Trans-Saharan railway proposals (1879-1940s)
French colonial planners proposed a railway from Algeria across the Sahara to the Niger River and West Africa. Survey expeditions in the 1870s and 1880s mapped routes, but the line was never built. The Sahara's vast distances and cost defeated every attempt.
The proposals remained on paper; no trans-Saharan rail was ever completed.
The idea persisted for decades as a symbol of French imperial ambition, but the Sahara remained unconnected by rail.
Algeria's current project revives a century-old ambition to link the Mediterranean to West Africa by rail, now with modern engineering and financing.
