Lacking any railways, Burundi does not share rail links with adjacent countries, but a Chinese study in August 2006 resulted in a promise to construct a railway starting at the existing Tanzanian railway network, connecting at Isaka, running via Kigali in Rwanda, through to Burundi. Tanzanian railways use a one metre gauge, although other neighbouring countries utilise the 1067mm gauge, leading to some potential difficulties. Also, another project was launched in the same year, which aimes to link Burundi and Rwanda (which also has no railways) to the Democratic Republic of the Congo and Zambia, and therefore to the rest of Southern Africa. At a meeting to inaugurate the Northern Corridor Transit Coordination Authority (NCTCA), the governments of Uganda and Burundi backed the proposed new railway from the Ugandan western railhead at Kasese into the Democratic Republic of Congo. Additionally, Burundi has been added to a planned railway project to connect Tanzania and Rwanda.
