What's the difference between high-speed rail and motor vehicles, do you know?

Is the high-speed railway an EMU? Is the EMU a high-speed railway? What is the difference between high-speed rail and motor vehicles? Which is fast, high-speed rail or motor train? Which is expensive, an EMU or a high-speed railway? This question is often raised by everyone. Today, the editorial of the railway network will systematically summarize the differences between the high-speed rail and the high-speed rail, and see what the difference is between the high-speed rail and the high-speed rail.

The full name of high-speed railway is "high-speed railway", referring to the road, or "road + car" as a whole system.

The full name of EMU is "EMU train", referring to the car.

The "D" train, which is called "EMU passenger train", can be referred to as "EMU".

The G-head train, full name is "high-speed EMU passenger train", abbreviated as "high-speed railway" is wrong, the correct abbreviation should be "high-speed EMU" or "high-speed train".

& nbsp;

High-speed rail mainly refers to railways whose maximum operating speed is greater than (200,250,300 depending on different standards), mainly the speed attributes of railways; Multiple Units (MU) literally refers to the combination of several vehicles with dispersed or concentrated power. The 8-car EMUs operating in China are mainly 6-drive 2-drive and 4-drive 4-drive 2-drive. EMU is mainly the category of locomotive and rolling stock on railways. The relationship between them is that due to the need of speed, almost all of China's high-speed railways operate various types of EMUs, but EMUs do not necessarily run on high-speed railways.

The difference between
high-speed railway and motor vehicle: In the current passenger transport system of high-speed and inter-city railway in China, the main difference between motor vehicle (D-headed train) and high-speed railway (G-headed train) is that the motor vehicle (D-headed train) mainly runs on the existing speed-increasing line or inter-city railway, while the motor vehicle (D-headed train) runs on the trunk line of high-speed railway. Vehicles run slower or stop more than high-speed trains (G-shaped trains). In fact, the two definitions of high-speed rail and motor vehicle are not at all one level. High-speed railway refers to high-speed railway, which is the type of railway system described from the angle of speed; while electric train refers to a train with power in its carriage, and every carriage except the head can (be noted whether it is necessary or not) have power; but these two terms have been redefined on domestic railways, in fact, the carriages used on domestic high-speed railway are self-contained. The body is also an EMU, so it is right to be called an EMU.

In international standards, high-speed railways are those with speeds of over 200 KM per hour and up to 250 KM per hour under construction. The definition of a motor train is that there are power devices in multiple carriages, which constitute a train called a motor train. In China, the definition is slightly different. An EMU is a train with a speed of 200 to 300 KM per hour. The train number starts with D ("moving" alphabet); a high-speed railway is a train with a speed of more than 300 KM per hour, and a train number starts with G ("high" alphabet alphabet). At present, the trains running on China's high-speed railway are all EMUs, one group has 8 carriages, one train has one or two groups of EMUs (that is, one train can only consist of 8 or 16 carriages), and one group of EMUs, which can be 6-wheeled 2-wheeled, 6-wheeled, the other 2-wheeled, 4-wheeled and 4-wheeled. Motivation, the other four sections are not; it can also be 8 sections all have motivation. For long trains (16 compartments), the above configuration scheme is multiplied by two. Japan's high-speed railways operate EMUs, just like China's; but in Europe, especially in Germany and France, there are traditional trains on their high-speed railways. Both German ICE and French TGV have trains with powerless carriages towed by locomotives, but their speeds exceed 200 km/h, so it is not necessarily running on high-speed railways. They are all EMUs. Therefore, in international standards, high-speed rail refers to railways, and EMUs are a form of train. In our definition of China, high-speed rail and motor vehicles are railway systems that include both trains and railways. The difference lies in the different speeds per hour.

What is the high-speed railway?

High-speed railway generally refers to the type of railway transportation whose speed is more than 200 kilometers, most of which refers to passenger transport.

What is the EMU?

EMU is a group of trains consisting of powered trains (EMUs) and unpowered vehicles (trailers), which run in a fixed formation throughout the normal life cycle and can not change the formation at will.

EMUs are divided into diesel EMUs and electric EMUs according to their power types.

According to the power configuration, EMU can be divided into:

Power centralized type: refers to the whole vehicle power concentrated on one or both ends of the EMU vehicle, the rest of the intermediate vehicle without power (that is, trailer), similar to the conventional sense of locomotive traction of a number of vehicles.

Power Distribution: refers to the distribution of the whole power to a number of EMU vehicles, the intermediate vehicles have power (that is, EMUs), there are no power (that is, trailers), but also all vehicles can be powered.

Is the EMU a high-speed railway? The high-speed railway uses the EMU itself. In China, the EMU running at speeds above 300 per hour is called the high-speed railway, i.e. the high-speed railway. At present, the Chinese EMU has CRH1 CRH2 CRH3 CRH5, while the high-speed EMU is CRH2C CRH3.

CRH1 electric multiple unit is the CRH series ordered by the Ministry of Railway of the People's Republic of China from 2004 to Bombardier Transport and Qingdao Sifang Bombardier Railway Transport Equipment Co., Ltd. (formerly known as "Qingdao Sifang Bombardier Railway Transport Equipment Co., Ltd.", BSP) in order to speed up the Chinese railway for the sixth time. One of the models of high-speed electric multiple units. The Ministry of Railways of China has named all CRH vehicles imported from abroad as "Harmony".

D start train is EMU, G start train is EMU train. The representation of train number is DX (X is one or two or three or four digits). The standard pronunciation of railway system is "X times of train". D is the first letter of Chinese Pinyin of Chinese character "moving". EMU is composed of several self-powered vehicles and several non-powered vehicles. The powered vehicles are called EMUs and the non-powered vehicles are called trailers. The name of EMU used in China now is "Harmony Number". The English abbreviation is CRH, and the full name is China Railways High-speed (China Railway High-speed). There are 12 models of CRH1A, CRH1B, CRH1E, CRH2A, CRH2B, CRH2C, CRH2E, CRH3C, CRH5A, CRH380A, CRH380B and CRH6. These models introduce advanced technology from Canada, Japan, Germany, France and other countries, digest, absorb and localize, and become series products of EMUs with independent intellectual property rights in China. High-speed EMU train. The expression of train number is GXXXX (XXXX is four digits), the standard pronunciation of railway system is "Gao XXXX times", and G is the first letter of Chinese phonetic alphabet of "Gao". On December 26, 2009, China's first high-speed railway, the Wuhan-Guangzhou High-speed Railway, was officially opened and operated with a designed speed of 350 kilometers per hour and a maximum speed of 380 kilometers per hour.
