There are three main options of the railway transportation project.
Option 1 — freight transfer is carried out by double headers of G26CU series; train crossing is performed at the Conakry station.
Option 2 — freight transfer is carried out by double headers of G26CU series; train crossing is performed at separate haul points.
Option 3- freight transfer is carried out by double headers of G26CU series, train crossing is performed at the switching tracks.
Option 2 is recommended for the following reasons:
— As the trains do not cross at the end points, Conakry and Kimbo stations are off loaded;
— The possibility for further increasing the volume of freight traffic in the long term;
— Minimizing the number of transfers per day.
