The Trans-Gabon Railway () is the only railway in Gabon. It runs some 648 km (about 670 km including yards and branches) eastward from the port of Owendo, on the outskirts of the capital Libreville, to Franceville in the south-east of the country, serving 23 intermediate stations, the most important of which are Ndjolé, Lopé, Booué, Lastoursville and Moanda. It is built to standard gauge (1,435 mm) as a single, unelectrified track and is operated with diesel locomotives.

Conceived as a linchpin of Omar Bongo's post-independence modernisation drive, the line was financed largely from Gabon's 1970s oil windfall, supplemented by French, West German and later British and Italian capital after the World Bank declined to fund the project on economic grounds. Construction began in October 1974; the first section, Owendo–Ndjolé, was opened in 1978, and the line reached Franceville on 30 December 1986. The cost of roughly substantially exceeded early estimates and strained Gabonese public finances for more than a decade.

The railway is operated under a long-term concession by the Société d'Exploitation du Transgabonais (SETRAG), a subsidiary of the manganese producer Compagnie minière de l'Ogooué (COMILOG), which is itself majority-owned by the French mining and metallurgical group Eramet. Manganese ore shipped from the Moanda mine to Owendo for export accounts for the overwhelming majority of freight traffic; the line also moves okoumé and other tropical timber, uranium ore concentrates from the former Mounana mine area, general freight and, under a public-service obligation, passengers. In 2022 the line carried approximately 248,000 passengers and 10.9 million tonnes of freight.

Background

A railway crossing Gabon was first mooted during the colonial period, with proposals advanced as early as 1885 and periodically revived during French Equatorial African rule. None of these schemes was acted upon, and until the 1970s Gabon possessed no railway of its own, relying instead on the Ogooué River and on the Congo–Ocean Railway in neighbouring Moyen-Congo (later the Republic of the Congo) for bulk exports.

From the 1950s the manganese deposits at Moanda were exploited by COMILOG, founded in 1953 with U.S. Steel as a significant shareholder. Lacking rail access inside Gabon, the company constructed the COMILOG Cableway, which at the time of its commissioning in 1962 was among the longest aerial ropeways in the world; it linked Moanda with the railhead at Mbinda in Moyen-Congo, whence ore was forwarded by the Congo–Ocean Railway to Pointe-Noire for export. Reliance on a foreign corridor for the country's principal mineral export was politically unsatisfactory and became a central argument for building a Gabonese railway.

Financing was assembled piecemeal. Besides direct expenditure from the Gabonese oil budget, loans and aid were provided by France, West Germany and several international organisations. In 1979 and the early 1980s, as cost overruns mounted, additional financing was provided by a British-led consortium following the discovery of commercially significant uranium deposits; the Thatcher government saw strategic value in underwriting continued work, and British expatriate personnel and contractors – including Taylor Woodrow and staff seconded from Wimpey International – joined the site.

Construction

Civil works began in October 1974. The civil-engineering consortium drew in Impregilo and Astaldi of Italy, Philipp Holzmann of West Germany, and the French companies Constructions et Entreprises Industrielles (CEI) and Entreprise de Construction Franco-Africaine (ECFA).

The first section, Owendo–Ndjolé (about 181 km), was opened to traffic in 1978 (the Encyclopædia Britannica gives 1979 for the opening ceremony). The Booué–Franceville section, some 357 km long, was completed and opened on 30 December 1986 in the presence of French Prime Minister Jacques Chirac; service to Franceville began in early 1987.

Signalling and telecommunications were originally provided by conventional trackside equipment. In 2003 Hughes Network Systems installed a satellite-based telephony system covering all stations, replacing a deteriorating line-side microwave network.

Operations

Operating history

From the opening of the first section in 1978 the railway was operated by a state-owned enterprise, the Office du Chemin de Fer Transgabonais (OCTRA). The initial concessionaire was a consortium led by the state forestry company Société nationale des bois du Gabon (SNBG) in partnership with the Belgian firm Transurb.

Traffic

Documented traffic figures indicate the growth of the line since opening. In 1996 – the first year for which broadly cited data are available – the railway carried approximately 3 million tonnes of freight and 190,000 passengers. The most recent contract, signed in early 2022, covered six DF8B heavy-haul diesels together with ten years of maintenance; CRRC Ziyang states that in three-locomotive multiple-unit operation the type can haul continuous trailing loads of up to 11,000 t on an 8.3 ‰ gradient, meeting the requirements for heavy manganese services. The project was financed jointly by SETRAG and the Gabonese government, with loans from the International Finance Corporation (IFC) and its French counterpart Proparco, including a €32.5 million Proparco loan signed on 26 June 2016. The stated aim of the programme is to raise the corridor's capacity to 16 daily train paths (eight per direction), to improve the reliability and safety of passenger services, and to upgrade critical structures and unstable sections. According to Eramet, Gabon is the world's fourth-largest producer of manganese ore and the Transgabonais is "the backbone of national economic development". The extension of rail transport inland has also been linked to the commercial exploitation of dense heartwood species that were previously uneconomic to move because they could not be floated down the Ogooué.

Operationally, derailments on sections built over waterlogged embankments have been a recurrent source of service disruption since the 1990s. In 2017 SETEC, the French engineering consultancy, was engaged by SETRAG to delimit and propose consolidation measures for unstable zones along the entire Owendo–Franceville alignment. The agreement was suspended amid environmental opposition and subsequent political changes and has not, as of 2026, produced any rail construction; in February 2023 the Australian mining group Fortescue signed a further agreement to develop Bélinga, again envisaging combined road and rail evacuation to an existing port.
