The main aim of constructing the railway systems in West Africa was to evacuate raw materials and minerals for export. The railway systems were constructed during the colonial era to facilitate the transportation of natural resources from the hinterland to the coastal ports for export to Europe. The resources that were transported included minerals such as gold, tin, and diamonds, as well as agricultural products such as cocoa, palm oil, and groundnuts. The railway systems were also used to transport goods and people between the different towns and cities in the region. While the railway systems did link different areas of the region, their primary purpose was to facilitate the export of natural resources.
