Four of these capitals - Sucre or Chuquisaca, La Paz, Cochabamba and Oruro - have served as the national capital, and Sucre was chosen, but after the revolution of 1898 the capital was at La Paz, which is the commercial metropolis and is more accessible than Sucre.
Among the smaller towns prominent because of an industry or commercial position, may be mentioned the Huanchaca mining centre of Pulacayo (pop. 6512), where 3200 men are employed in the mines and surface works of this great silver mining company; Uyuni (pop. 1587), the junction of the Pulacayo branch with the Antofagasta and Oruro railway, and also the converging point for several important highways and projected railways; and Tupiza (pop. 1644), a commercial and mining centre near the Argentine frontier, and the terminus of the Argentine railway extension into Bolivia.
Up to 1903 the only railways in Bolivia were the Antofagasta and Oruro line, with a total length of 574 m., of which 350 m.
Lines were in 1907 projected from La Paz to the navigable waters of the Beni, from La Paz to Cochabamba, from Viacha to Oruro, from Uyuni to Potosi and Sucre, from Uyuni to Tupiza, and from Arica to La Paz via Corocoro.
The latter includes the lines belonging to the Antofagasta and Oruro railway, which are partly within Chilean territory.
