On June 22, 2023, the comprehensive testing of the joint debugging and testing of the Yawan high-speed railway showed that the train had reached a speed of 350 kilometers per hour for the first time, marking that the Yawan high-speed railway had reached the design speed standard and achieved the phased task goal of the joint debugging and testing.

Since the joint commissioning and test of Ya'an Wanzhou High speed Railway officially began on May 22, 2023, China Railway International Corporation led China Railway Beijing Group Co., Ltd. and China Academy of Railway Sciences to jointly carry out the step by step speed increase test, comprehensively detect the speed level of the train at 180 km/h, step by step increase to the design speed of 350 km/h, fully verify the functions of Ya'an Wanzhou High speed Railway track, power supply, catenary, communication, signal, early warning monitoring and other systems The performance and various system indicators have met the design requirements, providing strong support for subsequent operational testing and operation.

The stepwise speed increase test of high-speed rail refers to the operation of comprehensive testing trains on newly built high-speed railways according to the requirements of the joint debugging and testing outline, and gradually increasing the speed until it reaches 110% of the designed speed of the line. Therefore, according to the design standard of the Yawan high-speed railway with a maximum operating speed of 350 kilometers per hour, the maximum detection speed of the comprehensive inspection train will reach 385 kilometers per hour.

In order to make preparations for the opening and operation of Ya'an Wanzhou High speed Railway, from the end of February 2023, China and Indonesia will work closely together. The Chinese side has conducted professional training for Indonesian students in high-speed railway operation positions such as Multiple unit drivers, Multiple unit mechanics, and operation control center dispatchers, providing talent and technical support for the high-quality opening of Ya'an Wanzhou High speed Railway.

With a total length of 142.3 kilometers and a maximum operating speed of 350 kilometers per hour, the Jakarta Wanzhou high-speed railway connects Jakarta, the capital of Indonesia, and Bandung, the famous tourist city. It is a landmark project of the the Belt and Road Initiative and practical cooperation between China and Indonesia, and also the first overseas construction project of China's high-speed railway with a full system, all elements, and all industrial chains. The whole line adopts Chinese technology and Chinese standards.

After the completion of the project, the travel time from Jakarta to Bandung will be shortened from more than 3 hours to 40 minutes, which will greatly improve the local traffic conditions and drive the economic and social development along the line. It is of great significance to deepen the practical cooperation between China and Indonesia, promote the high-quality development of the the Belt and Road and the implementation of Indonesia's concept of global maritime fulcrum.
