trains. As the main force of land transportation, railway occupies a monopoly position for more
than one century. But since twentieth Century, with the rapid development of vehicle, aviation and pipeline transportation(管道运输), railways are constantly being impacted by new transport tools, so it is urgent to develop high-speed railways.

Neither building new lines nor reconstructing old lines. largely depends on the use of tilting car bodies consisting of vehicles, and the mixture of passenger trains and freight trains.
Faster than other ground transportation
Although air transit moves at higher speeds than high-speed rail, total time to destination can be increased by check-in, baggage handling, security, and boarding, which may also increase cost to air travel, so HSR is best suited for journeys of 1 to 4 hours (about 150– 900 km), for which the train can beat air and car trip time.

Japan, Germany and France are developing Magnetically Levitated Train( 磁悬浮列车) to make the car float up to a certain height on the track, and then use the linear motor(直线电动机) as a driving force to propel the train forward. The speed of the test has reached 517 kilometers.

Faster than other ground transportation
The top speed of the high-speed train can reach 350km/h, but the car only 120km/h,so this is a great saving of time.From the following picture, we can see that it takes only five hours if you take a high speed rail from Beijing to Shanghai, but the ordinary train takes nearly 20 hours.

GERMAN(ICE):
Following the French TGV, in 1991 Germany was the second country in Europe to inaugurate a high-speed rail service, with the launch of the ICE on the new HannoverWürzburg high-speed railway, operating at a top speed of 280 km/h .
More transport capacity and less cost
In China,the passenger capacity of the high speed rail can reach hundreds of millions of times, while the passenger volume of the aircraft is only a few million times.As we all known , China has the largest population, and most of us will choose trains as the main way of transportation, therefore this requires that our HSR must have a large capacity.
DEVELOPMENT
At present, the high speed railways built by European countries are basically independent of each other. but the further development trend of high speed railway is networking. In the future, it will be developed into a high-speed railway network connecting both domestic and international, and will be connected with the existing railway lines.

Definitions
High-speed rail is a type of rail transport that operates significantly faster than traditional rail traffic, using an integrated system (集成系统) of specialized rolling stock and dedicated tracks. While there is no single standard that applies worldwide, new lines in excess of 250 kilometres per hour and existing lines in excess of 200 kilometres per hour are widely considered to be high-speed, with some extending the definition to include lower speeds in areas for which these speeds still represent significant improvements.
