In the early stage of railway construction, the tunnel has a total length of 11.62 kilometers and a design speed of 120 kilometers per hour. It is a single-hole double-track structure, which marks the entry of the Massi-Western Railway into the implementation stage. The Jindia Tunnel project adopts Chinese standards, Chinese technology, and Chinese equipment. After completion, it will become the longest tunnel in Guinea.
It is understood that the Masai Railway is an important supporting project for the development of the No. 1 and No. 2 ore blocks in the Simandou mining area. The mining area has a world-class large-scale high-quality open-pit hematite mine and is regarded as the world’s largest undeveloped mining area with the largest reserves and the highest quality. , The proven reserves are about 2.25 billion tons, and the total resources may reach 5 billion tons, which has extremely high commercial exploitation value. The Masai Railway is an important infrastructure that integrates into the "Belt and Road" initiative and optimizes the economic structure of Guinea.
