World high-speed railway development.

I. overview of world high-speed railway development.

(1) the rise of high-speed railways.

In 1964, Japan's Shinkansen opened a new era of world railway development.

In 1981, the French high-speed railway, the high-speed railway on a new stage of development, and promote the development of a European high-speed rail, Italy, Germany, Spain and other countries successively into the construction of high speed railway line.

(2) China high-speed railway.

In 2008, the Chinese mainland owned the first high-speed railway, the beijing-tianjin inter-city railway, with a speed of 350 kilometers per hour.

In 2009, China had the world's longest high-speed railway with the longest running speed and the highest operating speed.

(3) France high-speed railway.

France has long been the world leader in developing high-speed trains, setting a world record of 515.3 kilometers per hour in 1990.

On April 3, 2007, a TGV test was carried out on the newly completed east rail line of Paris - Strasbourg, with trains running at 574.8 kilometers per hour.

High-speed railway is the pride of the French technology renowned in the world, but in the economy is in the back of national heavy burden, the French high-speed railway is only 1282 kilometers, the French plan in the first ten years of the 21st century, southeast of the line extend to marseille, even built to the south of Italy and Spain in Europe line and Paris to Strasbourg eastern Europe line in Germany.

High-speed rail is a classic French legend-technical success is inextricably linked to financial disaster.

Characteristics of high-speed railway in France:

The emu adopts the power centralized mode and the articulated carriage.

The multi-current power supply and simple chain suspension catenary can use the 1500V 3000V dc power supply of the general line, and can also use the high-speed line 25KV ac power supply.

TVM train control system which meets the ETCS standard.

Focus on the security and reliability of the system.

High standard, high quality line.

(4) Japan high-speed railway.

In the face of fierce competition in developed countries such as France and Germany, Japan has said that the 21st century is the era of Shinkansen.

Japan will make Shinkansen's increased from the current 2000 km to 2000 km, then the country will be formed to Tokyo in Japan as the center of the National Day traffic circle (i.e., the same day arrived in Tokyo any outside big cities).

Characteristics of high-speed railway in Japan:

There is an increasing proportion of bridge and tunneling in the line.

Establish the test section and solve the key technology through experimental research.

The high-speed train USES the dynamic dispersive type, continuously reduces the axle weight, improves the train performance comprehensively.

The train has a high density of operation, a large number of passengers and a large number of passengers.

Safety performance, no passenger fatality.

Increase service facilities, improve service quality and facilitate passenger transfer.

Germany's high-speed rail technology reserves are no less than France's. In 1988, they were able to speed up the speed of the driving test at 400 kilometers per hour, reaching 406.9 kilometers.

But Germany's practical high-speed railways didn't start building until the early 1990s.

At present, there are about 2620 kilometers of high speed transport corridors.
