The Government of Indonesia is exploring foreign investment to develop the proposed 2,772-km Trans-Kalimantan railway network across Kalimantan, with China and Russia having expressed interest in the project. The network is planned as part of Indonesia’s long-term railway expansion through 2045 and would connect areas across the resource-rich region, including the country’s planned new capital, Nusantara. Kalimantan currently has no operational public railway network.

The project is expected to involve significant technical, geographical and financial challenges due to Kalimantan’s terrain and environmental conditions. Potential Chinese participation could cover financing, engineering, technology and construction, although Indonesia is expected to assess financing structures and commercial risks carefully based on experience with the 142.8-km Jakarta–Bandung high-speed railway.
