Somaliland is a self declared state in the north west of Somalia, the location of the former colony of British Somaliland. It is generally recognized by the international community as an autonomous region of Somalia, although not sovereign.
There are no railways in Somaliland. However, the Ethiopian government has reached an agreement with the port of Berbera whereby it would take a financial interest in the port in return for the provision of new infrastructure, probably including a rail connection with Ethiopia. The Federal Government of Somalia opposes the deal.
