The Madeira-Mamoré Railroad is a railroad built in the Brazilian state of Rondônia between 1907 and 1912. The railroad links the Brazilian cities of Porto Velho and Guajará-Mirim. It became known as the "Devil's Rail-road" because thousands of construction workers died from tropical diseases and violence. There is a legend that a cadaver is buried underneath each sleeper.
In 1846 the engineer José Augustin Palácios and the Swiss German engineer Rudolf Oscar Kesselring convinced Bolivian authorities that the best way to secure access to the Atlantic ocean was through the Amazon. At the time, Bolivia had access to the Pacific ocean(subsequently lost to Chile in the war of the pacific in 1884), but the lucrative trade routes with the United States and Europe were located in the Atlantic. In 1851, the government of the United States became interested in access to Bolivian products (notably rubber), and contracted Lieutenant Lardner Gibbon to study the viability of a rail link between the navigable Amazon river and Bolivian production centres. Gibbon's study concluded that a rail-road along the Madeira river rapids would allow efficient transport of goods from the Bolivian capital of La Paz to US markets. 
During the 1870s, the American George Earl Church made two attempts to overcome the Madeira river rapids in order to gain access to Bolivian rubber markets. Both efforts were defeated by the difficult terrain and by appalling loss of life to malaria, accidents, and violence. A successful bid to build the rail-road began with the Treaty of Petrópolis (1903) whereby Bolivia gave Brazil the territory of Acre (191,000 km²), in exchange for Brazilian territory, a monetary payment, and a pledge that Brazil would build a rail-link to bypass the rapids on the Madeira river. Construction began in 1907, and on April 30, 1912, the final leg of the Madeira-Mamoré Railway was inaugurated.
The "Devil's Rail-road"
There are no accurate figures for the number of lives lost during the construction of the rail-road. In his book "Brazil", novelist Errol Lincoln Uys puts the number between 7000 and 10,000. The Brazilian government estimates 6,000 workers lost their lives. Fiorelo Picoli in his book, O Capital e a Devastação da Amazônica, puts the figure at more than 30,000.The loss of life may seem low compared to other complex constructions projects in difficult terrain. By comparison, construction of the Panama Canal claimed 30,609 lives (5609 workers died during the 10 year US management, the remainder perished while under the jurisdiction of France). However, much of the "devil's rail-road" legend is based on the much deadlier failed attempts by George Church, and on the Brazilian rubber boom itself, which cost tens of thousands of lives.
Competition from Roads and Dams
The South American rubber boom ended because of competition from Asian producers and synthetic rubber, and the rail-road became redundant. Initially, the Brazilian government was forced to maintain the superfluous facilities because of its obligations under the Treaty of Petrópolis. However, in 1972 Brazil completed the Trans-Amazonian highway linking Bolivia to navigable regions of the Amazon and the rail-road was abandoned. The (IIRSA) South American integration project includes a series of hydroelectric dams that will transform the Madeira river rapids into navigable lakes, finally realizing Gibbon's vision of fast and efficient access to Bolivian markets (two of the four dams already exist, the Santo Antônio Dam and the Jirau Dam). If the project is completed, "more than 4,000 km of waterways upstream from the dams in Brazil, Bolivia, and Peru would become navigable."
