Overview


The Transgabonais railway line is a single track line connecting the port of Owendo (Libreville) to Franceville and Moanda Merchandise. It was built between the 1970s and the 1990s in two sections: Owendo-Booué and Booué-Franceville. Commissioning of the line was progressive, the first section (Owendo-Ndjole) in 1978, the second section (Ndjole-Booué) in 1981 and the last section (Booué-Franceville) in 1986.
