Creole Swahili is the principal language of the Copperbelt mining cities and is somewhat more different from classical East African Swahili than that spoken elsewhere along the eastern edge of Congo. Most people can communicate in French, and many of the elite are more at ease in French than Swahili. English is widely spoken in businesses.
Connections via Zambia to Dar es Salaam and to South Africa.
Freight trains connect to Zambia, Dilolo to the west on the Angolan border in Katanga province, Ilebo to the far northwest in Kasai Province with river transport on to Kinshasa, and via Kamina to Kindu and Kalemie (Lake Tanganyika border with Tanzania) to the north. Passenger service is infrequent and slow without international connections. Angola is completing rebuilding of the link from Dilolo to the ocean at Lobito after decades of war, and a direct rail link to Kinshasa, connecting on to the Atlantic coast, is again being planned.
