Railway line heralds new trading dawn

Growth: Getting on the right track for economic expansion

Liu Baisheng, general director of the Kunming Railway Bureau, said locals would be the beneficiaries from this new railway.

Liu, who attended the National People's Congress session as a deputy in Beijing last week, told China Daily that the Yuxi-Mengzi railway starts from Yuxi, traversing Honghe Hani and Yi autonomous prefecture to cover an area of 48,200 square kilometers with a population of more than 6 million. The area is the major habitation of ethnic groups such as the Hani, Yi and Dai.

"With Kunming-Yuxi, Yuxi-Mengzi railway lines in operation, we have another option for transporting huge cargos long distances across Yunnan province. The new line will ensure faster speed and safer trips that sharply reduce the cost of transportation and increase profits," an entrepreneur in Honghe, who preferred to remain anonymous, said excitedly.

The tracks, mostly bridges and tunnels, were regarded as a soaring steel dragon by residents along the railway, who are optimistic about selling more local agricultural and sideline products and confident of developing the tourism industry.

The Yuxi-Mengzi Railway goes through the central Yunnan Plateau, with its mountains and canyons and some of the most intense areas of crustal tectonic movement. Started in September 2005, the new line took seven years to build, said Liu from the Kunming Railway Bureau "The same length of 141 km would only take two or three years in less rugged areas," he said.

Because of the special geographical conditions, Yuxi-Mengzi line builders were confronted with many challenges. More than half of the railway, 77 km, was built on bridges and tunnels. The Xiushan tunnel, 10,302 meters in length, is the longest railway tunnel in Yunnan province and runs through multiple faults and caves. It is famous for complex geological conditions and frequent changes in surrounding rock types.

The tunnel experienced at least 150,000 cubic meters of water leakage during construction every day. The volume increased to 230,000 cubic meters in the rainy season. "The tunnel builders had to endure suffocating humidity, hot days in summer and dust from the digging. Sometimes the collapse of sandstone and mudslides also threatened their lives," said Liu.

After seven years of hard work, they finally completed this Southern Yunnan "mountain road", marking an historic achievement.

Guo Huiming, head of the southern Yunnan railway construction project, was filled with emotion. "The completion of the railway was not easy," he remarked in a very understated fashion.

Guo said the engineering geology of the entire line was extremely complex, with many mountains and deep valleys. "We had poor construction conditions and the work was difficult. There were 173 intersections. The amount of stone ballast totaled 447,626 cubic meters. And there were the bridges and tunnels."

The Yuxi-Mengzi line, according to the former ministry of railways, was a high-risk project because it involved, among many geological challenges, karst high-pressure, water-rich complex geology, tectonic movements, rock-crushing, lots of groundwater in caves, flooding and sudden landslides.

The former ministry will be incorporated into the Ministry of Transport according to the just concluded session of the National People's Congress.

The former ministry and Yunnan provincial government attached great importance to the railway. "They came to the construction site several times to conduct research and to organize meetings to study and deploy technical solutions during construction," Guo said. "So we ultimately completed the Yuxi-Mengzi line thanks to their support."

Economic circles

On the map of Yunnan, the Yuxi-Mengzi Railway directly connects Honghe with Kunming, along with the existing Kunming-Yuxi Railway. Those areas are rich in mineral, biological, cultural and tourism resources. The most immediate effect of the railway's operation is to further enhance Kunming-Yuxi rail transport capabilities. "More importantly, it runs through several cities in central and southern Yunnan so economic factors can flow into each other more smoothly," said Duan Gang, president of the Yunnan Institute of Economic Research.

According to Liu from the Kunming Railway Bureau, Yunnan will become a big economic center, of which cores will be the central Yunnan Industrial District, the Kunming-Yuxi green industrial economy and Kunming-Yuxi leisure tourism economy. There will be two wings — the four cities of Kunming, Qujing, Yuxi and Chuxiong, with Kunming at the center.

The central Yunnan economic circle will be the economic, political, cultural and transportation center. The area will function as the core driving force to promote the integration of the province's economic resources and factors of production, Duan said.

Efforts have been made to promote the construction of central Yunnan Industrial District, focusing on high-end vehicle and equipment manufacturing, electronic information, biology, new materials, textile appliances and a modern services industry cluster area, according to the provincial government.

The Yuxi-Mengzi Railway and the Kunming-Bangkok Highway, along with the construction of the Pan-Asia Railway, will link the southern Yunnan economic circle with cities including Gejiu, Kaiyuan, Mengzi and Jianshui with Mohan and other important ports.

Rich natural and human resources in the area give it a huge advantage on top of the new communication links. The southern Yunnan economic circle is also part of the Kun-River Economic Corridor and there are also the central Yunnan economic connections to the Indian and Pacific Oceans east line and midline arteries.

Accelerating opening

The manufacturing capacity formed by the central Yunnan economic circle will steadily go to the southern Yunnan economic circle, targeted at the ASEAN market and other major importers around the world. The Yuxi-Mengzi Railway will also take on northward transport tasks from the southern Yunnan economic circle and also ASEAN regional resources in order to meet the central Yunnan economic circle requirement for industrial development.

Gejiu city contributes more than 90 percent of the country's output of refined tin. Xiaolongtan coal mine is Yunnan's largest open-cut brown coal mine, located in Kaiyuan.

In addition, the southern Yunnan region is also rich in iron, lead, gold and other mineral resources. These are indispensable for the development of the central Yunnan economic circle.

The Pan-Asia Railway will be the third Asia-Europe continental bridge linking China and ASEAN economies. As an important part of the east line of the Pan-Asia Railway, the Yuxi-Mengzi Railway will carry even more far-reaching significance.

In 2011, China's State Council announced its support to Yunnan province to accelerate the construction of an important frontier for Southwest China to open up, creating a historic opportunity for Yunnan. The Yuxi-Mengzi Railway will act as a highly significant link between China and Southeast Asian markets, further strengthening cooperation and exchanges between the countries, especially Vietnam, said Duan.

"For Yunnan, the railway has the positive significance of improving the province's railway network layout as well as the state of the railway business, promoting safe production and optimizing the railway industry structure. In the future, Yunnan will rely on the Pan-Asia Railway East Line to speed up the pace of opening-up and economic development and accelerate its integration into the global market," Liu Baisheng said.
