Instability in Ivory Coast in 2003 forced a rerouting of rail freight from the Abidjan corridor to ports in Togo, Benin, and Ghana via the road network. A proposed rail link between Ouagadougou and Pô in Burkina Faso and Kumasi and Boankra in Ghana, has been discussed with Ghanaian officials, and feasibility studies are being undertaken to explore this possibility, which would provide rail access to the inland port of Bonakra. Burkina Faso and Ghana use different rail gauges and this break-of-gauge can be overcome to a greater or lesser extent with a number of methods.
