A 2,772km Kalimantan railway is on the table, with China again in the frame

Indonesia wants to lay rail across Kalimantan, and the shape of the plan is already large. Writing for the Lowy Institute's Interpreter, analyst Muhammad Zulfikar Rakhmat describes a proposed network of about 2,772 kilometres linking mining and plantation areas to ports, at a cost that could reach roughly $40 billion. China is again being discussed as both the lender and the builder. That combination is what makes the piece a warning rather than a cheer.

The reason is the last railway. Whoosh, the fast train between Jakarta and Bandung, ran past its $7.3 billion budget because land purchases were slow, utility lines had to be moved, building costs climbed and the financing arrived late. Jakarta is still repaying that loan. Rakhmat's point is not that China is the wrong partner. It is that the risk sat almost entirely on the Indonesian side, so every delay turned into more Indonesian debt.

Kalimantan has one advantage Whoosh never had. Its trains would mostly carry coal, minerals and timber rather than passengers, and freight pays more predictably: a mining company signs for tonnes per year, while commuters can simply choose the road. Rakhmat wants that advantage locked in before anything is built. Sign binding cargo contracts first, construct the line in stages instead of all at once, and spread the money across several lenders and partners so one delay does not land on the state alone.

Why it matters

A $40 billion loan is repaid from the same budget that pays for schools, clinics and fuel support, so the terms agreed now decide what is affordable in ten years. If you live along the proposed route, the early fight will be over land purchases, which is exactly where Whoosh stalled, so ask what compensation rules apply before surveyors arrive. Watch whether the government publishes freight contracts and the list of lenders before construction starts, because that is the difference between a project with customers and a project with a deadline.
