Railways have historically been generators of economic growth, connecting new markets to existing ones, finding buyers in the interior for manufacturers on the coast. North America, for example, would never have become the economic powerhouse it became at the turn of the last century, had railways not laid down a dense web of lines. Indeed, by 1900, the rails blanketed the continent., their uniform gauge making possible the quick transfer of freight from Canada to the U.S. and vice versa.
But Africa is missing out on the economic blast that only railways can provide. More than 100 years after Cecil Rhodes dreamed of a Cape-to-Cairo line, the continent seems no closer than it was then to realizing Rhodes`dream.
And although dozens of rail lines run from various points on the coast to various parts of the interior, these tracks don`t even begin to suggest the likelihood of a continent-wide railway network — a network that will be difficult to build, given the different gauges that are now being used.
