China's high-speed railways are diverse in forms and rich in types. With multiple technologies with completely independent intellectual property rights, they have become China's new "diplomatic name card" and "image representative". China's high-speed rail, the "Chinese name card", continues to show its charm and bloom on the stage of the world's high-speed rail. With the advancement of the joint construction of the Belt and Road Initiative, more and more Chinese railways have taken root in Asia, Europe, Africa and other regions, which has promoted the interconnection between countries and brought more regions closer together.

Jakarta-Bandung high-speed rail-"our common pride"

Bandung is a tourist attraction in Indonesia. In summer, Jakartans who can't stand the heat flock to the refreshing and pleasant Bandung to escape the heat. There are long queues on the expressway, and it usually takes three to five hours to travel 150 kilometers.

On January 28, the landmark project of the Belt and Road Initiative between China and Indonesia, the turnout of Lanzeke Station of the Jakarta-Bandung High-speed Railway was inserted into the smooth construction. The track-laying base link line and Indonesia’s existing railway line successfully "hand in hand" for follow-up It is planned to create conditions for welding and laying of long rails of the Yawan high-speed railway.

The Jakarta-Bandung high-speed rail is the "first order" for China's high-speed rail system, all elements, and the entire industrial chain to go abroad. It is the first high-speed railway in Southeast Asia. It will not only greatly improve local traffic conditions, but also provide a lot of jobs for Indonesia.

Rama and Aji, who graduated from prestigious universities in Indonesia, chose to work on the Jakarta-Bandung high-speed rail project in order to "learn world-class construction technology". But the start was not smooth. "The process is more complicated, and the technology has never been touched." The two of them couldn't help but hesitate. The Chinese team's hard work and high degree of organization and discipline impressed them-"We believe that this project is different. Not only can we learn the most advanced technology, but we can also accumulate management experience."

After choosing to stay, Rama and Aji often consulted Chinese engineers. The Chinese teachers answered questions patiently and meticulously, and even opened a small Chinese class for them, focusing on learning engineering terminology. It didn't take long for the two to become technical backbones among local employees. Not only could they act as a "bridge" when communicating with the Chinese and Indonesian teams, they could also share their own work experience, share practical points of on-site operations, and impart skills to Indonesian employees who just entered the project.

In the eyes of Rama and Aji, the Jawan-Bandung High-speed Railway has placed people's good expectations for the future development of Indonesia: "The Jawan-Bandung High-speed Railway is not only a transportation line, but also provides us with new development space and lifestyle.

Rini Sumarno, Minister of State-owned Enterprises of Indonesia, praised that the Jakarta-Bandung High-speed Railway will facilitate people’s travel, promote the development of industries along the route, and have a positive impact on Indonesia’s economic and social development in a sustainable way. “The Jabban High-speed Railway is our common pride. ".

Mai Mai high-speed rail-"opened a new chapter in development"

Jeddah, the second largest city in Saudi Arabia, is located on the east bank of the Red Sea. It is home to Saudi Arabia’s largest port and King Abdulaziz International Airport. It is a must pass to Mecca and Medina.

Ahmed, a resident of Jeddah, and his ancestors have provided catering services for passing tourists, witnessing the development of transportation between the three cities. "In the beginning, it was horse riding or camel riding. The journey was difficult and took a long time. With the roads, millions of cars have become a unique scenery in Saudi Arabia, but the increasingly old infrastructure has become a new problem."

In 2018, the Mecca-Madina high-speed railway, which was constructed by Chinese companies, opened to traffic. This double-track electrified high-speed railway with the highest speed in the desert in the world has shortened the travel time between Mecca and Medina from the original 4 hours to two hours, and the annual passenger volume exceeded 15 million, which greatly eased The local traffic pressure has made the journey more comfortable.

As a local employee recruited by a Chinese company, Ahmed joined the construction of this high-speed railway. Recalling the construction process, he was full of admiration: the Mai-Mai high-speed rail line was mostly desert mountains, with complicated road conditions, hot weather, and temperatures as high as 55 degrees Celsius, making construction difficult; sandstorms that hit from time to time also caused wear and tear on electrical equipment and communication and signal facilities. And erosion, engineering technology faces huge challenges. There is no ready-made plan to learn from. Chinese engineers tried to find ways, found materials, and updated technology, and finally completed the project with quality and quantity.

In the past two years or so, the operation effect of the Mai-Mai high-speed rail has exceeded expectations. The train punctuality rate has exceeded 93%, the attendance rate has reached 82%, and the profitability has gradually increased. Ahmed said: "The opening of the Mai-Mai high-speed rail opened a new chapter in the development of Saudi transportation, and also injected vitality into regional development, making our lives better and better.

Hungary-Serbia Railway-"A gift for future generations"

"Woo-" In the loud whistle, the first train slowly entered Zemeng Station. In November 2020, the left line of the Serbia Zemun to Batajnika section of the Hungary-Serbia Railway was successfully transferred to traffic. The engineers from China waved on the platform, full of joy.

The Hungary-Serbia Railway connects Budapest, the capital of Hungary, with Belgrade, the capital of Serbia, with a total length of 350 kilometers. As a key project of the Belt and Road Initiative between China and Central and Eastern European countries, the Hungary-Serbia Railway is China's first high-speed rail entry into Europe and an important part of China's high-speed rail technology and equipment "going out".

In Belgrade, China Railway Communication and Signal Co., Ltd. built a train operation control system laboratory for the Hungary-Serbia Railway. This is China’s first overseas high-speed train control core technology laboratory. It can not only greatly reduce the workload of on-site testing and provide a solid guarantee for the project. In the future, it can also be used as a base for the operation and maintenance of the signal equipment of the Hungary-Serbia railway, serving the operation and maintenance technicians of the Serbian railway Provide training environment.

In the laboratory, Serbian engineer Urada is working with Chinese engineers to monitor the running status of trains in the currently open roads in Serbia.

"China's technology and solutions provide a complete set of signal equipment and engineering systems for the project to build a complete dispatch command and train operation control function. Relying on the command system, the central dispatcher can grasp the real-time status of all trains on the entire railway line and conduct dispatch and command. "Ulada pointed to the line operation diagram of the old Belgrade section of the Hungary-Serbia Railway on the big screen in the laboratory. "This system supports the entire production dispatch command of the Serbian Railway Department and guarantees the order of operation of the Hungary-Serbia Railway. As the project progresses In the future, all the operation plans of the Hungary-Serbia Railway can be dispatched and directed."

"At that time, factories and logistics centers will be built along the railway to boost Serbia's economic development. The Hungary-Serbia railway project is very important to Serbia and has far-reaching significance for future development. It is a gift to future generations."

When Serbian President Vucic visited the construction site, he expressed his gratitude to the construction team of China and Serbia. He said that the Hungary-Serbia Railway will greatly improve the living standards of the people and shorten the distance between Serbia and the hinterland of Europe. Editor/Sang Xiaomei
