The joint commissioning and testing of the Jakarta-Bandung High-Speed Railway started on Monday, marking a milestone in the construction of the railway project.

The exercise is conducted before the opening of a high-speed railway to ensure the safe and smooth operation of the trainsets.

By conducting dynamic testing using a comprehensive inspection train on the newly constructed high-speed railway, the performance of various systems, such as the tracks, power supply, overhead catenary system, communication, signaling and early warning monitoring, is tested and verified.

All civil engineering work, such as roadbeds, bridges, culverts and tunnels, has been completed. Preparations for operation are being carried out in an orderly manner.

After the completion of the joint commissioning and testing, further running trials and safety assessments will be conducted before the official commencement of operation.

The high-speed line, a landmark project under the China-proposed Belt and Road Initiative, connects Indonesia's capital Jakarta and another major city Bandung.

With a design speed of 350 kilometers per hour, the railway spanning 142.3 kilometers will cut the journey between Jakarta and Bandung from over three hours to around 40 minutes.
