Trans-Borneo Railway Feasibility Study Advances as Interim Findings Submitted to Transport Ministry

Kuala Lumpur, March 2026 - The proposed Trans-Borneo Railway linking Sabah and Sarawak has progressed to the interim feasibility reporting stage after consultants briefed Malaysia’s Ministry of Transport on preliminary findings. The study, launched in June 2025 under an RM7 million federal allocation, will assess the technical and economic viability of a cross-island rail corridor exceeding 1,600 km. Final reporting is scheduled for mid-2026, establishing the first formal implementation framework for a Borneo-wide railway network.

The Ministry of Transport confirmed that further consultations with the authorities of Sabah and Sarawak are ongoing to refine the corridor alignment, station siting, and integration with regional development plans. The feasibility study includes operational modelling, demand forecasting, governance structures, and cost-benefit analysis prior to any federal decision on project implementation.

Preliminary technical concepts under review include a regional railway corridor linking Sabah, Sarawak, Brunei, and Indonesia’s Kalimantan, with an indicative network length estimated at approximately 1,620 km. Early private-sector concept proposals referenced potential operating speeds of up to 350 km/h, although no technology specification, rolling stock strategy, or delivery model has been formally adopted.

Engineering assessments also examine potential interoperability with Sarawak’s Kuching Urban Transportation System (KUTS) and evaluate freight–passenger service configurations, right-of-way constraints, and cross-border regulatory frameworks. The final study deliverable will include a staged implementation programme, an indicative capital expenditure envelope, and an institutional governance structure for a multi-state rail programme.

Delivery risk remains significant due to the scale of greenfield civil works across mountainous terrain and the requirement for intergovernmental coordination across multiple jurisdictions.

Strategically, the corridor could establish the first continuous rail backbone across Borneo, enabling long-distance freight and passenger flows while improving connectivity between Sabah, Sarawak, Brunei, and Indonesia’s Kalimantan economic regions.
