On March 2, 1969, an armed conflict broke out between the Chinese and Soviet armies on Zhenbao Island on the border between China and the Soviet Union in Heilongjiang, and the relationship between the two countries fell to a freezing point. The rapid changes in the international situation have once again made the construction of the third line urgent.
Premier Zhou Enlai of the State Council, on behalf of the State Council and the Central Military Commission of the Communist Party of China, issued an order to the Southwest Railway Command to postpone the opening of the Chengdu-Kunming Railway for two years and must be opened to traffic on July 1, 1970.
The construction work of the Chengdu-Kunming Railway has been fully rolled out again. Out of the importance of this railway, Chairman Mao deliberately found the newly appointed Southwest Third Line Peng Dehuai, deputy commander-in-chief of railway construction, talked. He said: "If the railway is not repaired well, I can't sleep well! If there is no money for the project, I will take out my wages and contributions, and the Chengdu-Kunming Railway must be opened up. "With the care and support of the central leadership, the construction of the Chengdu-Kunming Railway has once again set off a climax.
At that time, Wu Baosheng, political officer of the 48th regiment of the 10th Division of the Railway Corps, recalled that after the Chengdu-Kunming Railway was rolled out again, everyone repaired Lu’s enthusiasm is unabated. Everyone keeps on spinning, and they often work for 48 hours without leaving work.
Li Yonghua, a soldier of the 1st Division, 1st Regiment, 1st Railway Soldier, said that at that time, the soldiers wrote diaries and wrote the fifteenth day on the date. On the sixteenth of the week, he will only start writing on Monday if he takes a half-day holiday and washes his clothes.
But soon the project encountered It’s difficult. Take the section from Yangjiuhe Station to Heijing Town Station, the straight line distance between the two points on the map is only 20 kilometers, but the altitude difference between the two places is as much as 364 meters. If it’s bad, the train simply can’t climb, even if it is towed by a more powerful two-machine.
In order to solve the problem of train crossing the mountain, experts have designed a plan for the exhibition line. Take a bicycle for example. , If we ride a bike uphill, we can go straight up without going up the S-shaped route. This section of the S-shaped route will be longer than the straight-line distance, and this stretched route is called the exhibition line.
According to the specific topography between Yangjiu River and Heijing Town, the expert team designed three major exhibition lines, Liudu River, Bagler and Farah, and the train traversed 42 kilometers in the valley.
Crossing the river 21 times, which is equivalent to doubling the distance before finally climbing on the southern Yunnan Plateau. This is why the well-known "Eight Monsters of Yunnan" will say "The train is not as fast as the car, and the car does not go. It’s the reason for it.
In addition to these three lines, there are five other lines like this on the Cheng-Kun Line and its branch lines. They are called Cheng-Kun Line’s Eight exhibition lines.
In the construction of the Chengdu-Kunming Railway, experts have created and promoted more than 50 new technologies, created and innovated more than 760 pieces of major equipment, and accumulated rich experience for China’s railway construction.
July 1, 1970, Cheng-Kun Railway It was successfully completed and opened to traffic. The first row of floats full of representatives of workers, peasants and soldiers drove from Chengdu to Kunming, and the first row of floats from Kunming went north to Chengdu.
Chengkun RailwayThe building has truly changed the living environment and way of ethnic minority compatriots. Take Ganluo, located in Liangshan Yi Autonomous Prefecture. The former Ganluo Mountains were surrounded by thorns, and only a rugged path connected to the outside world.
After the Chengdu-Kunming Railway was opened to traffic, the wide asphalt road passed through the city. The newly built buildings lined both sides of the road. Groups of Yi girls in bright pleated skirts are inThe store goes in and out. Coaches full of passengers drove from the county seat to all directions.
After the Chengdu-Kunming Railway was opened to traffic, the huge treasure hidden in the mountains was gradually transported to various parts of the country to support the economy Someone once commented on the construction of the Chengdu-Kunming Railway: The construction of the Chengdu-Kunming Railway and the Panzhihua Iron and Steel Plant has affected and changed the fate of at least 20 million people in the southwest region, and made strides forward in the desolate area of the southwest.50 years!
There is no flashy rhetoric, but the great value of the Chengdu-Kunming Railway and its An important position in the economic construction of Southwest China. And this is what the decision makers and builders of the Chengdu-Kunming Railway were most looking forward to seeing. Half a century later, the Chengdu-Kunming Railway is still the main artery of economic construction, and it continues to influence generations of Chinese people in the southwest of the motherland.
