Recently, as the last long steel rail was pushed and put into place by the WZ-500 ballastless track laying machine on the 6th track of the Jakarta-Bandung High-speed Railway Halim Station, the track of the Jakarta-Bandung High-speed Railway was successfully laid from Dekarur to Halim, and the entire line was realized. The construction of the project has achieved major staged progress, laying the foundation for the smooth opening and operation of the entire line.

The track-laying main line of the Jakarta-Bandung high-speed railway has a total length of 142 kilometers and a maximum design speed of 350 kilometers per hour. There are 4 stations on the whole line: Halim Station, Karawang Station, Padalalang Station and Dekarur Station. The main line has 279.4 kilometers of track laying, including 112.8 kilometers of ballasted track and 166.6 kilometers of ballastless track. All of them adopt Chinese standard high-speed railway rails. The total amount of rails used is about 38,100 tons.

The Jakarta-Bandung high-speed railway project department overcame unfavorable conditions and construction difficulties such as high temperature rainfall, tight construction schedule, narrow space, cross operation, transportation and track laying on continuous 30‰ long slope sections, and strictly implemented the laying of ballasted track, ballastless track and ballastless turnout In the face of different construction environments, we insist on strengthening construction process management, refining operations, optimizing resource allocation, strengthening safety management, forming a track laying construction plan that is in line with the actual site, meeting the acceptance criteria for track laying accuracy, and ensuring The track is smooth, and the Jakarta-Bandung High-speed Railway has been successfully paved, laying a solid foundation for the opening of the Jakarta-Bandung High-speed Railway.

During the construction process, PowerChina facilitated the transfer of knowledge through the mode of passing on, helping, and leading, and taught Indonesian employees high-speed rail technology knowledge such as rail welding and track laying. Indonesian employees have accumulated a lot of high-speed rail construction experience in practice, which adds to their career More gold content has become a new force in project construction.

Jakarta, the capital of Indonesia, and Bandung, the fourth largest city, are connected by the Jakarta-Bandung high-speed railway. As a national strategic project of Indonesia, it is a landmark project of China-Indonesia practical cooperation and the joint construction of the Belt and Road Initiative. All elements and the whole industrial chain go abroad and go to the world. After the project is completed and opened to traffic, the travel time between Jakarta-Bandung Twin Cities will be shortened from the current more than 3 hours to 40 minutes, forming a fast passenger transport channel and realizing the interconnection of infrastructure in areas along the line, which will help Indonesia's economic and social development and deepen the economic and trade between China and Indonesia. Cooperation and people-to-people and cultural exchanges, and promoting the construction of the Belt and Road are of great significance.Editor/Ma Xue
