The Netherlands–South African Railway Company (Nederlandsche Zuid-Afrikaansche Spoorwegmaatschappij; Nederlands-Suid-Afrikaanse Spoorwegmaatskappy) 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).
