No matter what is done overnight, it is all gradual and gradual, and qualitative change is caused by quantitative change, which is the law of the development of all things, and it is also an objective fact.
Many of our friends may seem to China that China's high-speed rail suddenly took off after 2008 on the surface, but this is not the case, and it also abides by the objective law of the development of things.
Before 2008, China was vigorously developing high-speed rail technology and putting it into practice, thus laying a lot of technical foundations, thereby helping China's high-speed rail take-off, the typical representative of which is the technological transformation of Guangzhou-Shenzhen railway.
Since the 90s of the 20th century, the concept of time has gradually changed in China's coastal areas, especially in the economically developed areas of Guangzhou and Shenzhen.
At that time, the railways in these two places faced fierce competition with highways and air transport, and were at a competitive disadvantage for a long time due to the speed of trains and the quality of passenger services.
In order to reverse the passive situation of railway transportation and attract a large number of passengers, the speed of train operation has become an obstacle in front of the railway authorities.
As the saying goes, if you are not afraid that you can't solve the problem, you are afraid that you won't be able to find the problem.
After the railway authorities discovered the problem, although they could not immediately increase the speed of trains, they have studied the matter as a special project.
After full research, the railway authorities proposed and implemented the Guangzhou-Shenzhen Railway Technical Transformation Project in 1991.
This process is not smooth sailing, during which many technical problems and construction problems once became an insurmountable peak for the railway authorities, but the railway people who bravely climbed the peak were not deterred by the difficulties, but became more and more courageous, and continued to learn and study related technical problems.
Until 1994, after nearly 4 years, the technical transformation of the Guangzhou-Shenzhen Railway was finally completed.
Through technological transformation, the Guangzhou-Shenzhen Railway, as a double-track electrified railway with passenger and freight co-line, has achieved a design speed of 160 200 kilometers per hour for passenger cars.
The Guangzhou-Shenzhen Railway, which has completed the technical transformation, has continuously improved its supporting facilities and equipment, and introduced X2000 tilting trains from Sweden.
As a result, the actual running speed of the Guangzhou-Shenzhen Railway passenger train once exceeded 200 kilometers.
As a result, the competitiveness of the Guangzhou-Shenzhen Railway has skyrocketed, and the return of passengers has been substantial, which has also made the railway authorities taste the sweetness of the development of high-speed railways and strengthened the direction of developing high-speed railways.
At the same time, a large amount of basic data and technical strength have been accumulated through the technical transformation of the Guangzhou-Shenzhen railway, especially the technical capabilities in railway design, construction and construction have been greatly improved, laying a technical foundation for the take-off of China's high-speed railway.
