branch and spur have since closed to traffic. The Central is extended by the Ferrocarril Huancayo - Huancavelica which was authorised in 1904 (engineer: Charles Weber) but work was interrupted during the World War I and it was not opened throughout ( of gauge) until 1926. Work was continued but never completed on extending the line to the Pacific coast. After a period under provincial government control it was agreed in June 2006 by the Peruvian government that FCCA should go ahead with converting the line to (as had in fact been intended prior to 1919). Estimated to take 16 months, the US$33m project was to be funded jointly by the government and the Development Bank of Latin America. Also connecting with the Central, at La Oroya, is the Cerro de Pasco railway opened in standard gauge form in 1904 to serve ore mining in the Cerro de Pasco district. It was thoroughly North American in all its operations and, although primarily a mineral line, did run a passenger operation, latterly known as the “Flamingo” from the consist purchased from the Florida East Coast Railway. The owning company was nationalised as Centromín in 1974 and operation of the railway was taken over by FCCA. of gauge was completed of a Tambo del Sol-Pachitea line intended eventually to extend to the head of Amazon navigation on the Ucayali River at Pucallpa; this aspiration was abandoned by the government in 1957. The Southern Railway, Ferrocarriles del Sur del Perú (FCS), another Meiggs concession, was completed from Arequipa to Puno in 1876 and to the coast at Matarani. The railway also operated steamers (including the Yavari) and train ferries on Lake Titicaca connecting with Guaqui in Bolivia. Although work on the Juliaca–Cuzco section was begun in 1872 it was not completed through until 1908. The summit of this section is reached at La Raya ( above sea level). Since 1999 it has been operated by PeruRail, an affiliate of the Belmond Ltd. group, whose tourist trains form the only passenger services. From Cuzco, the gauge Ferrocarril Santa Ana (Ferrocarril Cuzco á Santa Ana) (engineer: Mauro Valderrama) was authorised in 1907, originally at gauge, but the first section was not opened until the early 1920s. It was extended to Aguas Calientes () in 1928, passing to government control in 1931. Although further extended in stages through to Quillabamba (reached in 1978), landslides (attributed to
