The country of a thousand islands runs the Chinese high-speed train, and the Chinese high-speed rail once again amazes the world, and the golden business card is even more shining.

Adopt Chinese standard

With a clear whistle, a brand-new and beautiful comprehensive inspection vehicle turned on its headlights, slowly drove out of the Dekarur Station of the Jakarta-Bandung High-speed Railway and gradually accelerated... On November 16, local time in Indonesia, a high-speed The railway comprehensive inspection vehicle has conducted a comprehensive inspection of the line between Dekarur Station and No. 4 beam yard of the Jakarta-Bandung High-speed Railway, and the obtained indicators and parameters performed well.

The first test run of the Jakarta-Bandung high-speed railway was a complete success, which overjoyed the builders of the China-Indonesia railway. As a flagship project for the docking of China-Indonesia development strategies and the joint construction of the Belt and Road Initiative, the Jakarta-Bandung High-speed Railway is the first order for China's high-speed railway system, all elements, and the entire industry chain to go abroad.

How to understand the whole system, all elements, and the whole industry chain going abroad? According to the person in charge of the project, the whole system refers to the sub-systems of the Jakarta-Bandung High-speed Railway, such as the foundation, track, bridge, tunnel, catenary, communication signal, train control, EMU, and customer service, which all adopt Chinese standards; The whole process of high-speed railway construction and operation, such as survey and design, engineering construction, equipment manufacturing, operation management, and business development, fully adopts Chinese solutions; the whole industrial chain refers to the construction machinery, catenary, rails, EMUs, communication signals, Train control and other equipment are all manufactured by Chinese enterprises, covering the upper, middle and lower reaches of the high-speed railway industry chain.

In July 2022, the track laying of the Jakarta-Bandung high-speed railway began, and the CPG500 ballasted track-laying machine, which is well-known in China for high-speed rail track-laying, was unveiled in Indonesia. During construction, the ballasted track laying unit can directly lay 500-meter-long and 30-ton rails.

The high-speed EMUs of the Jakarta-Bandung high-speed rail, which has received much attention, also come from CRRC, and are designed and manufactured by CRRC Sifang Co., Ltd., a subsidiary of CRRC. The train adopts Chinese standards, relying on the world's fastest commercial operation speed of 350 kilometers per hour Fuxing Chinese standard EMU technology platform, adapting to the local operating environment and line conditions in Indonesia, and tailor-made for the Jakarta-Bandung high-speed railway. As my country's first high-speed EMU exported abroad, the Yawan high-speed EMU is another masterpiece of China's high-end equipment going global.

As Xin Xuezhong, commander of the Jakarta-Bandung high-speed rail contractor consortium, said: "All the Jakarta-Bandung high-speed rail uses the most advanced and mature technology in China." At present, 93% of the civil engineering of the Jakarta-Bandung high-speed rail project has been completed.

Highlight Indonesian elements

In Dekarur Town, Bandung City, West Java, Indonesia, a brand-new station surrounded by mountains has become a popular check-in point. It is the Dekarur Station of the Jakarta-Bandung High Speed Rail.

Following the design concept of blending mountains and rivers and the beauty of nature, Dekarul Station adopts high and low curve design on the facade of the building, which looks like mountains and emerald green, echoing the surrounding mountains; the facade materials adopt large-area glass curtain wall and aluminum panel curtain wall, Like the sparkling water, it echoes with the surrounding villages and streams, highlighting the beauty of nature and agility.

According to reports, the Jakarta-Bandung high-speed rail line has a total of 4 stations, namely Halim Station, Karawang Station, Padaralang Station and Dekarur Station. The architectural design intentions of the four stations are drawn from the natural mountains and rivers of West Java, the beautiful arcs of the waterfront coast and Indonesian weaving culture. The use of modern design techniques shows the sense of speed, technology and future of high-speed rail.

The unique design can be seen everywhere in the Jakarta-Bandung high-speed rail project, and has been loved and welcomed by the Indonesian people. For example, the Jakarta-Bandung high-speed train body is painted in silver and red, and the red color comes from the red and white national flag of Indonesia. At the connection between the front face of the car and the carriage, the red polygonal patterns in different shades complement each other, imitating the texture of the Indonesian national treasure animal lizard Komodo dragon. In the compartment, the gray color of the VIP seats is taken from the world-famous Borobudur Tower in Indonesia. The crimson red of the first-class seats echoes the red of the Indonesian national flag on the body, and the gray-blue design of the second-class seats makes people feel like they are in Thousand Islands The boundless beach of the country. The Indonesian intangible cultural heritage "Badik" style auspicious cloud pattern inlaid on each seat is full of Indonesian local flavor.

The high-speed EMUs of the Jakarta-Bandung high-speed railway were officially delivered

"Respect for Indonesian culture is a key design concept of the Jakarta-Bandung high-speed rail EMU." Zhang Fangtao, designer of CRRC Sifang Co., Ltd., said that Indonesian local cultural elements were incorporated into the design of the EMU, and the appearance of the vehicle and the interior interior of the train were targeted. It is a major focus of the design team to improve and optimize the configuration of passenger facilities.

