[2] OTRABU periodically contracted with the Office National de la Tourbe (ONATOUR) to transport peat from its bog sites to Bujumbura.
OTRABU obtained sophisticated Mercedes trucks to operate this route, helped by German technical cooperation.
[2][a] After its collapse, transport services in the Northern and Central Corridors were provided by private road hauliers, mostly registered in Burundi.
[10] In October 1984 a team from the Japan International Cooperation Agency met with the Burundi government representatives to discuss a project for building bus maintenance facilities for OTRABU in the New Industrial Zone of Bujumbura.
[6] A May 1988 report from the International Development Association on a proposed development credit of SDR 64.9 million to the Republic of Burundi found that OTRABU had the potential to become profitable through a rehabilitation program based on partial privatization and elimination of all government subsidies, combined with improvements to internal management, fleet composition and a now focus on profitable activities and customers.
