Built between 1904 and 1910, a railway once linked Conakry to Kankan via Kouroussa but it ceased operating in 1995 and had been dismantled altogether by 2007 with rails mostly stolen and/or sold for scrap. Plans had at one time been mooted for the passenger line to be rehabilitated as part of an iron-ore development master plan but although the start of work was announced in 2010, corruption charges led the whole master plan to be paused and the line was only rebuilt as a 105 km mineral railway, paralleling the old route as far as the mines of Kalia. There is also a state run mineral railway linking the bauxite mines of Sangarédi to the port of Kamsar (137 km) and a 1960s narrow-gauge line operated by Russian aluminium producer RusAl to the mines at Fria (143 km).
