INFRASTRUCTURE testing and commissioning commenced on the Jakarta - Bandung high-speed line in Indonesia on May 22.

According to China Railway International, which is leading the joint commissioning and testing programme, work will ensure safe and stable operation of the high-speed train fleet on the new 142.3km line as well as the performance of track, power supply, catenary, signalling and communication systems, as well as monitoring systems.

China Railway International is working with China Railway Beijing Bureau Group, the China Academy of Railway Sciences as well as local Indonesian companies on the testing and commissioning work.

Tracklaying was completed in March after construction commenced on June 9 2018. The Indonesian government said in November 2022 that it hoped to open the line in June 2023.

The line will be operated using a fleet of 12 350km/h eight-car Yawan high-speed trains supplied by CRRC Qingdao, which will offer a journey time of 40 minutes between the two cities, down from around 3h 40min at present.

Construction of the project was conducted by PT Kereta Cepat Indonesia-China (KCIC), which is a consortium of state-owned Indonesian companies (60%) and China Railway Engineering and other Chinese companies (40%). The line has entirely adopted Chinese railway equipment, the first time China has exported all of the technology for an international high-speed project.

The project has ultimately come in nearly $US 2bn over the initial budget $US 6.07bn due to technical issues and the unstable nature of civil works.
