The Benguela Railway () is a Cape gauge railway line that runs through Angola from west to east, being the largest and most important railway line in the country. It also connects to Tenke in the Democratic Republic of the Congo (DRC), and to the Cape to Cairo Railway (connecting the city of Kindu (DRC) to the city of Port Elizabeth in South Africa). The line terminates at the port of Lobito on the Atlantic coast, from where Angola exports a wide variety of products, including minerals (from the Copperbelt region), food, industrial components and livestock. The section from Lobito to Luau is run by the Empresa do Caminho de Ferro de Benguela-E.P. It crosses the Luao River, which lies on the border, to Dilolo (DRC). From there to Tenke, the railway is operated by the Société nationale des Chemins de fer du Congo. Specifications The railway is Cape gauge, , which is used by most mainline railways in southern Africa. The maximum design speed is 90 km per hour. The design capacity is 20 million tons of cargo and 4 million passengers per year. There are 67 stations and 42 bridges along the route of the railway. The highest point on the railway is . Equipment Locomotives History The railway line roughly follows old trade routes between the ancient trading centre of Benguela and its hinterland of the Bié plateau. In 1899, the Portuguese government initiated the construction of the railway to give access to the central Angolan plateau and the mineral wealth of the then Congo Free State. A concession, running for 99 years, was granted to Sir Robert Williams on 28 November 1902. His Benguela Railway Company took over the construction which commenced on 1 March 1903. Messrs Pauling & Co. and Messrs Griffiths & Co were contracted to build sections of the railway. By 1914, when World War I started, had been completed. Construction was halted until 1920 after which the railway's connection to Luau at the border to the Belgian Congo was completed in 1929. The primary purpose was to facilitate export trade, while "the domestic Angolan traffic would be of secondary importance." Passenger trains also ran between Lubumbashi and Lobito, connecting with passenger ship services to Europe. This provided a shorter route for Europeans working in the Katangan and Zambian Copperbelt, and the name "Benguela Railway", or also "Katanga-Benguela railway", was sometimes used loosely
