The Netherlands–South African Railway Company (; ) or NZASM (also sometimes called SASM in South Africa) was a railway company established in 1887. The company was based in Amsterdam and Pretoria, and operated in the South African Republic (ZAR) during the late 19th century. At the request of ZAR president Paul Kruger, the NZASM constructed a railway line between Pretoria and Lourenço Marques in Portuguese East Africa (now Maputo in Mozambique). Background The British conquered the then Dutch Cape Colony in 1806. The new administration was not universally accepted by the Dutch colonists and after the 1830s thousands of Dutch-speaking colonists (called Boers) migrated to the interior of Southern Africa. This migration, known as the Great Trek, resulted in the establishment of 14 independent republics. By the mid 19th century these republics had merged into the two larger republics: The South African Republic (ZAR) and the Republic of the Orange Free State. The British Empire eventually recognized the independence of these republics in 1852 and 1854. The relationship between the British and the Boers remained strained throughout the 19th century, especially as a result of the First Boer War (1880–81). Both republics were located in the interior of what is now South Africa, with no route to the coast that did not pass through the British-held Cape Colony and Colony of Natal. Paul Kruger, president of the ZAR, decided that an alternative trade route to the ocean was a priority for the ZAR. The Witwatersrand Gold Rush after 1886 resulted in the rapid industrialization of the ZAR, making access to the ocean even more important, and allowed the suddenly cash-flush republic to invest in large-scale infrastructure projects. Establishment In 1874 the Volksraad of the ZAR decided that a railway would be built connecting the ZAR with Lourenço Marques on Delagoa Bay in Portuguese East Africa (now Maputo in Mozambique). A commission was established in 1874 to create a plan for the construction of this railway. After initial success in raising capital and acquiring a railway concession from the Portuguese government, the project was stalled by the outbreak of the First Boer War. After the end of the war in 1881 the project was resumed, this time with renewed enthusiasm due to the threat of British domination over the Boer Republics. In 1884 a concession was granted to a group of Dutch investors, and this was followed by the official establishment
