The Trans-Borneo Railway (Malay: Kereta Api Trans-Borneo ) is a proposed international railway network that will connect the territories of Malaysia, Brunei and Indonesia on the island of Borneo. The proposed network will link major urban, logistics and industrial centres in Sabah, Sarawak, Brunei and Kalimantan.
Currently, there is only one operational rail network on the island of Borneo which is the Sabah State Railway; a 134-kilometre single track line that connects Tanjung Aru, Kota Kinabalu to Tenom.
Background The island of Borneo which is among the world's largest islands and home to over 20 million inhabitants does not possess an extensive rail network. Rail transport currently only exists in Sabah linking the West Coast and Interior of Sabah, the metre gauge single track Western Sabah Railway Line. Recent developments such as Indonesia's planned move of its capital to Kalimantan as well as increased focus on development in East Malaysia has increased the push for a comprehensive rail network for Borneo. Brunei-based Brunergy Utama Sdn Bhd proposed and outlined plans for a US$70 billion project. The proposal entailed two routes covering 1620 km with high-speed trains reaching 300–350 km/h. In March 2026. the Malaysian Transport Minister Anthony Loke mentioned that a feasibility study for the rail network is underway and expected to be completed by mid 2026. He estimated that the rail network would take decades to be fully constructed. The study looks into the proposed rail alignments and possible integration with the under construction Kuching Urban Transportation System.