In addition to incorporating Indonesian local elements, the Jakarta-Bandung high-speed rail design and construction team also fully considered the complex natural environment along the high-speed rail. The Java Island area where the Jakarta-Bandung High-speed Railway is located is prone to earthquakes and volcanoes, while Bandung is located in the regional subsidence section. The rainfall along the line is extremely abundant, the climate is complex and changeable, the mountains and rivers are criss-cross, and the geology of the rock formations is complex. The construction is quite difficult.

Looking back on the first time he led a team to work in Indonesia in 2015, Xia Jian, the overall design director of the Jakarta-Bandung high-speed rail project, was very moved. In order to avoid major unfavorable geology such as volcanoes, active faults, and landslides, the Chinese technical team collected large-scale regional geological maps and satellite image data to mark volcanoes, fault zones, landslides, etc. Major unfavorable geology, and carry out detailed on-site geological survey and mapping, and analyze the causes and changes of unfavorable geological conditions such as regional subsidence. Braving the sweltering heat and humidity, Xia Jian and his team traveled almost every corner of the expected railway line.

After the start of construction, especially during tunnel construction, the design team is always on site. "Every 5 meters or 10 meters in the underground engineering, the strata will change. At this time, my designer and I need to dynamically adjust the protective measures according to the actual excavation situation." Xia Jian introduced, the earthquake resistance of the Yawan high-speed railway tunnel The fortification intensity is very high, all in the range of 8 to 9 degrees.

In order to solve the problem of climate adaptability, the CRRC Sifang design team built an environmental testing platform in Indonesia that is equivalent to that in China. Through in-depth research on the local climate and environment, combined with domestic advanced and mature technical experience, it has gradually clarified the impact of the local climate and environment on EMUs. Influencing factors of group operation.

The salt spray content in the air in coastal areas is high, and the ultraviolet radiation intensity in low latitude areas is very high. The design team adopted a high-standard corrosion-resistant design and applied advanced new coating technology and protection technology to make the EMU resistant to salt spray, UV aging resistance increased by 50%. Considering the characteristics of high temperature and high air humidity along the Jakarta-Bandung High-speed Railway, the design team optimized the air-conditioning system of the EMU and developed a humidity control function, which can control the temperature of the carriage below 26°C and the humidity below 60%, making the body feel comfortable. It is more comfortable and improves the travel comfort of passengers. In order to adapt to the multi-slope line conditions of the Jakarta-Bandung High-speed Railway, the design team also set a high acceleration mode for the EMU to achieve the goal of quickly improving the traction performance on the slope.

"The local environment has brought great challenges and pressure to the team. The setting of anti-corrosion level, temperature and humidity, and the innovation of traction mode all require the comparison of design parameters and repeated simulation calculations to verify the feasibility." Zhang Fangtao said, "When After the problem was finally solved, the excitement in everyone's hearts is beyond words."

Yogi, a native of Bandung, Indonesia, is looking forward to the opening of the Jakarta-Bandung high-speed railway. In his impression, in the 1990s, it took a day to travel from Bandung to Jakarta, starting in the morning, and it was getting dark; around 2000, the expressway was opened, and theoretically it took more than three hours to get there. But in fact it is difficult to achieve, because there are always traffic jams; until the opening of the railway between Jakarta and Bandung, it is guaranteed to arrive in about 3 hours. The new Jakarta-Bandung high-speed rail has shortened the travel time between the two places from 3 hours to 40 minutes, which is almost unimaginable for Yogi. He plans that in the future, if he gets on the bus in Bandung at 8:00 am, he can catch up with the meeting in Jakarta at 9:30 am; and when he returns by car after get off work, he can still rush back to Bandung for dinner.

"I used to see China's high-speed rail on TV, but this is the first time I have seen it with my own eyes." Putra, a ladder truck driver on the Jakarta-Bandung high-speed rail project, is also very much looking forward to the completion and operation of the Jakarta-Bandung high-speed rail. He lives in Jakarta and usually only goes home once a month. "It will be convenient for me to go home when the Jakarta-Bandung high-speed rail opens to traffic."

Java Island, where the Jakarta-Bandung High-speed Railway is located, is the fifth largest island in Indonesia, and also the island with the largest population and highest population density in Indonesia. Jakarta, Surabaya, Bandung, Semarang, Yogyakarta, Bogor and other major industrial, commercial and tourist cities are concentrated here. The resident population is about 145 million, accounting for about half of the Indonesian population. It is the most economically and culturally developed region in Indonesia. According to reports, after the completion and operation of the Jakarta-Bandung high-speed railway, passenger transport services, equipment maintenance and related supporting industry extension services will create 30,000 jobs every year.

The Jakarta-Bandung High-Speed Railway is a popular project jointly created by the people of the two countries. In fact, during the construction period, the Chinese side allocated workers according to the 1:4 ratio of Chinese and Indonesian workers, and the highest reached about 1:7, bringing a total of 51,000 local jobs to Indonesia. China has also continued to increase the training of Indonesian employees. Through the establishment of training institutions, "masters leading apprentices" for Chinese employees, and on-site training, etc., China has supported Indonesia to build its own high-speed rail technical force and workforce, and has trained 4.5 Indonesian employees. million people. Han Gaolu, the first chairman of Indonesia China High Speed Railway Co., Ltd., said that during the construction of the Jakarta-Bandung high-speed railway, the sense of trust between the two sides has been continuously enhanced.
