Paoki-Chengtu Electric Railway Opens to Traffic

    CHINA'S first electric railway, the Paoki-Chengtu Railway, has been completed and the whole line was opened to traffic on July 1. It represents a milestone in the modernization of China's railway transport.
   Electrification of the 676-kilometre-long line is expected to double freight volume. This is equivalent to building a new railway, but at only one-tenth the cost. The use of electric locomotives speeds up the turn-round of waggons, cuts down the number of people required for inspecting and supplying water and coal, does away with dozens of steam locomotives and reduces the number of attendants on the trains. Electrification has also led to modernizing railway signalling and communications. After this transport artery linking southwest China with the country's railway network has been electrified, it makes still bigger contributions to the development of China's national economy.
   The Paoki-Chengtu Railway was built in the First Five-Year Plan (1953-57). It links Paoki in Shensi Province with Chengtu in Szechuan Province. For the most part the line traverses the rugged Chinling Range and the steep and hazardous Chienmen Mountains. For thousands of years before liberation, people found it extremely difficult to move about in this mountainous region so that they compared travelling in this section harder than climbing to the sky. Completion of this railway improved traffic in this region. But because of the long, steep grades and numerous tunnels and bends, the steam locomotives could only move slowly and their hauling capacity was limited.
   Electrifying this line started in 1958 on the northern section from Paoki, but it was curtailed later because of interference and sabotage by Liu Shao-chi's revisionist line. Work was resumed during the Great Proletarian Cultural Revolution which smashed the two bourgeois headquarters of Liu Shao-chi and Lin Piao.

In the course of construction, the Party organisation and revolutionary committee of the department for the electrification of this line led the workers and staff to repeatedly study Chairman Mao's directive "Be prepared against war, be prepared against natural disasters, and do everything for the people" and his teachings on maintaining independence and keeping the initiative in our own hands and relying on our own efforts. They also criticized the revisionist trash peddled by Liu Shao-chi and Lin Piao, such as servility to things foreign, the doctrine of trailing behind at a snail's pace and reliance on specialists to run factories. They were determined to do away with foreign stereotypes and to design and construct an electric railway with Chinese equipment and materials. With China's specific conditions in mind, workers, cadres and technicians formed many "three-in-one" groups to work out plans. Repeated experiments enabled them to use China-made aluminum-steel conductors instead of copper conductors which had been considered necessary for an electric railway. More than 400 technical innovations were adopted in the course of construction in the last few years so that the cost per hundred kilometres of electrified line later was less than half the cost at the initial stage.
   In line with Chairman Mao's teaching: "We must break away from convention and adopt as many advanced techniques as possible in order to build our country into a powerful modern socialist state in not too long a historical period," Chinese workers designed and made a number of new equipment and appliances and adopted advanced techniques. To reduce interference with nearby telecommunication, broadcasting and power transmission lines by the powerful current along the railway, for example, they designed and built after repeated experiments a booster transformer and return conductor with the help of departments concerned. Its use reduced the work of moving telecommunication lines, shortened construction time and cut building costs. This has provided valuable experience for building electric railway lines through large cities.
