What is the average speed of an EMU and what is the speed of the EMU?

The main operating speed is 160 km - 250 km.

The body of this train mainly uses the Harmony EMU (except for the CRH380 series models and this series of models, which serve as ordinary EMU trains.

trains) and Fuxing EMUs.

Except for the CR400 series models and this series of models, which are used to run ordinary EMU trains), the main operating speed is 160 kilometers per hour and 200 to 250 kilometers per hour.

The total range of trains is D1-D9998, of which D1-D3998 is the cross-railway bureau.

Trains, D4001-D9998 are the trains under the management of each railway bureau. The standard pronunciation of the railway system is "bullet train * times", and the general public is accustomed to pronouncing it as "d* times".

Ordinary EMU trains are new trains added from the sixth major speed increase of China Railway on April 18, 2007, and are the first to be on the Beijing-Shanghai Railway.

Upward line. Subsequently, it was in Beijing-Harbin, Beijing-Guangzhou, Longhai, Shanghai-Kunming (Zhejiang-Jiangxi section), and Jiaoji line.

and so on, and the implementation of the speed of the existing trunk line to 200 kilometers to run such trains.

The speed of the bullet train on the existing line was 200 kilometers per hour in the early days, and it was adjusted to 160 kilometers on August 16, 2011. After the new passenger dedicated line is put into operation, most EMU trains no longer operate on the existing line in order to reduce the pressure on freight transportation.

Merit. 1. Strong acceleration ability.

In China, compared with traditional trains, EMUs have more outstanding advantages in terms of traction.

Larger. 2. The marshalling comes with its own operating power.

Under normal circumstances, in the designed use environment, there are EMUs in the EMU marshalling to provide power to ensure the operation mode of its design, without the need to use other vehicles such as locomotives and rail cars as power**.

3. Easy reversing.

In the traditional train in China, the reversing step in operation is "entering the station and stopping - removing the front locomotive - re-attaching the locomotive at the end of the train - leaving again". The EMU, as long as it is still in the normal state of group operation, the two ends of the train must be operated by the driver's cab, each driver's cab can control the power and braking equipment on the whole train, and the driver only needs to go to the driver's cab at the other end of the train when changing directions.

The speed of the bullet train is generally 200 kilometers per hour. High-speed rail is a little faster, and the speed of high-speed rail is generally at least 250 kilometers per hour. Velocity is an expression of velocity that refers to the total distance traveled by an object in 1 hour, and the unit of speed is kilometers (kilometers).

Speed is commonly used in transportation, but it is not the standard unit of speed in the International System of Units.

EMU introduction

The full name of EMU is power vehicle, which refers to the vehicle equipped with power unit in the rail transit system, including locomotive and power carriage. The motor car is equipped with driving wheels, and the corresponding undriven vehicle is a trailer. For a train to run properly on the tracks, it must have a bullet train that provides enough traction for the entire train, but without trailers that are not powered.

EMUs are railway vehicles equipped with wheel-driven machinery and equipment, not EMUs. There are not only bullet trains in high-speed trains, but also bullet trains in all types of trains, including normal speed EMUs, ordinary speed trains, subway trains, light rail trains, monorail trains, and maglev trains.

The bullet train has provided great convenience to people's lives and brought a convenient and comfortable life experience to human beings. Tiannan Haibei is no longer far away, the wonderful world is in front of you, ordinary people's travel plans suddenly increased, and the bullet train can become the first choice for travel.

On the line that only runs the mobile train, the maximum speed of the bullet train is 200 220 kilometers per hour, while on the line of high-speed rail and bullet trains, the speed of the mobile potato dispatch car should be maintained at more than 250 kilometers per hour. <

On the line, which is only moving, the maximum speed of the bullet train is 200 220 km/h; On the line of mixed high-speed rail and bullet trains, the speed of the bullet train should be maintained at 250 kilometers per hour (if this is slow, it will affect the operation of the high-speed rail), the speed of high-speed rail is between 290 and 310 kilometers per hour, Shanghai-Nanjing and Wuhan-Guangzhou are 300 and below, and Beijing-Shanghai is 310 and below. On the same high-speed railway, the high-speed rail is about 50 kilometers per mega-kiloei-hour faster than the bullet train. If you take into account the extreme values (which are not on the same high-speed rail at this time), it is about 100 km/h.

We need to calculate the speed of the motor car and the car first, and then calculate the speed of the motor car, and then calculate the speed of the motor car is several times the speed of the car.

The speed of the car is known to be 60 km/h.

The speed of the EMU is known to be 250 km/h.

According to how many times the speed of the EMU is the speed of the car = the speed of the EMU The speed of the car, it can be calculated how many times the speed of the EMU is the speed of the car:

So, the speed of a bullet train is twice that of a car.

The speed of the motor car and the car is different, and it needs to be judged according to different situations. Generally speaking, bullet trains travel much faster on high-speed rail than cars, because high-speed railways are designed and built specifically to improve the speed of trains, the efficiency of transportation, and the safety performance. Whoa.

Taking China's high-speed bullet train as an example, its maximum speed can reach 350 kilometers per hour, while the speed of most ordinary passenger cars cannot exceed 120 kilometers per hour. Therefore, if the speed of the two is compared, then the speed of a high-speed bullet train may be more than two to three times faster than that of a car fingerlift.

Of course, this is just a simple speculation. The specific speed difference also takes into account a variety of factors, such as road conditions, vehicle type, distance traveled, and so on.

The approximate range of the speed of the bullet train is 200 350 kilometers per hour, so it can be concluded that the bullet train can travel per hour. In addition, because of the different types of EMUs, their ** is also different, such as the Harmony CRH2B is 100 million yuan, CRH2A is about 90 million, CRH3C is about 200 million, etc., so the average cost of an ordinary EMU 8 cars must be 100 million yuan.

However, in the case of high-speed rail EMUs, taking the Fuxing as an example, a Fuxing ** train will probably cost about 100 million yuan, and the unit price of the alpine EMU is slightly higher than that of ordinary EMUs. In addition, the cost of Harmony CRH380B is the most expensive, about 100 million, and CRH380A is about 300 million.

Speed of other trains:

1. The speed of high-speed rail is generally at least 250 kilometers per hour.

2. The speed of the bullet train is generally about 200 kilometers per hour, and the express passenger train: the bottom of the car with a speed of 140-160 kilometers per hour is used, and the line with a speed of 140 kilometers per hour and above is used.

3. Fast passenger trains: use the bottom of the car with a speed of more than 120 kilometers per hour and stop at larger stations.

4. Ordinary passenger trains: including ordinary passenger express trains and ordinary passenger slow trains, using the bottom of the car with a speed of 100-120 kilometers per hour, and the stops are according to the needs of passenger flow. The stops of the ordinary passenger slow train are not subject to the distance between the stations.
