The Mozambican railway system developed over more than a century from three different ports on the Indian Ocean that served as terminals for separate lines to the hinterland.  The railroads were major targets during the Mozambican Civil War, were sabotaged by RENAMO, and are being rehabilitated. A parastatal authority, ''Portos e Caminhos de Ferro de Moçambique'' (abbreviated CFM; in English- Mozambique Ports and Railways), oversees the railway system of Mozambique and its connected ports, but management has been largely outsourced.  Each line has its own development corridor.
