Mediterranean–Niger Railway

The Mediterranean-Niger-Railway (MN) (French: Chemins de Fer de la Méditerranée au Niger) was a railway in Western Africa.

The Mediterranean-Niger Railway was built between the coal mining region near Bou Arfa in the east of Morocco and the Algerian rail system at Oujda, completed as a standard gauge route between Oran and Oujda in 1922, while Fes was reached in 1934.

In 1940/41 construction was begun on the Algerian segment of the Mediterranean-Niger-Railway as part of the Trans-Saharan Railway. The line made a connection with the Moroccan segment, which had been completed in 1931, at Bou Arfa and continued into Algeria to connect with the narrow gauge line Oran - Colomb-Béchar built in 1910.

In 1963 Morocco nationalized its railroad system under the name of Moroccan Railways (Office National des Chemins de Fer du Maroc ONCF). MN was liquidated. The part of MN from the Southern border to Colomb-Béchar was closed. Colomb-Béchar was still reached by the narrow gauge line.
