Is there a difference between EMU and high speed rail ?

According to international practice, the speed of more than 200 kilometers per hour is called high-speed trains, in China, the earliest equipment of high-speed trains is the Guangzhou-Shenzhen line, the speed of 200 kilometers per hour, followed by Harbin-Dalian line, Beijing-Tianjin line, Jiaoji line, etc. And how to achieve high speed? Only the use of EMUs (not the traditional locomotive to pull the carriage), so that at least 50% of the carriage with power, this is the concept of EMU.

Therefore, whether it is the Guangzhou-Shenzhen Expressway 10 years ago, or the current CRH1 CRH2, CRH3 CRH5 trains are high-speed EMUs, which of course includes the CHR2 and CRH3 EMUs running on the Wuhan-Guangzhou line. Therefore, EMUs are for rolling stock running on railways.

The high-speed railway, that is, the high-speed railway, is for the railway line, the current high-speed bullet train has run in the ordinary passenger and freight lines, so the speed will not exceed 200 kilometers, there are running in the passenger dedicated line railway, the speed will not exceed 300 kilometers, and the Wuhan-Guangzhou line is in accordance with the international standard to establish a high-speed railway, the design speed is 350 kilometers per hour, in order to improve the popularity of China's high-speed railway, so it is called high-speed rail. In fact, those with a speed of more than 200 kilometers per hour should be regarded as high-speed rail.

In the language of the highway, the high-speed EMU is equivalent to your Mercedes-Benz car, your car can save roads, may not exceed 80 kilometers per hour, can take the national highway, may not exceed 110 kilometers per hour, may take high-speed kilometers, the speed may be 150 250 kilometers per hour. High-speed kilometers are "high-speed rail" for your car.

The difference between high-speed rail and bullet train is that the type of train is different, and the bullet train and high-speed rail refer to different types of railway lines, with the speed of the bullet train being 200 kilometers per hour and the high-speed rail being 300 kilometers per hour.

The rails of the bullet train and the high-speed rail are different, the high-speed rail line is laid by standard heavy rail, and the light rail, broad gauge, narrow gauge and maglev track are not within the scope of the high-speed rail line.

What is the difference between high-speed rail and bullet trains?

1. Speed difference.

High-speed EMU passenger train refers to the EMU train that runs on the passenger dedicated line at a speed of 250 km h and above, with a maximum speed of 250 km h to 300 km h, but the maximum speed of EMU train can reach 200 km h.

2. The running track is different.

While high-speed rail is high-performance and fast-moving, it can only run on newly built "high-speed rail", which is why we often call it high-speed rail. This is one of the reasons why many cities build high-speed train stations. Bullet trains can operate on previously built but modified regular railways, as well as on these newly built "high-speed railways".

3. The models are different.

There are two main types of automobiles, one is a single locomotive, which is only responsible for towing the vehicle and has no carrying function. The other is the power compartment, which not only has the towing capacity but also has the carrying function to transport passengers or goods on the car. The bullet train is a German train, while the high-speed train is a G-shaped train.

4. The performance is different.

High-speed rail has better performance and faster speeds. The bullet train can travel on two tracks.

5. The stops are different.

D-head trains mainly run on existing speed-up lines or intercity railways, while D-head trains run on high-speed rail trunk lines at a slower speed or make more stops than high-speed trains (G-head trains).

6. The system type is different.

High-speed rail refers to high-speed rail, which is the type of railway system described in terms of speed. A bullet train is a train that has power in its carriages. Except for the front carriages, each car can be electrified (pay attention to whether it is necessary).

However, these two terms have been redefined on domestic railways. In fact, the cars used on domestic high-speed railways are also cars, and it is a fact to call them cars.

The difference between high-speed rail and bullet trains: different names, different train times, different speeds, different rails, different driving requirements, different moving-tow ratios, etc.

1. The name is different: the full name of high-speed rail is high-speed EMU travel train, and the full name of EMU is EMU travel train.

2. The number of trains is different: the high-speed rail is a train number that starts with g, and g is the pinyin prefix with the high Chinese character. The bullet train is a train number that starts with d, and d is the pinyin prefix of the Chinese character.

3. The speed is not judged by Nian Suitong: the speed of the high-speed rail is more than 300 kilometers per hour, and the speed of the bullet train is more than 200 kilometers per hour.

4. Different rails: The rails used by high-speed rail are special rails, which is why they are called high-speed rails. The rails used by the bullet train can be either special rails for high-speed rail or ordinary rails that have been modified, with specific compatibility.

5. Different driving requirements: high-speed rail can be called a special line, so there are very few platforms set up on the whole line. There are more platforms set up on the whole line of the bullet train, and the main ones are intercity lines.

6. The dynamic towing ratio is different: high-speed rail belongs to a strong dynamic dispersion system, and the dynamic towing ratio (EMU trailer) is less than 1 to 1 and greater than 1 to 3. The EMU belongs to the weak power dispersion system, and the dynamic drag ratio is generally 1 to 5 and 1 to 6.
