The Madeira-Mamoré Railroad is an abandoned railroad built in the Brazilian state of Rondônia between 1907 and 1912. The railroad links the cities of Porto Velho and Guajará-Mirim. It became known as the "Devil's Railroad" because thousands of construction workers died from tropical diseases and violence.
