KAI Continues Ordering INKA Commuter Trains Despite Early Problems
Indonesia’s KAI is continuing to order commuter trains from domestic maker INKA despite problems with the trains already in service.
Seven INKA-built train sets operate on the Jakarta-area commuter network, run by KAI Commuter Indonesia.
Some of the seven sets had problems with doors and suspension, KAI chief Bobby Rasyidin said.
KAI and INKA say they have identified the causes and made fixes, including changes to suspension systems and door testing.
The eighth train set is in final testing, and KAI hopes to start operating it on December 1, 2026.
The ninth set has completed factory acceptance testing and is being brought to Jakarta for further tests, with service planned for early January.
KAI cancelled its plan to import used trains from Japan and has further INKA sets numbered 10 through 16 in its order plan.

What people are saying
We see that INKA’s TS-1 to TS-7 have indeed had many problems. But the most important thing is that INKA and we have managed to identify the problems and find solutions.
Now, the trend is that trainsets one to seven, God willing, no longer have suspension problems.
In TS-8 we are using the latest methodology to solve this door issue.
