The Dakar-Port Sudan Railway is a 4,000 km long proposal which surfaced in 2008-2010 to link the aforementioned ports by a Transcontinental Railway. It would pass through several countries along the way and would have branches to link capital cities not on the direct route.[1][2][3]
The initial line would develop into a railway network that would cover the whole of Africa. By comparison, except for the extreme south and extreme north of Africa, railways are fragmentary, and hampered by differences in gauge.
