Railways.—Railway construction began in 1859 when a private company built a line from Cape Town to Wellington. This line, 64 m. long, was the only railway in the colony for nearly fifteen years. In 1871 parliament resolved to build railways at the public expense, and in 1873 (the year following the conferment of responsible government on the colony) a beginning was made with the work, £5,000,000 having been voted for the purpose. In the same year the Cape Town-Wellington line was bought by the state. Subsequently powers were again given to private companies to construct lines, these companies usually receiving subsidies from the government, which owns and works the greater part of the railways in the colony.
The plan adopted in 1873 was to build independent lines from the seaports into the interior, and the great trunk lines then begun determined the development of the whole system. The standard gauge in South Africa is 3 ft., 6 in. and all railways mentioned are of that gauge unless otherwise stated.
The railways, which have a mileage exceeding 4000, are classified under three great systems:—the Western, the Midland and the Eastern.
The Western system—the southern section of the Cape to Cairo route—starts from Cape Town and runs by Kimberley (647 m.) to Vryburg (774 m.), whence it is continued by the Rhodesia Railway Co. to Mafeking (870 m.), Bulawayo (1360 m.), the Victoria Falls on the Zambezi (1623 m.) and the Belgian Congo frontier, whilst a branch from Bulawayo runs via Salisbury to Beira, 2037 m. from Cape Town. From Fourteen Streams, a station 47 m. north of Kimberley, a line goes via Klerksdorp to Johannesburg and Pretoria, this being the most direct route between Cape Town and the Transvaal. (Distance from Cape Town to Johannesburg, 955 m.)
The Midland system starts from Port Elizabeth, and the main line runs by Cradock and Naauwpoort to Norval’s Pont on the Orange river, whence it is continued through the Orange River Colony and the Transvaal by Bloemfontein to Johannesburg (714 m. from Port Elizabeth) and Pretoria (741 m.). From Kroonstad, a station midway between Bloemfontein and Johannesburg, a railway, opened in 1906, goes via Ladysmith to Durban, and provides the shortest railway route between Cape Town and Port Elizabeth and Natal. From Port Elizabeth a second line (186 m.) runs by Uitenhage and Graaff Reinet, rejoining the main line at Rosmead, from which a junction line (83 m.) runs eastwards, connecting with the Eastern system at Stormberg. From Naauwpoort another junction line (69 m.) runs north-west, connecting the Midland with the Western system at De Aar, and affords an alternative route to that via Kimberley from Cape Town to the Transvaal. (Distance from Cape Town to Johannesburg via Naauwpoort, 1012 m.)
The Eastern system starts from East London, and the principal line runs to Springfontein (314 m.) in the Orange River Colony, where it joins the line to Bloemfontein and the Transvaal. (Distance from East London to Johannesburg, 665 m.) From Albert junction (246 m. from East London) a branch, originally the main line, goes east to Aliwal North (280 m.).
The west to east connexion is made by a series of railways running for the most part parallel with the coast. Starting from Worcester, 109 m. from Cape Town on the western main line a railway runs to Mossel Bay via Swellendair and Riversdale. From Mossel Bay another line runs by George, Oudtshoorn and Willowmore to Klipplaat, a station on the line from Graaff Reinet to Port Elizabeth. (Distance from Cape Town 666 m.) From Somerset East a line (164 m.) goes via King William’s Town to Blaney junction on the eastern main line and 31 m. from East London. The Somerset East line crosses, at Cookhouse station, the Midland main line from Port Elizabeth to the north, and by this route the distance between Port Elizabeth and East London is 307 m. Before the completion in 1905 of the Somerset East-King William’s Town line, the nearest railway connexion between the two seaports was via Rosmead and Stormberg junction—a distance of 547 m. From Sterkstroom junction on the eastern main line a branch railway goes through the Transkei to connect at Riverside, the frontier station, with the Natal railways. It runs via the Indwe coal-mines (66 m. from Sterkstroom), Maclear (173 m.) and Kokstad. From Kokstad to Durban is 232 m. The eastern system is also connected with the Transkei by another railway. From Amabele, a station 51 m. from East London, a line goes east to Umtata (180 m. distant). Thence the line is continued to Port St Johns (307 m. from East London), whence another line 142 m. long goes to Kokstad.
Besides the main lines there are many smaller lines. Thus all the towns within a 50 m. radius of Cape Town are linked to it by railway. Longer branches run from the capital S.E. to Caledon (87 m.) and N.W. via Malmesbury (47 m.), and Piquetberg (107 m.) to Graaf Water (176 m.). A line runs N.W. across the veld from Hutchinson on the western main line via Victoria West to Carnarvon (86 m.). From De Aar junction, a line (111 m.) goes N.W. via Britstown to Prieska on the Orange river. From Port Elizabeth a line (35 m.) runs east to Grahamstown, whence another line (43 m.) goes south-east to Port Alfred at the mouth of the Kowie river. Another line (179 m.) on a two-foot gauge runs N.W. from Port Elizabeth via Humansdorp to Avontuur.
A line, unconnected with any other in the colony, runs from Port Nolloth on the west coast to the O’okiep copper mines (92 m.). It has a gauge of 2 ft. 6 in.
The railways going north have to cross, within a comparatively short distance of the coast, the mountains which lead to the Karroo. The steepest gradient is on the western main line. Having entered the hilly district at Tulbagh Road, where the railway ascends 500 ft. in 9 m., the Hex River Pass is reached soon after leaving Worcester, 794 ft. above the sea. In the next 36 m. the line rises 2400 ft., over 20 m. of that distance being at gradients of 1 in 40 to 1 in 45. The eastern line is the most continuously steep in the colony. In the first 18 m. from East London the railway rises 1000 ft.; at Kei Road, 46 m. from its starting-point, it has reached an altitude of 2332 ft., at Cathcart (109 m.) it is 3906 ft. above the sea, and at Cyphergat, where it pierces the Stormberg, 204 m. from East London, the rails are 5450 ft. above the sea. From Sterkstroom to Cyphergat, 15 m., the line rises 1044 ft. The highest railway station in the colony is Krom Hooghte, 5543 ft., in the Zuurberg, on the branch line connecting the Eastern and Western systems. The capital expended on government railways to the end of 1905 was £29,973,024, showing a cost per mile of £10,034. The gross earnings in 1905 were £4,047,065 (as compared with £3,390,093 in 1895); the expenses £3,076,920 (as compared with £1,596,013 in 1895). Passengers conveyed in 1905 numbered 20,611,384, and the tonnage of goods 1,836,946 (of 2000 ℔).
