The toolkit presented here is intended to provide African countries, in summary form, with an overview of the experience to date with railway concessioning in Sub-Saharan Africa. The reader will note that the Guide refrains from defining ìtheî model concession arrangement to be applied in every circumstance; no such model exists, and each individual situation calls for individualized solutions. But the wealth of accumulated experience should at least make it possible to avoid repetition of some of the mistakes that the pioneers with concession operations did indeed make in the course of the process, the complexity of which could hardly be underestimated.
