less than 200 km/h. ..

4. Vehicles: The EMU with a speed of more than 200km/h shall be built, and the non-EMU trains and medium and low-speed EMU trains shall not run on the high-speed rail line.

5. System: CTCS-2 and above railway dispatching control system.

6. Track: High-speed rail lines are laid with standard heavy rails, while light rail, wide rail, narrow rail and maglev rail are not within the scope of high-speed rail lines.

7. Unit: It is managed and operated by China Railway Corporation and State Railway Administration (affiliated to 18 Railway Bureau Group Co., Ltd.), excluding urban rail transit.

8. New line: The high-speed rail construction standard is only applicable to the Beijing-Tianjin intercity railway in 2008 and the lines built later, and the existing railways before are not high-speed rail.

The new version of Code for Design of High-speed Railway was officially implemented on 20 15. Those that do not conform to the relevant provisions shall be built in accordance with other types of railway design specifications.
