The Trans-Gabon Railway is a single-track route linking the Owendo mineral port in Libreville to Franceville. Operated by Setrag, this line crosses 669 km of Gabon, through the Equator and the Equatorial Forest (4,000 mm of rain annually). The Trans-Gabon Railway serves as a vital link in the Gabonese economy, with its trains spanning more than a kilometer to carry manganese to Owendo for export. It is built on difficult terrain, with waterlogged embankments causing numerous derailments. setec teams are carrying out diagnostics for Setrag, focusing on the unstable zones of this rail line. The most complex part of the project is proposing repair solutions while the railway is in operation, as the only transport link through the jungle.
