Cementerio de trenes’, the antique train cemetery, 3 kilometers (1.9 miles) outside the town. From the end of the 19th century till this day, Uyuni has been an important transportation hub for trains. The rail lines, constructed between 1888 and 1892, were built by British engineers who were invited by the British-sponsored Antofagasta and Bolivia Railway Companies. For the next decades the trains were used for carrying minerals from the Andes mountains to the Pacific Ocean ports.
