Tanzania is seeking $5.6-billion for a new railway in the south linking the Indian Ocean to Lake Nyasa and traversing regions rich in iron-ore, coal and graphite. The East African nation is looking for public-private partnerships for the 1 000 km line, according to a presentation by Tanzania Railways Corp MD Masanja Kadogosa. The agency made a pitch to investors and financiers at the Africa Investment Forum in Marrakech, Morocco, earlier this month and secured at least $2.2-billion of interest in the project, he said.
