What are the high speed rail models in the world today and what are the characteristics of each?

The main technical and economic advantages of high-speed railway are as follows:

1. High running speed; Speed is the technical core of high-speed railway, the advantage distance of the car is less than 200km, the advantage distance of aviation is more than 1000km, and the advantage distance of the high-speed train is 180-1100km when the speed is 350kmh. However, in addition to time savings (advantageous distance), passengers should also consider factors such as fare, comfort, and safety.

2. Large transportation capacity;

3. Good safety performance and high comfort;

4. All-weather operation;

5. Low energy consumption;

6. Occupy the province of land;

The proportion of bridges in high-speed railways is large, and the bridges are mainly elevated, so it is the most economical to build high-speed railways in the case of low per capita arable land occupancy in China.

7. Low project investment;

Although the investment in high-speed railway projects is higher than that of ordinary railways, it is not higher than that of expressways.

8. Low environmental pollution;

The high-speed rail uses electric traction, which eliminates dust, soot and other exhaust pollution. The noise is 5-10db lower than on the highway. According to the cost of pollution control in China, if the high-speed railway is 1, the highway is the highway, and the aircraft is the same.

9. Good efficiency.

The economic and social benefits of high-speed rail are significant. The practice of France and Japan has proved that the return on direct investment is more than 12%, and the investment can be recovered within 10 years of operation. At the same time, the social cost of high-speed rail is also lower than that of highways and civil aviation.

According to research, the annual social cost savings of the Beijing-Shanghai high-speed railway can reach 22.3 billion yuan, and the total amount in 6-7 years is equivalent to the total investment. In addition, high-speed rail can also drive economic growth along the route and provide many employment opportunities.

Features of high-speed rail.

1.Since the high-speed railway is made of seamless steel rails, it is very smooth, which also makes the driving very safe and comfortable.

2. There are few curves in the high-speed railway, and the curve radius is large, and the turnouts are all movable high-speed turnouts.

3. The high-speed rail adopts a large number of viaducts and tunnels, which further ensures the smoothness of the high-speed rail and shortens the distance.

4. Compared with ordinary railways, the catenary of high-speed rail has better contact stability and durability.

5. The signal control system of high-speed railway is more advanced than that of ordinary railway.

What are the following characteristics of high-speed railway?

a.High passenger capacity.

b.There is less time for banquets.

c.Good security.

d.Comfortable and convenient.

e.Low energy consumption.

Correct answer: high passenger capacity, less time-consuming, good safety, comfort and convenience, low energy consumption, and dust.

China's railways are mainly high-speed railway scientific research and research, survey and design, construction, equipment manufacturing and operation management and other aspects of innovative theories, scientific and technological achievements and scientific and technological information, reflecting the latest developments of foreign high-speed railway science and technology, promoting scientific and technological exchanges and cooperation, improving the technical level of China's high-speed railway, and promoting the development of China's railway industry.

Advantages: 1. Less consumption and failure. The speed of high-speed rail is not less than 250 kilometers per hour, which shortens the time required for the journey.

2. Good security. The high-speed railway has a high level of safety due to its automatic operation in a fully enclosed environment and a series of perfect safety guarantee systems.

3. High punctuality rate. The high-speed railway is fully automated and can operate around the clock, unless force majeure is encountered.

4. Comfortable and convenient. The seats are spacious and comfortable, the walking performance is good, the operation is very stable, the shock absorption, sound insulation, the car is very quiet, and there is almost no inconvenience when traveling by high-speed train.

5. Low energy consumption. High-speed trains use electric traction and do not consume valuable liquid fuels such as petroleum, allowing for the use of various forms of energy.

Disadvantages: the cost and technical requirements of high-speed railway are high, the construction standards are strict and harsh, and the management and maintenance are complex and difficult, and the construction of high-speed rail is premised on rich passenger sources, strong economy, strong science and technology, suitable topography and advanced management.

Advantages of high-speed rail: copying.

1. The high-speed railway is very smooth to ensure the safety and comfort of driving, the high-speed railway is seamless rail, and the high-speed railway with a speed of more than 300 kilometers per hour adopts a ballastless track, that is, there is no stone in the integral track bed to ensure smoothness.

2. The high-speed railway has few curves, a large curve radius, and the turnouts are all movable high-speed turnouts.

3. A large number of viaducts and tunnels are used. to ensure smoothness and shorten distances.

4. The catenary of the high-speed railway, that is, the suspension of the wires on the top of the train, is also different from that of the ordinary railway, so as to ensure the contact stability and durability of the high-speed EMU.

5. The signal control system of high-speed railway is more advanced than that of ordinary railway, because of the high departure density, fast speed, and high safety.

Hello, the main technical and economic advantages of high-speed rail at present:

1) High passenger capacity.

2) Less time-consuming.

3) Strong conveying force.

4) Good security.

5) High punctuality rate.

6) Comfortable and convenient.

7) Low energy consumption.

A brief description of the development of the world's high-speed railways is to describe the progress of the world.

At present, the countries that run high-speed trains with a speed of more than 200 kilometers per hour are China, Japan, France, Germany, Italy, Spain, Belgium, the Netherlands, Sweden, the United Kingdom, the United States, Russia, and Switzerland, Austria, Denmark, Canada, Australia, South Korea, India and other countries that are actively building or planning to build.
