The Yawan High-speed Railway (the full name is Jakarta Bandung High-speed Railway) is a flagship project jointly built by China and Indonesia. It starts from the capital Jakarta in the north and connects with the famous tourist city Bandung in the south. The total length is 142 kilometers, and the designed operating speed is 350 kilometers per hour. It is the first high-speed railway in Indonesia and even the whole Southeast Asia. The project was fully started in June 2018 and the first test operation was completed on November 16, 2022. After opening to traffic, the travel time between Jakarta and Bandung will be shortened from more than 3 hours to 40 minutes.
