High Quality Content by WIKIPEDIA articles! There are 84 kilometres of railway in Sierra Leone, all of which is private and of a narrow gauge, 1,067 mm (3 ft 6 in). Sierra Leone no longer has any common carrier railroads, as the 762 mm (2 ft 6 in) gauge Sierra Leone Government Railway from Freetown through Bo to Kenema and Daru with a branch to Makeni closed in 1974. The country does not share rail links with adjacent countries, Guinea and Liberia. Rail transport is the means of conveyance of passengers and goods by way of wheeled vehicles running on rail tracks. In contrast to road transport, where vehicles merely run on a prepared surface, rail vehicles are also directionally guided by the tracks they run on. Track usually consists of steel rails installed on sleepers/ties and ballast, on which the rolling stock, usually fitted with metal wheels, moves. However, other variations are also possible, such as slab track where the rails are fastened to a concrete foundation resting on a prepared subsurface.
