On 24 June 2015, an operating contract called the Multi-User Boké Railway (CFB) was signed between the Agence Nationale d'Aménagement des Infrastructures Minières (ANAIM), the Compagnie des Bauxites de Guinée (CBG), Guinea Alumina Corporation ("GAC") and the Compagnie de Bauxites et d'alumine de Dian Dian (COBAD), with a view to increasing the capacity of the tracks to transport 51 million tons of bauxite per year from 2021 and up to 70 million in 2024.
The project has two bodies, a technical committee and a users' committee, made up of representatives from the companies involved in the contract and ANAIM.

In its new role, the management of the CFB is responsible for the operationalization of the railway for the transport of the ores of the three signatory companies to the contract.
The work to reinforce the existing railway is being carried out in various stages: earthworks and laying of new tracks, installation of a new on-board signalling system, increasing the locomotive fleet, and finally the definition and implementation of the operational readiness plan.

The project also includes a considerable increase in manpower and equipment for track maintenance and the modernisation of the existing maintenance workshops.

The pooling of this infrastructure is intended to support the establishment of new companies in the Boké Region, which will undoubtedly contribute to the socio-economic development of the region and of Guinea.
